Alright so I started up Skyrim for the first time in a while, default set on Ultra High /w My assorted mods, now for the first 3 days, it was running like complete butter, 60FPS solid, perfect..

(ex. Unofficial Skyrim Patch, Immersive Weapons/Armor, FXAA Post Process Injector, Pure Waters, Midas Magic, High res texture).

But after 2 days, It began to stutter heavily, then it went away, then it continued to get worse, tiny flickers of textures here and there, until the point where it was unplayable and I would get massive stutter and flicker.

so I disabled all my mods, everything except just bare skyrim, Still flicker and stutter. So then I tried downloading the 60ghz Skyrim Stuttering Fix off of the nexus, still nothing. I even reinstalled Skyrim itself.

I've googled my heart out, since I really would like to enjoy Skyrim, but It seems I cannot fix this problem.

If you could offer any insight on how I could fix this, I would be in your debt forever. Thanks.

Unofficial Oblivion Patch?

Skyrim* haha, Sorry, not sure why I put that.

Flicker and stutter; it's looks like it's a hardware/graphic card problem. Did you install new/beta drivers or something?

As "UserNamesAreOverrated" say the oblivion patch must be a write mistake from you.

Also, just in case it's not obvious, when troubleshooting Skyrim, do so in vanilla (non-modded) mode. Only re-enable mods when vanilla mode is working !!!!! (Very important)

Do you have SSAA or something forced accidentally from NVidia CP?

Try to disable to SLI mode in your control panel and watch if you see any difference.

(because i don't know if SLI is indeed working correctly.)

Try to play with vsync on and off and see if it makes any difference.

My recommendation do not use skyrim in-game AA at all, turn it off, force it through your GPU. (Do the same with AF)

What resolution do you play. ???? Try yo lower your resolution a bit.

Bethesda released the “4gb patch”, but this doesn’t necessarily mean your system will automatically use more than 4gb of RAM!

So, in your case:

Open your Skyrim.ini, usually located at the path: C:\Users\youruser\Documents\My Games\Skyrim and search for: iMaxAllocatedMemoryBytes=*******

if you have 8GB or 16gb of ram -> iMaxAllocatedMemoryBytes=4000000000

Try those out - on vanilla skyrim and do step by step the above changes. (i would suggesting to clear your saves and configuration files and begin from scratch.)

The are many people like you on the net with the same problems, and Nvidia SLI configuration as well. !!!!

and something else... see if some program(s) interfering with your game and always play with your Antivirus disabled. !!!!!

that's from steam support:

" Any applications running in the background may negatively affect your games or Steam itself. Certain applications can lead to more serious issues such as limited connectivity and game crashes. It is highly recommended that you close all background applications before launching Steam to ensure the best performance and stability. After you are done playing, feel free to re-enable these applications."

No, don't touch that stuff at all. That does not do what anyone thinks it does. Skyrim will use up to 4 GB of RAM if it can by default. No tweaking, flipping of flags, whatever is needed at all.

Nope, SSAA isn't toggled on, and regarding the AF and AA through CP, I can use its AF but not AA, as it says its application controlled and completely gray'd out?

I only say that because some people have found that the game is about 20% smoother when the properly memory value is set!

Again, don't touch it. That's for the Papyrus virtual machine and shouldn't be touched at all.

Well so far I disabled all mods, made it completely vanilla, turned off all AA and AF, Lowered resolution, and still major stutter and even more flicker.

Not sure how to toggle Anti-Aliasing through the Nvdia Control panel though, It seemed to locked it for Skyrim as its "application controlled". Looks like my only hope is too see if SLI is working properly.

Thanks for the all the tips though, gives me hope

ok it must be driver related then, so try to play first without AA enabled.

you can check it with CPU-Z too...

okay my friend....

What do ya' mean?

Yeah think I solved it, It seems Skyrim's AA for whatever reason just really messes me up, seems much more stable with out it, and I also enabled V-Sync. Thanks for all your help guys!

CPU-Z It's a system hardware monitoring tool. And it's free. http://www.cpuid.com/softwares/cpu-z.html

Nice you did it....

You can try 2 or 4X AA and add FXAA, that seems to have no hit on performance. Just make sure your Nvidia control panel is not trying to run AA at the same time. In fact, the Nvidia AA is known to cause weirdness in this game for some.
