Hello,
First of all, sorry for my English.
I was searching for the possible solution for a long time, but couldn't find anything similar to my problem.
Recently I came back to Crysis 2. It ran smoothly for some time (40+ fps everywhere) but then, 3 days ago, it dropped to ~20. I tried to figure out what the problem was, so I checked the GPU usage in EVGA Precision and it was low - 60% average. Interestingly, when the fps was low, so was the gpu usage (similarly - high fps - high gpu usage).
Then I logged on my secondary OS, wchich I hadn't touched for several months - the game was running smoothly as it used to.
MY SPEC:
i5 661 @ 4,2 Ghz
Gigabyte GTX 460 1GB
4 GB RAM 1600 mhz
Seasonic 620 W
Asrock P55 Deluxe 3
WHAT I DID BEFORE THE PROBLEM HAPPENED:
Updated the nvidia drivers (from 290.53 to 301.42). However, later I tried to reroll the drivers (manually and using Driver Sweeper) to 290.53 and 296.10, but it didn't help. However, after I updated to 301.42 for the first time, it worked fine for 1 day.
Swapped the PCI-e slot (I was cleaning the computer)
WHAT I TRIED TO DO AFTER:
Reseting the BIOS settings
Playing with NVIDIA control panel (single performance mode, and performance mode)
Tweaking some services (nothing important)
Downclocking my CPU to stock speed and overclocking it back
None of this helped.
I know it LOOKS like a CPU bottleneck, but how can it be one, if on the other OS it runs ok?
I think it must be software related.
Should I reinstall Windows?
Thanks for help
