@speednugget i tried it with and without msi afterburner, but got the same result. after alot of testing, i have found that running on the Drivers 266.66 is exactly the same as before. after about half a game of battlefield, it will start to lag every 10-15 seconds for a short spike. it's not as bad as the video portrays, but it's still relatively unplayable. i don't think the dx11 is a problem, as css runs in dx9, but i will try running bc2 in dx9/10. as for the processor, it does get pretty hot under load. after about 10 minutes in BC2, the program i was using (CPUID HWmonitor) said that the heat got to 65 C at the highest. it may get even hotter over time, but thats the hottest it was when the lag spikes started. i have not tried running on a diff OS/HDD, but i do have two hard drives, so that is possible. however, it is time consuming, and if that is not a valid cause then i would rather not. as for the CPU temp, is there any way to cool it off without buying a new heatsink/fan? i have a decent one on there, but the thing is almost touching my RAM and a different fan may not be an option (unless i use water cooling, but i'm a noob to this and not sure how it works, and i'm also out of money >.<) is there any sofware or an option in the BIOS that will let me choose fan speeds/ other ways to reduce the heat? and would an overheating CPU cause these problems? thanks ahead of time for any help or responses.
EDIT running BC2 in a lower DXversion did nothing.
