Can play game no problems on near max settings with a nice high(ish) framerate and no lag whatsoever but after 10 minutes my game becomes unplayable. It's practically locked up and my cpu is at 95-100% according to task manager. This happens with all cryengine games and only cryengine games. Happens with both crysis 2 and amazing spiderman. I cannot play either of these games because of this issue making these games I paid for unplayable.

Windows 64bit
4GB RAM (corsair XMS3)
Athlon X2 265 (clocked at default 3.3ghz)
HD6850 1GB

Amazing Spiderman is not a Cryengine game?!
