try a different game thats graphically intensive, download the call of duty 2 demo and put the resolution at 1600x1200 and turn everything on to max if that works fine and u get decent frame rates then its your drivers that are causing the problems
1600res? a x1900xtx can do that? you sure? with 4 aa and high af? It can probably run i would have to play with it or try it i do have the game but only play at 1200 res and 4 aa all high maxed
what frames does it get? cod 2 as a lot of ai running around
