My system contains 2x EVGA 680 GTX classifieds and 2x X5650 prozessors (24x3,6 GhZ) with 48GB ram (Win 7 x64). A friend of me got 2x 680 classis too and got an i7-2600 @ 4,9 GhZ - that makes no difference - he got this exreme laags too. Some friends play with one 6xx series card and got the same problem...
I hered about some AMD users they got the same problem. What the heck produces this massive laags? I think its a problem with the engine in combination with the multiplayer - drivers are optimized i think...
Will there come a patch crytek? Without it makes really no fun...
