I reinstalled skyrim and stuffed it full of mods. It runs incredibly well off my 760... for 10 minutes. I've read some other threads about gpu slowdowns, but it seems that they're mainly caused by GPU overheating, but that's not the case here. I use Afterburner's on screen display to keep track of a few vitals, including temp and GPU usage, and the temperature never goes beyond 60 (anyway, I'd hear it before it became an issue). The interesting thing is this: the GPU usage begins at >100% because I increased my TDP via Afterburner. For a while it stays there. But once I start to notice the fps slowdown and check the GPU usage, it's dropped to 30-50%. It's like it decides to just fall asleep. It isn't a memory issue either because I keep track of that too and I've changed my settings so that it never hits the VRAM limit. Has anyone seen this issue before? Any ideas on how to fix this? As a side note, this is purely a Skyrim issue. FO4 does not have this problem and neither does any other game I've played.
