Hello, sorry for your time.
I have a small issue with FH4. I have played for a long in FH4 with 60+ fps. And a few days ago fps became about 25-40 fps at different levels of graphics. Also load of GPU ~100% (before that it was about 70%). Could you give some advices. Thanks!
My specs:
I7 2600
12 gb ram
Gtx 970
Sorry for my English 
I know that Winter takes a stronger toll on my GPU than any other season. Could be that.
