NVIDIA has released its GeForce Game Ready Driver 621.24 WHQL, introducing optimizations for Warhammer 40,000: Dawn of War IV and preparing GeForce RTX systems for upcoming DLSS upgrades in Where Winds Meet and Assetto Corsa Rally. The driver is available through the NVIDIA app and the company’s official driver download service.
Announced on November 11, 2026, the update supports three PC games, including two scheduled to receive additional rendering features later this month. NVIDIA has also included fixes for issues affecting Chaos Vantage and video playback in Windows.
Warhammer 40,000: Dawn of War IV receives Game Ready optimizations ahead of its December 3 worldwide release. Developed by KING Art Games and published by Deep Silver, the real-time strategy game features Space Marines, Orks, Necrons and the Adeptus Mechanicus, alongside cooperative campaigns, skirmishes and multiplayer battles supporting up to three players per team.
Players purchasing the Commander Edition can begin playing on November 30, three days before the standard release. NVIDIA recommends installing driver 621.24 for GeForce RTX systems, including those using DLSS 4.5 Super Resolution to improve performance.
Where Winds Meet is also included in the release, with NVIDIA preparing for the game’s November 23 update introducing DLSS 5 with 3D-Guided Neural Rendering.
Developed by Everstone Studio, the open-world action RPG already supports DLSS Super Resolution and Multi Frame Generation. The upcoming addition will introduce NVIDIA’s newer neural rendering technology for GeForce RTX 50 Series and RTX Spark systems.
Unlike conventional upscaling, DLSS 5’s 3D-Guided Neural Rendering uses information from the game engine, including geometry, textures and lighting buffers, to enhance the appearance of lighting and materials while preserving the underlying scene structure.
The technology is part of NVIDIA’s broader November 2026 DLSS 5 rollout, which also includes Hogwarts Legacy and War Thunder.
Assetto Corsa Rally is the third major game supported by driver 621.24. The racing simulator, developed by Supernova Games Studios in technical partnership with Kunos Simulazioni, is scheduled to receive DLSS 4.5 and Dynamic Multi Frame Generation on November 19.
The game entered Early Access with DLSS 4 Multi Frame Generation, Frame Generation and Super Resolution. Its upcoming update will expand those capabilities with improved rendering and dynamic frame generation support.
Dynamic Multi Frame Generation adjusts generated-frame output based on performance requirements and supported display conditions rather than relying exclusively on a fixed frame-generation multiplier. NVIDIA says the update is intended to improve the experience on compatible GeForce RTX and RTX Spark systems.
The addition continues the adoption of DLSS 4.5 and Multi Frame Generation across PC games, although individual features depend on the installed GPU and each game’s implementation.
Beyond gaming optimizations, driver 621.24 addresses two application-related problems. The first fixes an issue in Chaos Vantage where the NVIDIA OptiX Denoiser could fail when processing scenes at high resolutions.
The second resolves incorrect color reproduction when playing DJI D-Log H.265 video files through Windows Photos and Media Player.
NVIDIA has not listed any gaming-specific bug fixes in the release notes for this version.
Importantly, installing GeForce 621.24 does not immediately activate the upcoming DLSS 5 and DLSS 4.5 additions in Where Winds Meet and Assetto Corsa Rally. Those enhancements require the respective game updates scheduled for November 23 and November 19.
GeForce users can download the WHQL-certified driver now through the NVIDIA app or NVIDIA’s official driver website. The driver supports a broader range of GeForce graphics cards, but the new DLSS capabilities remain subject to their individual hardware requirements.
