Linux Input Latency Benchmarks: X11 vs Wayland, VRR and DXVK Compared

The article examines how input latency varies across Linux display servers. It compares the traditional X11 system with the newer Wayland protocol. Measurements include scenarios with variable refresh rate (VRR) enabled. The study also evaluates the impact of DXVK, a DirectX‑to‑Vulkan translation layer. Tests are performed using a consistent hardware setup to isolate software effects. Results show distinct latency differences between X11 and Wayland under VRR. DXVK introduces additional latency overhead in certain configurations. The findings help developers choose the optimal stack for low‑latency Linux applications.
