Gradual FPS Loss Using ENB - halp

[Bloodwardena]

Heyhey.

So in my pursuit of refurbishing Skyrim's aesthetics according to my preferences I've picked Bleak Enb.

When I first start the game with the ENB UseEffect ticked everything is perfect for the first... half a minute. Smooth 60 fps, with little dips here and there in stressful areas. But then after about 40 seconds it drops into the low 50s, then eventually 40s, and then the 30s. I feel like my pc and setup is more than capable of running the game at 45-60 fps with the ENB on constantly but for some reason it just keeps degrading. I can temporarily fix it by unticking UseEffect in the game and then reticking it some minutes later. Then it is smooth once again for a minute before deteriorating again.

Can anybody explain what could be going wrong here? :x I've tried nearly all the tricks. Tried messing with the enblocal.ini, disabled steam overlay, used the correct version of ENB binaries(279) but to no avail. I also have the SKSE memory tweak, of course.... any help would be appreciated. D: thank you

Hello,

• If you're using win8 -10 + a GPU with more than 4GB VRAM + a heavily modded game and experiencing stuttering, random freezes or / and FPS drops, this may occur when the VRAM usage exceeds 4GB, read here for more details.
• Make sure your specs can handle the mods you're using. Eventually deactivate some heavy mods, 2k textures, and start a new game for purpose testing.
• Make sure your ENB is configured correctly. Install also ENBOOST, (ENB haxx)
• Skyrim performance monitor.
• Shut down background programs such as intellipoint, fan manager, etc... Need a tool to manage GPU fan speed that works with ENB ? You may try Afterburner, (tested)

Good luck.

For some reason the skyrim performance monitor is making my game crash after a minute or so. I managed to snatch a single screenshot

Some ideas on the fly : what are your specs ? Graphic card + VRAM, OS, RAM, etc...

• Verify gamecache.
• GPU 86% : the more you're using your GPU, the more unstable your game. You may try other things such as deactivating temporarilly your 2k textures packs and graphic resources demanding plugins, effects, grass, flora, ENB, etc... May be your specs can't handle what you're asking.
• Reset your inis : Backup your ini files and delete the files. Skyrim.ini / SkyrimCustom.ini / SkyrimPrefs.ini found in C:\Users\User\Documents\My Games\Skyrim then use your vanilla launcher to autodetect and use best settings for your computer.
• You may also try without mods and eventually start a new game. This will ensure to not use your savegame and your mods. If the issue occurs again, you may have a problem with your game or your hardware / settings. Make sure in the GPU control pannel you're using, the settings are to let skyrim manage by default.
• Ensure the HDD / SSD where the game is installed and also operating system has enough space for the swap file, is healthy and defragmented.
• Are you using overclocking ? Make sure to reset things by default.
• Are you using Ugrid to load ? Same as above.
• Make some search if not already done, as there are other thread like this one that may help you.

Good luck.

Phew, so much effort just to bang Bijing Warmaidens using OSex...


My card's GeForce GTX 970m, 3072MB GDDR5

Running Windows 10.

8GB RAM.

i7-6700HQ, 2.60 GhZ cores


While I still have to go through most of those steps one thing is confusing me here. Namely how come my rig couldn't possibly handle this if it gives me nice clean 60 fps at the start? If my laptop couldn't handle the settings and mods im running right now wouldn't the FPS be horrendous from the start? And how come it says in that screenshot that my GPU is 86% used if the green part says that only 730mb of my vram is used? That would only be a quarter of my 3GB GPU... no?

I'm no techie, I just want to know how these things work. D: I hardly think my 970m is used by any other processes in the background, and my game doesn't seem even close to hitting those 4gb memory caps win10 imposes on directx9 when playing skyrim as far as I know.

Thank you for all your suggestions, by the way, I really appreciate it. I've been trying to deal with my skyrim crashing ever since I started modding(pretty much as soon as the game was released heh) and I haven't really openly asked for help until now.

• if you're using much GPU, the game may ask too much with ini settings, resolution, graphic settings, etc. If you don't use much VRAM, then your game doesn't need more. You may try focus on graphic settings, ENB, inis, etc.. Make some backup, reset the files and try. There is a difference between loading textures and applying graphic settings, like there's also a difference between CPU usage and RAM usage. I'm not an expert, but hey, this is what seem to indicate your screenshot.
• Deactivate your ENB and test. If it worked, you may use this guide to check your settings.
• Backup your ini files and delete the files. Skyrim.ini / SkyrimCustom.ini / SkyrimPrefs.ini found in C:\Users\User\Documents\My Games\Skyrim then use your vanilla launcher to autodetect and use best settings for your computer. STEP INI tweaking wiki.

Good luck and come back to tell if something worked or not :wink:

Well, I tried most of what has been suggested and here's what I've found out so far:

Most of my crashes as well as the constant decay of fps were caused by a poorly optimised enblocal.ini, possibly due to the limitations imposed on DX9 by win10. I managed to get my game more or less stable(although I still suffer from mysterious crashes) but I haven't managed to fix the fps decay. Sort of.

It does not occur when I don't use an ENb, however, so it can't possibly be mod related or texture related or whatever. Neither do I get fps decay if I disable both, ambient occlusion and depth of field. Stable fps all around, except for those heavy places that drop my fps regardless of whether I use enb or not, like solitude or some bandit fort. Not sure why those screw my fps. I can have fine fps in some places despite there being a ton of spawns, like some forsworn camps.

The quality is still nice with those two options disabled, albeit I do miss them. Any clue why the fps could be degrading? Is my vram somehow clogging?

Read here about stuttering / fps issues.

• Read Jones177 post in this topic about vsync.
• Ensure If using windows 10, set ExpandSystemMemoryX64=false in ENBlocal.ini
• <It does not occur when I don't use an ENB> try another ENB that require less resources and try an ENB manager.
• you may try crash fixes with the UseOSAllocators=1
• Have you installed ENBOOST ?
