So I was experimenting with PresentMon and different modes in Direct3D 11, using a basic game loop (SharpDX.Desktop.Windows.RenderLoop) and just rendering a rectangle at the cursor's location so I can get a good feel for latency just by moving the mouse. This is what PresentMon says and it definitely feels like it:
Fullscreen SyncInterval PresentFlags SwapEffect Latency #frames Tearing true 0 None Discard 0 yes true 1 None Discard 2 no false 0 None Discard 1 no false 1 None Discard 3 no
I have many questions, sorry:
The only way I can get less than 2 frames of latency is by uncapping the framerate, is that something I could address by using other settings? Maybe a waitable swap chain? Ideally I'd want to have windowed + capped framerate + 1 frame of latency.
Why does going from 0 to 1 SyncInterval add 2 frames of latency in fullscreen? I can understand 1, but why 2?
Changing MaximumFrameLatency doesn't affect these numbers in any way, I suppose this is because my game loop does practically nothing but I don't really understand how the mechanics work?
