didn't find this issue elsewhere, so I post it here.
Got the Limited Edition (german) and gameplay starts fine with 30 - 35 fps. After about 10 minutes, the game starts jerking and drops to 3-4 fps. This situation remains for about 20 seconds, then the system returns to 30 - 35 fps again. After that, every 3-5 minutes, the problem occurs again. I didn'check if MP behaves the same.
There is no HDD activity at this time, no game saving, no heavy duty process in the background, no temperature issue. I play a lot of 3D games (shooter, RPG, etc) and never experienced such behaviour before. The only game, that also had similar fps drops as Crysis 2 was Crysis Warhead.
Has anybody any hint for me?
System is Core2Duo @ 2,53 GHz, NVidia Geforce GTX260M (driver 266.58), Vista64, 6 GB Ram, HDD defragmented, background processes reduced to the nessessary (no toolbar i.e.), DirectX up to date.
Game running @ native 1440x900
Thank you for any help.
