Ah, now I see I made a mistake. First pic is from separate process renderer, and second is from normal render. First pic has s in it's name, second has n.

Yes, OS is 64bit. I just tried it with P7, same behavior. It would make sense that 64bit render has different output, but it's actually less in quality then integrated 32bit renderer. Shadows and motion blur is more grainy with FFRender.exe, they're more smooth with normal renderer.
