So if your monitor refresh frequency is 120Hz (cycles per second) and your simulator output frequency is around 150fps (frames per second), then your output will be limited to 120fps. You will notice a big difference if this is the case. With Vsync off, your framerate is no longer capped and is free to go as high as your GPU can handle, with no increase in input lag. on a 60Hz monitor, the maximum possible framerate with VSync on is 60 FPS. In other words - the difference in ms between 60fps and 144fps IS MORE than the one between v-sync on and v-sync off. Also, low-refresh rates enforce a high scanout latency ( high speed videos of refresh cycles ). 5y. Vsync and frame timing checked on in moonlight settings. 39. Set it to 138 at 142 in some titles it will go outside the range. VSync only helps with screen tearing, and it only really does that by limiting fps when necessary.
