ive been having issues with stable framerates while playing battlefield 3 online. it will start out fine with fps between 60 to 100 but after a short time it will drop to between 10 to 30 and occasionally jump to 60 or 70 for a very short amount of time before dropping again. i played within a window to watch what was happening and it seemed to stay running at 2.7 to 2.8 ghz. temp was running from about 88 to 95 degrees Celsius
i am running all settings on low ingame and resolution of 1360 x 768 at 59hz. first of all, my machine. dell xps l521x - didnt specifically buy it for gaming but after breaking my hand it was my only option for gaming. specs looked good enough to run the games i wanted to play.
