Last night I noticed Skyrim FPS drop from 60 to 30-40. I haven't checked FPS for quite some time, so I am not sure what's behind, although I suspect a few.
- Lots of vegetation: I happened to play in the middle of woods and bushes. When I entered into a cave right next, FPS jumped up back to 60. But previously when I was playing in similar environment, I didn't feel big change in FPS, although I didn't check actual reading.
- MODs: I downloaded 11 MODs. They are like Dragonfalls Manor, Dragonbone Armor, Wild sound, Hi-res snow, etc... nothing grande. Can any MOD affect FPS?
Here is my spec
DDR3 8 GB 1333MHz
EVGA GTX 560 Ti 448 @840 MHz 295.73 WHQL
Windows 7 Ultimate 64 bit
1920 x 1080 DVI
Ultra (GTX 570 Recommended setup)
GPU temp was steady under 60C, so the heat was not an issue. I've been playing hi-res since it was available, and didn't have (at least didn't notice) tje FPS issue. I will try to run it without MODs tonight.
