Hello everyone. For a past few weeks I have been experiencing noticeably low framerates in all games. It's really annoying because right now I can’t play even deus ex human revolution which was very friendly to my setup before. My machine may not be the newest one but its not the worst on the market. My pc contains- Q6600 at 3.13 ghz, 2x2gb corsair ddr2 ram ~870mhz, hd5850 920/1200mhz, gigabyte ga-g31m-s2l (don’t laugh at it, I know it pretty much suc*s), ocz stealthxstream 600w and seagate 640gb hard disk (7200rpm). I use mostly 1280:1024 res (vista home basic 64b service pack 2). Framerate in deus ex human revolution reaches 30fps max (in town) and up to 50fps (in closed areas). In battlefield 3 open beta maximum framerate was around 20-30 fps all the times. well I know that this pc has it's golden era somewhere in the past but it’s not supposed to suck so badly atm especially that right after dx:hr was released I was actually able to run it maxed with 90-100fps. I noticed lower framerates in all my other games too, WoW, Crysis 2, the witcher 2... I would be very grateful for helping me out on this issue since its starting to wash gaming away from my life pretty much. What should I do?
