I have SLI 680 2GB, i5-2500k at 4.2ghz, and 8GB of vram. I play at 1440p and have very bad framerates in Crysis 3.
I originally tried running settings of MAX, with AA OFF. This resulted in low 20s for fps in the first rainy open area where you fight some humans immediately after getting crossbow. If I exploded a barrel in this area, fps go into the teens.
Tall swaying grass areas are around 30-35 fps if a couple of small enemies are on screen. Maybe 35-40 if no enemies. Cutscenes are usually around 25fps, but sometimes also dip into teens.
I have tried tinkering with options. Keep in mind each of these tweeks was in conjunction with also having AA OFF each time.
Lowered Post Processing down to lowest setting ( around 2fps increas in some areas, none in others)
Turned Shadows down to lowest setting (no noticeable fps increase)
Turned AF down to x8. No increase.
Can anyone provide a decent combination of settings at 1440p that has an acceptable framerate? It seems like so far around 3 hours into campaign, and 30-35 fps seems to be about as good as it gets, unless it is a narrow corridor.
Do you think the 2gb effective vram is bottlenecking at 1440p with this game, even with AA completely off? I knew spending $1000 for 2GB would bite me in the ass one day, just didnt expect it to be within 10 months....
