NVIDIA GeForce Game Ready 621.24 Driver Download: Warhammer 40,000: Dawn of War IV and Assetto Corsa Rally Support

Game Support and Rendering Improvements

Driver 621.24 introduces official Game Ready support for “Warhammer 40,000: Dawn of War IV” and “Assetto Corsa Rally.” For the latter, the update implements DLSS 4.5 MFG to improve image generation and overall smoothness. A significant technical innovation in this version is support for “Where Winds Meet.” The driver enables DLSS 5 for this title and specifically integrates 3D guidance data for neural rendering to improve image reconstruction and level of detail.

Bug Fixes

In addition to game optimizations, the WHQL package addresses specific software regressions and rendering errors:

Chaos Vantage

NVIDIA has fixed a bug related to the NVIDIA OptiX Denoiser. Previously, the denoiser could fail at high resolutions—an issue logged under reference number 6953474.

Playback with Windows Media

The update resolves a color accuracy issue affecting DJI D-Log H.265 video files. Previously, playing these files through the Windows Photos app and Windows Media Player resulted in incorrect color reproduction (reference number 6996250).

Currently, NVIDIA reports no known issues related to version 621.24. The update is available for download and installation via the NVIDIA download and installation page.
