Specs:

Video Card: GTX 680 2GB VRAM
CPU: i7 3770k
System Ram: 4GB

I have a Solid State Drive but the game is installed on the other drive which isn't SSD.

--------------------------------------------------------------------------------------------------------

Problem:

The Game used to run nicely. Suggested settings were "Ultra."

I installed a few mods and the High Res Pack by Bethesda. Things were fine.

I decided to install the Flora Overhaul, FXAA injector and Nvdia inspector with suggested settings. The game started stuttering and freezing.

I uninstalled everything. I re-installed (vanilla). The game still freezes at times. You can see an example below (it is particularly evident at about 0:44-0:47):

Possible things to keep in mind:



My RAM could be insufficient to run the game. This seems odd however, since the game used to run fine before. This system should handle the vanilla game fine in theory.

Could it be corrupt saves? My current save file is about 10 meg.

Let me know what it is.

What does Nvidia Inspector do? It may have something to do with how your GPU is detecting high settings instead of ultra. I do not know much about Nvidia stuff so that is why I ask.

Actually, disregard the "Ultra settings" thing it was a mistake I'd made. I also uninstalled the inspector program.

Ok, I apologise for re-bumping this but I have managed to find the problem. Nvidia inspector stores the game's settings even after I uninstalled it. I had to reset the game's global settings in Nvidia's control panel. This might (or more likely might not) be useful to someone else who has the same problem. I am not sure which setting in inspector resulted in the freezing/stutter you see above, but I suspect even the Flora mod will work now.

The Nvidia Inspector settings were found at this page:

Since I have recently built this computer and it is pretty beefy as far as gaming workstations go, I'd advise anyone to be careful with those settings (I guess). It's the second time I have problem with Inspector settings so I personally will leave those alone for now.

I am a AMD user, but I have had a very similar issue before (More like "reverse issue"). In Fallout 3 on my old PC, it defaults to medium settings but when I got the ATI Trays tool program, it detected ultra high quality for some reason (Core 2 Duo, Radeon HD 6670). It was strange.

Multi Display Power Saver? If so, even with 32GB RAM, 2 590s (even if the whole game is played via a RAMDisk), Skyrim (among other games) will stutter when transitioning from a menu back to 'game time', having throttled down your clock speeds and boosting 'em back up to accommodate the game unless you add it to the list of full 3D applications. This can also happen if the cell/worldspace you're in happens to be really dark as the card will perceive that it can cool off and take a break.

Just a theory, but...
