I am enjoying it more now. The gunplay is quite good I think.
Also, I managed to get it running at a constant 60fps with no slow downs or stutter (gpu usage is nice and low as well meaning low heat and no noise)
2x 670 sli - All ultra except textures and shadows, 1080p with FXAA. Looks good and runs silky smooth at a capped 60fps, never seen it drop yet since going from 4xMSAA to FXAA.
The only remaining issue is water reflections, for some reason as you move the camera the reflections appear and disappear as you look up and down the water. It looks stupid and I don't know what is causing it. I think it must be a bug. Does anyone else get this?
