Nvidia’s new driver prepares RTX PCs for Dawn of War IV and Where Winds Meet’s DLSS 5 update
Nvidia’s latest Game Ready driver prepares GeForce RTX and RTX Spark systems for Warhammer 40,000: Dawn of War IV and upcoming graphics updates for Where Winds Meet and Assetto Corsa Rally. Version 621.24 also lists fixes for video colour and a rendering application.
The driver is available now, but the game updates do not all arrive with it. Nvidia says Where Winds Meet gets DLSS 5 on November 23, while Assetto Corsa Rally’s DLSS 4.5 upgrade is scheduled for November 19.
Dawn of War IV launches on December 3; players with the Commander Edition can start three days early, according to Nvidia’s announcement. The driver is intended to prepare supported systems ahead of that release.

What changes for the three games
Nvidia says the new driver includes optimisations for Dawn of War IV, KING Art and Deep Silver’s real-time strategy game. It also supports the game’s DLSS 4.5 Super Resolution feature. The driver announcement does not provide a before-and-after performance figure for players to expect.

Where Winds Meet already supports DLSS features including Super Resolution and Multi Frame Generation. Its planned November 23 update adds DLSS 5 with 3D-Guided Neural Rendering for GeForce RTX 50-series and RTX Spark systems, Nvidia says. Installing the driver alone will not bring that later game update forward.
Assetto Corsa Rally is due to receive DLSS 4.5 and Dynamic Multi Frame Generation on November 19. Nvidia says the rally game already offered earlier DLSS Super Resolution and frame-generation options.

The driver fixes two non-game issues
The GeForce release notes list a fix for incorrect colours when Windows Photos or Media Player plays DJI D-Log H.265 video. They also list a fix for Nvidia’s OptiX Denoiser potentially failing at high resolutions in Chaos Vantage.
Nvidia lists no specific fixed gaming bugs in that GeForce section. Its RTX Spark driver has separate release notes, so owners of Spark-based PCs should check the relevant package instead of assuming every entry applies to both versions.
The GeForce notes cover Windows 10 and Windows 11 and include a supported-products table. Nvidia offers the driver through the Nvidia app and its website; check the listed GPU and operating-system support before downloading.
For players waiting for the three game changes, the useful distinction is between driver readiness and game availability. The driver can be installed now, but each developer’s game or feature update still has its own schedule.
