Skyrim Memory Patch - fixing ILS, uGrids CTD, freezes

[KuroTenshi]

For the people running Dance of Death, are you also running a perk overhaul ? I had a lot of issues with this mod up until I realized that I had to turn off the perk flag in the MCM whilst using TTRSO.

Dance of Death interacts correctly with Skyrim Unleashed and Sperg. I don't have problems so I think Dance of The Death is only part of the problem. Before, when my saves where corrupted (on an instable Skyrim), it's true that removing Dance of The Death could help. But It could be too Skytest Realistic Predators, and many others.

A load order that works for me with nearly everything improved (even at ugrids 11 (not tested above)) :

You can quietly add ENB and textures packs (I used compressed 1024*1024 textures for objects, 512*512 for small objects and 2048*2048 with Parallax for landcapes). Packs by Cabal (AMidianBorn ...) or Kobayashi (clothes) are great (very beautiful while being optimized). Book Covers Skyrim is cool for books and paper. For hair, Natural Apachii Retexture and Superior Lore Hair are good. I am using of course UNP body and Better Male Body and Faces. Using everything, I hit my 2gb of VRAM pic anyway.

I replaced the High Res Texture Pack with this : http://www.nexusmods.com/skyrim/mods/9957/?

I cleaned Skyrim.esm, Dawnguard.esm, HeathFire.esm and DragonBorn.esm too.

@Wojtab

Check back on page 5 of this thread I think you may find this has been done, although I do like your version

Thanks for good opinion, your version from 5th page is similar, but it has one mistake there:

Code: Select all

SafeWrite32(0x00687e87+2, MemBlock1+256);

and it should be:

Code: Select all

SafeWrite32(0x00687e87+2, MemBlock1+MemBlock2*1048576);

You are assuming that MemBlock2 is always equal to 256MB. If someone set eg. block1 to 512MB and block2 to 1024MB bad things could happen.

@KuroTenshi

I was unaware they were compatible I just know I had to tick off a flag in my MCM for dance of death to resolve some small issues, personally I have no problem with it.

According to my MO i have 370 mods active of which 240 are esp's and with the SKSE patch I have no problems, I have however been encountering some issues with the SSME patch so I will be switching away from that.

Actually I am not sure you are correct, that code was provided by Sheson (check page 6), the first block allocation according to code by default is already 512Mb, in hex 0x200, so my code defaults the first block to 256 and adds the hidden 256 that a user would not normally see. The two blocks should be completely independent, in your code you just showed changing one will change both, this is not a good idea.

For example in my code i can set 512/1024 split, if i set that in yours the first block would try and assign 1.5gb

EDIT: Ahhh i see what has happened, you may have read my code as being one variable for two memory blocks, its actually two independent memory blocks, Memblock1 and Memblock2, they are configurable as MB in the ini file and the code adjusts them to the correct values, trust me they work and have worked for many many people for over a week.

I also point you to ...

How it works

When tesv.exe is started it allocates two 256MB blocks of memory. When the first block gets full, the engine will allocate more blocks. This can cause the known troubles. Thankfully, by telling the engine to request a bigger block from the start it magically makes use of it without any further ado. This isn't the case with the second block. Thankfully again, the second block does not fill up as quickly and once it is full the engine does not trip over itself when allocating more blocks.

In your code you say the default first block is 512Mb, this is actually not true it is 256Mb, as shown in the quote above, there is a hidden 256Mb a user would not usually see, you can check your own or any of the many VMMaps throughout this thread.

[Wojtab]

I see where I made a mistake, I'm not really experienced in memory blocks(working on them for the first time) and I thought that second block is taken from a first block. I tested it using only 256MB on second block, and there is 256MB taken from the first, so I assumed wrongly. Oh well, it has made mine skyrim better, so I accomplished the goal.

Mate, I had issues with it too the whole things is pretty tricky to wrap the old head around initially, if you look at my post on 5, you will see I made a stack of edits on my post to get it right, the original was a mess lol, thankfully a lot of cool people here who helped out and pointed me in the right direction. I am glad your game is better

Hi,
With this memory patch I am able to run the enbhost.exe process all the way up to 4GB. At that point, TESV.exe memory starts increasing rapidly until I finally get a CTD. Way back in the ENB 0.200 thread Boris said this:

Oyama
VadersApp
Enbhost.exe is process which mod start when ReduceSystemMemoryUsage=true, it is garbage collector for memory. In future i probably make several copies of the same process to cover greater memory range. As i don't have hardware for testing 64 bit, i did this as 32 bit application, so only 4 gb memory available for each enbhost.exe running. This means that all unused memory allocated in enbhost.exe and when required, it send back to game. Skyrim 4 gb + enbhost 4 gb.

Boris, would it be possible for you to implement a second enbhost.exe with an addition 4GB?
Thanks!

Are you sure it's not the bug in the scripts or something else which leads to memory leaks? Because nobody yet had this issue before, even when EnableCompression=false. Of course i can do any number of enbhost.exe processes, but first i want to be sure it's not the bug.

[number6]

I can't be sure if it's a memory leak, but I don't think so. enbhost.exe stays under 4GB unless I start increasing ugridstoload past 13 Sound high, but with this patch even 13 is stable. When ugridstoload=15 then enbhost.exe uses a max of ~4GB at which point TESV.exe starts to use more memory rapidly. If I don't go over 13 then TESV.exe stays around 1.5GB and enbhost.exe is around 3.7GB.

I think before this patch, back when 0.200 was out, nobody could push their setup even close to this so the limit could never be reached. But now things are different .

@Daetarek

What problems have you had with using SSME?

Since I didn't see any repsponses, I'll ask about the differences in SSME again (sorry for a little spam):

Both sheson's original (skse_steam_loader.dll) method and Queued's (d3dx9_42.dll) variant both use a dynamic library to inject the modified code to patch TESV.exe. So, I have assumed that if I see that the mem block 1 value has changed as expected, then there is otherwise no difference in how Skyrim will behave after that, regardless of which method is used.

I came to that conclusion because as far as I know, both methods make no further changes to or interact with TESV.exe after the three lines code are patched.

Can anyone confirm this or otherwise explain how they may effect TESV.exe differently?

@sheson

Thanks for the advice on hunting down mods to solve my remaining CTD issues. You're preaching to choir on the recommendation of Mod Organizer - I don't know what I'd do without it. I try very hard to only use texture replacement / plugin-based with a proven track record, but yeah, maybe there's something in there - though the vast majority are same as SR:LE (but lighter on the scripted mods end), and so many people are reporting great success using that lineup of mods/textures.

Anyhow, as I recommended to Nearox I'm going to cut my whole mod list out of the equation completely and just run 100% vanilla Skyrim tests, straight from Steam, with only ENBoost & SSME (unless I hear clear confirmation of reasons not to use SSME, in which case I'll have to do vanilla + SKSE).
