@cmuratori I have a question that unfortunately was too late for handmade hero today: In windows, window movement has 0 latency compared to the hardware mouse cursor. It follows pixel perfect. How does it do that? My own imgui has visible latency with vsync off and 0.2 ms frames.

ok, so I made a minimal example (118 LOC) where the backbuffer gets cleared to a different color on mouse move and the clear still only happens on the 3rd frame of movement. So 2 frames of latency. Would you mind taking a look at it and check if this also happens on your machine?

I uploaded the source and the exe to my google drive (needs d3d11): https://drive.google.com/open?id=1RmWEOtvZ8xGZNzBD_8GXi5b06eG_Q6u9 … for screen capturing I used obs, and when watching a video in vlc you can single step the frames by pressing "e".
