I've been testing the new framerate limiting modes on the RTSS Beta and the Scanline Sync x/2, and i can't reach a conclusion about which mode is best in terms of frametime smoothness. Scanline Sync /2 works really well, when the target game accepts it, you get no tearing and no extra inputlag (Normal VSYNC 30FPS input lag is horrible, makes everything unplayable), and the frametimes are smooth. frametime fluctuations are minimal, +-0.02 up or down on frametime graph. However if the framerate drops to something below the 30FPS mark on any given moment (like on a disk acess microstutter), the stutter is rather severe (like a frame of freezing). I don't personally mind the scanline hitching while on high GPU usage, i'm way more sensitive to (micro)stutters. While testing the new framerate limit modes, i've noticed some things on my 60hz TV: (All tests done using a controller and Vsync OFF) - Tearing is obviously present. - With async mode, no frametime graph fluctuation, even when (by eye) you can spot the difference, the graph remains untouched. - With front edge sync, the frametime graph fluctuates +-0.01ms, much like Scanline Sync fluctuations, however at an even lower margin. - With back edge sync, the frametime graph remains untouch much like in async mode, however (by eye) it looks a little more smooth than the async method. While you can get the best of both worlds with Scanline Sync, some games really hate it, like The Division 2, which has an infamous bug where you CPU can easily get to 100%, and every enemy encounter gives you some stutters, Scanline Sync makes the game's unplayable while in combat. So, for someone who doesn't mind the tearing, which method would be the most advisable for a 30FPS lock on a 60hz TV/Monitor? If using VSync off, is it a good idea to use the "true refresh rate" - 0.01(/2 for 30FPS) like the BlurBusters LowLag Vsync guide does, or is a 33.3ms lock sufficient?
