Measuring input latency on Linux: X11 vs Wayland, VRR, and DXVK
Summary
The article documents a hands-on Linux input-latency measurement setup comparing X11 and Wayland, with and without VRR, and using a low-latency DXVK fork. It concludes that XWayland adds notable latency, VRR reduces latency across all configurations, and dxvk-low-latency provides a small but consistent improvement, especially in uncapped scenarios.
