NVIDIA today released the latest version of its GeForce Game Ready drivers. Version 551.86 WHQL comes with optimization for "Horizon: Forbidden West" Complete Edition, which includes support for DLSS 3 Frame Generation, and Reflex. The game also supports DLSS 2, and the DLAA preset that provides the best possible image quality. Next up, the drivers add optimization for the latest update of Portal with RTX; which adds support for DLSS 3.5 Ray Reconstruction, and RTX-IO (also implemented as DirectStorage). The drivers also add GeForce Experience optimal settings for "Helldivers 2" and "Three Kingdoms Zhao Yun." Lastly, NVIDIA expanded the list of G-SYNC compatible displays with 11 new monitor models.

Among the gaming bugs fixed with this release are a problem where Advanced Optimus-featured notebooks won't wake up in NVIDIA GPU-only display modes; and a stutter noticed in "Hitman 3" on some Advanced Optimus notebooks. A bug that caused RTX HDR saturation and tone-curve matching Gamma 2.0 instead of Gamma 2.2 has been fixed. Incorrect RTX Digital Vibrance detection for Paint.net as a supported app, has been fixed.
