Measuring Input Latency on Linux: X11 vs. Wayland, VRR, and DXVK

281 hoechst 2026-07-14 17:03:40 UTC marco-nett.de Qwen Share 156

Developed a hardware tool to measure Linux gaming latency, finding VRR and dxvk-low-latency reduce latency more than X11 vs Wayland differences. XWayland adds ~3ms latency, while optimizations like VRR and low-latency pacer improve performance by 0.2-0.5ms, with real gains in smoothing frame pacing.

The Tower Keeps Rising
