2GB VRAM with heavily modded Skyrim: Has anybody had issues? - Page 8

post #71 of 84
Hi to all, I know this is an old thread but hopefully 1 or 2 people still follow it.

I wanted to ask if anyone has had experience with a GTX 690 4GB with a modding Skyrim???
I built my rig at the start of the year and I "assumed" a 690 would be overkill for 1080p on Skyrim, but I'm pretty p**sed off to see that it isn't! I'm getting massive stuttering when turning and about 1 CTD every 2 hours in game!
I know the 690 isn't a true 4GB card but I still thought it would be able to handle it cryingsmiley.gif
And yes I do regret buying the 690 now.

Well anyway, if anybody still follows this and has had or heard of 690 issues, please let me know.


Thanks to all

yes, it has 2GB mirrored. lower some settings like AA maybe.

edit: ask here, too . . .

might be driver issue.

since its 4gb are mirrored i bet you are using too much vram
there are people showing videos/pictures about skyrim modded at 1080p using 2.5 to 3gb with hd textures pack
like rd09 said try to reduce aa
also the crashes can be caused by hitting 3.1 ram(not vram) usage(skyrim engine crashes at that mark)

I have a 2GB GTX 670, and I'm able to run around 90+ mods without issue. I occasionally experience crashes if I install a mod that interferes with another mod though. Also, with these mods, I comfortably sit around the 45-60+ FPS mark. It tends to dip when I'm in an area with thick flora.

I have 7770x2 1gb VRAM versions of the card. SKYRIM modded with full 2k textures 8msaa 16AF fxaa smaa Vsync enabled 4k shadows and such... No CTDs 60FPS and loving it on an AMD FX 8350. So anyone with 670 and up or AMD versions 78xx and 79xx wont have hardware problems, at least GPU wise; CPU maybe. And as the above poster mentioned it is usually A mod that creates the issue.

Doesn't matter how many mods you have. Unless you have heavy hi-res texture packs that push the VRAM usage to over 2GB, it doesn't matter. The poster should turn the AA down a bit and use EVGA Precision X to see how much VRAM his GPU is using. Sometimes the mods are simply all over the place and do a non proper usage of the system resources. By rearranging the them, he could see an improvement.

About half my mod list consists of high res texture packs, whether it be for insects or distant landscapes. But yeah, you do make a good point about VRAM. It would generally be a good idea to monitor that.

Except if that were the case I would be crashing all the time. With a sound mid level system it is more complicated than a simple VRAM use. Textures can be offloaded to system RAM, which is what mine does ( total SKYRIM system ram for me is generally 5-6gb ). Most issues with BSOD can be attributed to conflicting mods, wrong mod order, and in some cases instable computer setup or hardware errors.

Well I know ALL my VRAM is being allocated to Skyrim but how much it's actually using is probably slightly lower. I have 83 mods installed and around 15 of those are HD texture packs, bit extreme I know, I have dropped a few now. I've also turned AA and CSAA down a little.
I have since uninstalled ALL mods and reinstalled them in a better order, but it hasn't helped really =( Think the only way I'm gonna be able to fix it is a clean install, which I don't want to do as I've pumped over 150hours into my current character in the past few weeks. If it gets worse I might have to though :'-(

I'm not hitting the 3.2GB RAM limit as I have the latest ENB series installed which uses ENBoost so my RAM usage is actually only around 600MB to 1GB.

My fps never drops below 60 but I do still get the stuttering in Whiterun but I do have Beautiful Whiterun mod installed, also Riften, Windhelm and in high flora areas.

It's definitely not my CPU. I think your right about the mod issue though.

I'm curious, how are you using 5-6GB of system RAM when Skyrim has a 3.2GB limit???

Cheers guys

Your discrete GPU doesn't actually use your system RAM for video games. There are very very few programs that will allow your GPU to use your system RAM. I also doubt you're using 5-6GB of VRAM even for a heavily modded Skyrim. The most I've seen being used was was around 4GB with crazy ass triple display setup at 5760x1080. If you use 5GB, you must have some ridiculous 4K texture mods with 8x MSAA. Even that would probably not be enough unless the creator of the mod did a complete screwjob at compressing the textures. Unless I'm missing something, dedicated GPU VRAM and system RAM are independent of each other and cannot be used together. If it weren't the case, nobody would complain about 2GB cards as anyone with an 8GB system could share the system memory with the card.

Pretty sure there's a mod to break the VRAM limit by modifying the game code but I'm not 100% certain. Also, has your game been doing that recently or it started a while ago? If it started recently, you can isolate the issue by uninstalling several mods. You're not forced to delete your save either, just back it up, make a list of the essential mods for it and voila!
