I have been playing stalker for some time and now it seems that after playing for some time my frame rate will start to drop to very low. This is not acceptable because I am running a GTX 780. In my first few hours of the game I was getting at most 110 FPS all the time. Now It will start at that and then decline to about 40-20. I am also running the stalker complete mod and I think this may have something to do with it. The frame rate seems particularly lower during the daytime but it is still well beyond 60 FPS upon restarting the game. I feel like my GTX 780 should be able to dominate this game even with the most GPU intensive mods. Anyone else have similar problems? Also it's worth noting that I recently updated to the new 335.23 driver and I did not have any of these Issues before updating.
