Well ever since i started playing.. about a month or more ago ive always had 60fps on all high settings and it never moved up or down was just capped at all times.. now after this most recent update My fps has now dropped to about 25-30 mid game.. it goes 60 for first little while then will eventually settle at 25-30. I dont know if others are noticing a problem. But if anyone has any advice it would be helpful. Also i have avast professional and i clean my comp regularly so these arent problems

Sounds interesting.

Try reading through this thread and perhaps give some of those solutions a shot:

It has been happening for a lot of us off and on for the last few patches.

Its not microstuttering.. the fps has just dropped drastically for no reason.. I have a 2.33ghz intel quad core with 4 gigs ram and 1gig vram nvidia 9500gt

That thread has more info than just microstuttering. Can you post a DxDiag log please?

here is my dxdiag

Have you upgraded your video drivers directly from the nVidia website? Also try getting a program called HWMonitor to watch your system temperatures. You also should try and play at a lower resolution and turn off shadows just to see if that helps fix the issue.

normally i play games at 1920x1080 but i play this at like 1280x720 or something but i always ran the game at all high low shadows and 1280x720 and it stayed at 60 fps at all time. I will go check out the HWmonitor because just in the past few hours my computer has shutoff twice instantly by itself so im thinking it might be heat related now

EDIT: Alright so heres the temps all 4 cores seem to be between 70-80c now i know a few days ago i was messing with a single core comp of my girlfriends and i got it down to about 40c with just a heatsink and fan.. idk if the quad cores will naturally run hotter or if that is indeed to hot. nvidia 9500gt is at 54-56c. I guess i will mess around with the heatsink some and see if i can get it down. But as i said i am not sure if quadcores just naturally will be hotter or if the heatsink just isnt doing its job.

Could be a fan died or something like that maybe, good luck I hope you this works for you.

Maximum running temperature for that processor is around 71 C, coupled with your computer restarting does seem to indicate a heat issue or hardware problem.
