War Thunder hotfix 2.55.1.165 fixes a ray tracing bug and an FPS cap issue

Gaijin posted War Thunder update 2.55.1.165 on June 17, 2026, with two graphics fixes at the center of the hotfix. It corrected ray reconstruction so the ray tracing setting actually turns the feature on, and it fixed a NVIDIA Reflex problem that could leave V-Sync active and cap FPS.

It follows the 2.55.1.92 update, which cleaned up chaff handling on three aircraft.

The note list is short, but both fixes matter for players who use ray tracing or NVIDIA Reflex to tune image quality and performance.

• Fixed an issue where enabling ray reconstruction in the ray tracing settings did not actually activate the feature.
