Skyrim Ram Limit Remover

  1. ; Info: Completely disable Skyrim's memory allocator and use regular C malloc. That means memory blocks will not exist anymore
  2. ; and game will not crash at some arbitrary limit. Theoretically it should also be faster (especially loading screens)
  3. ; IMPORTANT!!: You NEED custom plugin loader to run this so CrashFixPlugin.dll gets loaded before the game initializes!
  4. ; Here is the link to 'SKSE Plugin Preloader': http://www.nexusmods.com/skyrim/mods/75795/?
  5. ; When this is enabled then Safety Load and SSME/SKSE memory patch are not needed, but they don't cause any trouble if you do have them.
  6. ; Info: When the game crashes unexpectedly then write the relevant information from crash to Data/SKSE/Plugins/CrashLog/crash_time.txt
  7. ; If game crashes when running out of memory or has other issues it's possible for the file to not appear or become empty!
  8. ; If the game crashes in SKSE dll or a SKSE plugin dll then it's possible for the crash information to not appear.
  9. ; 1 - enabled (TL;DR set this for normal enable)
  10. ; 2 - don't write timestamp into file name but instead always write to crash_last.txt (overwritten by default)
  11. ; 4 - don't ignore already known crashes, usually ones that display a message box are ignored
  12. ; 8 - append file if it already exists instead of replacing
  13. ; 16 - when the game crashes CTD without a message box about game stopped responding
  14. ; Write messages that appear in error box also to file in 'Data/SKSE/Plugins/CrashFixPluginLog.txt'
  15. ; Info: Warn user on startup if ENB settings are incorrect.
  16. ; Info: Crash happens unknown constructor (TESObjectLAND::unk_24 object), movaps instruction is used
  17. ; but heap allocate did not allocate this object to have 16 align. Crash happens more frequently
  18. ; with high Ugrids because more cells are loaded and greater chance to misalign.
  19. ; Solution: Could align only this object or align all objects. Trying with all to see what happens since
  20. ; same error could be elsewhere as well and I think I have seen it elsewhere.
  21. ; Result: Fixes these type of crashes. Some people report longer loading times and higher memory usage with this enabled!
  22. ; Update: Disabled by default since it's incompatible with some ENB settings, higher memory usage and longer loading times.
  23. ; It's safe and probably good to enable if you are ok with those downsides. I have not personally experienced
  24. ; any incompatibility with ENB, some people say it messes up their game that's why I wrote it here.
  25. ; Info: Game crashes when strcmp is passed NULL char*
  26. ; Cause: Most frequently happens in TthkbClipGenerator::activate (0xBF2FB3),
  27. ; tracked issue to skeleton was deleted in another thread while
  28. ; this function is attempting to use it. Have seen in other places
  29. ; Solution: Unknown. This doesn't really fix it for BF2FB3 because it just pops up in foot IK.
  30. ; If patched in foot IK it pops up in hand IK, the problem is larger than just this.
  31. ; Still enabled because it may fix crashes in other places too this is a very common function.
  32. ; There's really no reason not to have it since the game would crash certainly with this off.
  33. ; Enable one. NoTry may be slightly faster but catches less crashes.
  34. ;StrCmpNoTry=1
  35. ; Info: Game crashes when strlen is used on NULL char*
  36. ; Cause: NiNode names are compared, one of the NiNode's name is NULL.
  37. ; NiNode ** v72 = NiNode::children.data - this is iterated until count
  38. ; const char * v56 = v69->name;
  39. ; {
  40. ; const char * v57 = v72[v49]->name; // <- v57 name is not checked for NULL for some reason ?
  41. ; _strnicmp(v56, v57, strlen(v57)); <- strlen on NULL, also result is not even used anywhere!
  42. ; Solution: Unknown, temporarily bypass whole strcmp since it's unused.
  43. StrLen=1
  44. ; Info: Unknown, reported as loading save game.
  45. ; Address: 8B437C - vtable seems to be 0 or wrong pointer is used.
  46. ; Solution: Skip since this is the last part of the function and already has a check anyway
  47. ; Info: Unknown, reported as loading save game. Possibly related to rendering. First
  48. ; argument is gNiDX9Renderer->unk_650 which is a pointer.
  49. ; Address: CEC5EC - null pointer is passed as second argument to function, this function does not expect it
  50. ; Solution: Bypass using argument if it's null. Maybe doesn't fix.
  51. ; Info: Unknown, no info was provided. // char __thiscall TESObjectREFR::unk_4D4EB0(TESObjectREFR *this)
  52. ; Solution: Bypass and pretend that base form is 0 since the function does this check itself already
  53. ; Info: Game is saving location's seen data to save game. The data is NULL.
  54. ; Cause: Game doesn't check for null pointer
  55. ; TESObjectCELL * v3 = ..
  56. ; v5 = BaseExtraList::GetSeenData_40D980(&v3->extraData);
  57. ; result = (void *)(*((int (__thiscall **)(_DWORD, _DWORD))*v5 + 1))(v5, v2); // <-- v5 can be null! but not checked
  58. ; Solution: Only solution seems to be temporarily creating an empty IntSeenData and writing this to stream instead.
  59. ; Info: BSFixedString::Set is called with NULL argument.
  60. ; Solution: Ignore call when NULL argument. Not really a solution :P probably better than crashing though.
  61. ; Info: This crash happens because StrLen crash was prevented.
  62. ; Solution: Skip over it.
  63. SkipStrLenCrash=1
  64. ; Info: This crash happens because unknown reasons during loading. Something to do with behavior graph.
  65. ; Address: C27A8F
  66. ; Solution: Don't know, trying to let game think the value is 0 and see what happens.
  67. bhvGraphUpdateLoad=1
  68. ; Info: Crash happens during loading, no idea. Might be related to rendering.
  69. ; Solution: Tried patch something but it probably doesn't work.
  70. ; Info: Incompatible skeleton, but could be something else too.
  71. ; Solution: No solution from here, but since it's going to crash anyway we could at least
  72. ; warn user about possible incompatible skeleton and let them fix it. Shows messagebox
  73. ; Info: Crash, it's function array and index goes out of bounds which causes it to call invalid address.
  74. ; Solution: Check index before calling.
  75. IndexError1=1
  76. ; Info: Crash happens in 'MovementPlannerAgentWarp' function, unknown what it does. LookupFormById returns
  77. ; NULL and game does not check or expect this to happen.
  78. ; Solution: Game has a check for if returned isn't actor it sets 0 as value, we will do same if NULL is returned.
  79. ; Info: Crash happens in DDB0A0, seems to be used in some havok animated object's vtables.
  80. ; Normally these crashes are fixed by aligning allocated memory with 16 bytes. But
  81. ; this one isn't because it can be used on static memory locations which aren't using
  82. ; Skyrim's allocator at all, this means that memory isn't guaranteed to be 16 byte aligned.
  83. ; Solution: Use movups instruction instead of movaps.
  84. ; Info: Weird crash with NULL ptr in TESWorldSpace::GetCellByCoordMask_4375D0, don't know why it happens.
  85. ; Solution: return 0 if this crash would happen.
  86. ; Result: Haven't had this crash since, but it's rare anyway so it could be coincidence.
  87. ; Info: Crash when trying to do: v14 = MagicItem::unk_406C70(a3)->properties.projectile;
  88. ; This 406C70 function is something like 'GetMainMagicEffect'. Sometimes though it may return
  89. ; NULL and in 90% of places the game expects this and checks for NULL result, this patch will
  90. ; Address: 7E39EC, 657677, 6577D5, 65FEEC, 8127CF
  91. ; Solution: Check for NULL and skip (depends on location) if it is.
  92. ; Info: Crash when game searches node 'NPC COM [COM ]' on actor but the node was not found. This is unexpected
  93. ; for game because it uses the result without checking for NULL. This whole thing has something to do
  94. ; with mounting. The function that does this whole thing is present in 'StopMountCameraHandler' and
  95. ; 'MountInteraction' vtable. Also it seems that this has something to do with updating position.
  96. ; More info: Was reported that this could happen if non-humanoid tries to mount a horse. This is a rather specific
  97. ; error with a mod. Instead we will show error message to user when this happens so they can
  98. ; Address: 6E7F85
  99. ; Solution: Check for NULL and if it is NULL then use base node of actor instead of this. It's fine because
  100. ; Solution2: Show error message and crash after.
  101. MountNodeWarn=1
  102. ; Info: Crash when game is trying to setup foot IK but there's a problem. Real cause is unknown but for me.
  103. ; So we will display a message box when this crash happens. Seems related to the
  104. ; StrCmp crash in BF2FB3, maybe. Try reducing the amount of installed animations.
  105. ; Solution: No solution from here, display warning with helpful tips.
  106. ; Info: Crash happens when rendering and saving. I think this is when it renders the save game image.
  107. ; {
  108. ; v9 = *(v8 + 8); // <- *(v8 + 8) is null
  109. ; v9 = 0;
  110. ; v10 = *(v9 + 140) * *(a2 + 4) // <- crash because null
  111. ; + *(v9 + 144) * *(a2 + 8);
  112. ; }
  113. ; Solution: We will skip this if block when *(v8 + 8) is null, as if v8 was null.
  114. ; Info: Crash was reported as casting spell. Only happens sometimes. Happens in movement controller.
  115. ; Address: 76636B
  116. ; Solution: This happens in a for loop and it happens in if clause. We can skip if this crash would happen.
  117. ; Info: Crash when saving game and trying to render (possibly save game image again?). It's trying to get
  118. ; if ((*a2 + 76)(a2, a1)) // a2 is null
  119. ; *(0x1BA9344) = a1;
  120. ; }
  121. ; {
  122. ; *(0x1BA9344) = 0;
  123. ; Address: CAF9F7
  124. ; Solution: Skip function call and set return value to false so we don't have to use the NULL value.
  125. ; Info: Crash when game tries to get loaded node but it is set to NULL. Only ever seen this on two people.
  126. ; It is most likely actually related to corrupted mesh being unable to be loaded and game does not expect it.
  127. ; v2 = node->(*(vtable+0x14))(); // <- node is NULL
  128. ; if(v2) { *((int*)(v2 + 212)) = 0; } // <- we can skip this part since it has a check anyway
  129. ; Solution: Real solution would be to find the broken mesh and remove it. So lets notify user instead of ignoring this part.
  130. ; Enable one of the following, ignore problem and try to continue or show message box with object reference form ID and form Type.
  131. NullLoadedNodeNotify=1
  132. ; Info: Crash in GarbageCollector::Add when actor argument's base form is NULL. Game does not check this, when in
  133. ; some other places it does check for this possibility.
  134. NullActorBaseForm=1
  135. ; Info: Crash when modifying actor value but the pointer is bad, possibly due to actor being invalid. This happens often
  136. ; when script engine is lagged and spells want to modify actor values a lot.
  137. AVSetCrash=1
  138. ; Info: If your scripts use more than 65535 different strings then the save game will be corrupt and not possible to load.
  139. ; This fixes it by changing the save file format slightly if string count is higher than 65520. That means if you
  140. ; have this option enabled and your save game would have become corrupt it changes format instead and vanilla game
  141. ; or save game tools will not be able to open it! Opposite is true as well, if the count goes below 65520 after
  142. ; and you save again then the format reverts to vanilla.
  143. ; TLDR: Fix for https://forums.nexusmods.com/index.php?/topic/3924850-corrupt-saves-strcount-0xffff-ctd-on-load/
  144. ; Address: Around 30 different parts of code had to be patched.
  145. ; Info: Warn if SKSE memory patch is not active. This checks if default heap size is 256 or less and warns if you try to
  146. ; click New, Continue or Load in main menu. Still lets you play the game, just shows a warning.
  147. ; Info: If AlignHeapAllocate is disabled by user then fix that one movaps crash manually. There's no downside to having this enabled.
  148. FixMovApsManuallyIfAlignedAllocateIsDisabled=1
  149. ; Info: Overwrite array allocator directly when UseOSAllocators is set to 1. Don't understand the code enough yet to
  150. ; say if it's safe or not. At this point it's just here for testing.
  151. ; Info: Player's NiNode (not necessarily same as loaded node) is NULL while drawing world.
  152. NullPlayerNode=1
  153. ; Info: Function TESObjectREFR::CanBeMoved_4D9CF0 is called on an object reference that has NULL base form. This is not expected
  154. ; and will crash. We will instead return false from that function if that's the case. The problem is most likely larger than
  155. ; just this, if you prefer to crash instead disable it.
  156. NullBaseFormMove=1
  157. ; Info: Game tries to iterate child nodes of a NiAVObject but it's possible that the target is not a NiNode and can't have child nodes.
  158. ; v26 = v22->vtable->sub_5EADD0(v22); // Returns 'this' if v22 is a NiNode and returns 'NULL' if not.
  159. ; for ( i = 0; i < v26->children.emptyRunStart; ++i ) // crash because v26 is NULL.
  160. NullRefNode=1
  161. ; Info: Something is done with outfit of NPC, but one or more entry is NULL and game crashes.
  162. NullOutfitEntry=1
  163. ; Info: Actor is being deleted and base form is NULL.
  164. ActorDeleteNullBase=1
  165. ; Info: Does two things:
  166. ; 2. If the game crashes while reading binary data stream (e.g. NIF file but could be others too) then show message box listing
  167. ; This can be helpful to track down a corrupted NIF file.
  168. ; Info: When the game fails to create texture in memory should we display a warning and exit game? Recommended yes because you will
  169. ; see purple textures couple of seconds and then the game will crash anyway since it's not expected for this to be a NULL value.
  170. ; Info: Something is done with face gen animation on BSFaceGenNiNode but the parent node is NULL which is unexpected.
  171. NullParentNode=1
  172. ; Info: For debugging purposes, on game startup run allocator benchmark and write results to 'AllocatorBenchmark.txt' in Skyrim root
  173. ; directory. This compares vanilla, aligned vanilla, malloc, aligned_malloc and custom memory block implementation. When you reach
  174. ; main menu the game will start the test, wait for a message box to say the test is completed, then close game and disable this option.
  175. ; Info: How many objects to allocate and free for each size (8, 12 and 16).
  176. ; Info: How many times to run each test.
  177. ; Info: How many threads to run concurrently. Most accurate is only running one thread, although you can also try 2 to see the performance
  178. ThreadsAllocatorBenchmark=1
  179. ; Info: Enable custom block allocator for small sizes. May help with memory fragmentation problem. This option does nothing if UseOSAllocators
  180. CustomMemoryBlock=0
  181. ; Info: Set total megabytes allocated for the custom block allocators. This amount is sensibly divided between each block.
  182. ; Has no effect if CustomMemoryBlock is not enabled. The more you allocate here the less memory you have for other stuff!
  183. ; Info: Show usage of each memory block in per cent when you open console. Has no effect if CustomMemoryBlock is not enabled.
  184. ; This can help you tweak the CustomMemoryBlockTotalSizeMb value.
  185. ; Info: Fixes two crashes specific to Enderal mod. Seems like something to do with havok.
  186. EnderalSpecific=1
  187. ; Info: Active effect list of actors is not thread safe but accessed and modified from multiple threads, this will add mutex to each actor's
  188. FixUnsafeEffectList=1
  189. ; Info: Game crashes when actor's combat style form is NULL for some reason. Warn the user and try to display the actor's reference and base ID.
  190. WarnNullCombatStyle=1
  191. ; Info: Set OS update frequency to 1 millisecond (regular is around 16) and replace GetTickCount with timeGetTime. This is for debug only! Don't use.
  192. HighFrequencyOSTimer=0
  193. ; Info: Make game's update timer more accurate. This is for debug only! Don't use.

Update: Bethesda has offered a solution to game crashing caused by the recent PC Skyrim patch.

This is the maximum amount of memory the VM will allocate in total for stack frames. And the only solution was to remove the worst offenders from my load order.oh and running Safety Load has helped me immeasurably too, but that's another topic. Nothing to do with memory of Skyrim itself. Tamil krishnan devotional songs free download. RCRN infos are outdated.

Original story: PC Skyrim has been patched, and the RAM-boosting, crash-preventing, third-party Large Address Aware (LAA) mode outlawed.

PC Skyrim, following the 18MB patch, now runs only through Steam. The LAA mode, which required some executable-file manipulation, no longer works.

The problem being that the LAA mode enabled PCs to use more than 2GB RAM, which not only helped stability, but boosted performance of the core game and the numerous mods applied on top.

The ball's in Bethesda's court.

The Digital Foundry Skyrim face-off assessed all three versions of Skyrim - PC, PS3, Xbox 360 - to find out which is best.
