Maximum Pre-Rendered Frames
Does this setting actually do anything for SLI? Or does it only affect single GPU setups? I've tested a bunch of games at length with MPRF set anywhere from 1 all the way to 8, and it seems to make absolutely [b][i][u]zero difference[/u][/i][/b] on performance or input lag in SLI. On a different single GPU system, lowering MPRF to 1 noticeably reduces input lag in many of those same games.

this setting controls the frames prepared by cpu before they reach the swap queue.

[quote="Sora"]this setting controls the frames prepared by cpu before they reach the swap queue.[/quote] I know what it's supposed to do. But I want to know whether it's functional for SLI, since testing all values between 1 to 8 inclusive had no effect whatsoever. It seems to only work in single GPU.

SLI uses driver side quad buffering and splits frame preparation across additional driver multithreading. It might not be prerenderered frames compatible.

That's what I figured.
