Ever wonder about how the Sun Occlusion and HDR looks in game?
Here's my graphical matrix.
So images on the left are with HDR off, on the right HDR on.
Personally, I really couldn't tell if there was any effect (visually) of occlusion. But occlusion really does has effect on FPS. With occlusion on, I will lose ~3 FPS.
HDR visually more pronounced, as it should be. But since build 60 the effect is much softer now. HDR also eats the FPS. With HDR on, I will lose ~3 FPS.
So if I'm using both HDR and Occlusion, I will lose ~6 FPS in total.
