Compressing was indeed Imgur's fault due to me using BMPs as that's how SweetFX dumps screenshots, was too lazy to convert to PNGs beforehand. As for AA Fix I did try it and it doesn't make a difference. I also tried both of your flags but C4 is just as blurry, C5 however seems to be quite good. Thanks a lot. Edit. But yes, it does cause microstuttering with V-Sync ON. Guess I will stick to 0x000012C1 with OGSSAA + SMAA. This is 8xSQ (2x2 + 2x MSAA) combined with SMAA using 0x000012C1 flag.
