My application renders frames from a camera to multiple physical monitors. The application is highly sensitive to latency which needs to be as low as possible.
It is currently running on Ubuntu 20.04 but can be upgraded if required. I am using the Nvidia RTX card. Under X I open a full screen window for each physical monitor placing each window on its own x-screen. This allows me to bypass the compositor whilst maintaining v-sync and achieve low latency on all windows / monitors. 1. Is it possible under Wayland to bypass the composition and render directly to screen for multiple monitors/windows? 2. Is it possible to sync (v-sync) each window to a different physical monitor (This is only possible under X when each monitor is on its own x-screen)? 3. How much latency is expected to be added by the Wayland compositor when rendering a new full frame at 60fps)? Thanks, Shachar
