Drop *THIS* in your slrr folder, press PrntScrn(printscreen) to take screenies, it is a bland setup, so if you want any effect you'll have to activate them by your own. I always use this instead of slrr's F12 because with this you get better antialiasing and quality overall, check the two pics below(reflections, grill, logos etc):
SLRR
FXAA
Mind what i said before, it's pure SLRR and gpu AA, not FXAA AA.
