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.

Each week, we bring you news of the latest DLSS and ray tracing integrations in games and apps. Last week, Remnant II launched with DLSS 2, new DLSS 3 integrations were revealed, and Ratchet & Clank: Rift Apart launched with NVIDIA DLSS 3, NVIDIA DLAA, NVIDIA Reflex, and NVIDIA RTX IO. August looks to be another great month for DLSS and RTX, headlined by the official launch of Baldur's Gate 3, enhanced with DLSS 2 and DLAA.

Additionally, DLSS 3 has been added to DESORDRE: A Puzzle Game Adventure and Remnant II, and will be available at the launch of Lost Soul Aside. And as for DLSS 2, Grand Emprise: Time Travel Survival has just launched with support for frame rate accelerating technology. For gamers with GeForce RTX GPUs, DLSS ensures you receive the definitive experience in each title, and thanks to GeForce RTX Ray Tracing Cores, you'll enjoy the highest possible frame rates when enabling ray-traced effects in DESORDRE: A Puzzle Game Adventure and Ratchet & Clank: Rift Apart.

Every week, we bring you news of the latest DLSS and ray tracing integrations in games and apps. Last week, we celebrated the launch of Portal: Prelude RTX, a path-traced remaster of a classic mod, made in NVIDIA RTX Remix and enhanced with full ray tracing, NVIDIA DLSS 3, NVIDIA Reflex, and our new, game-changing NVIDIA RTX IO GPU-accelerated storage technology. The good times keep rolling this week with the arrival of Ratchet & Clank: Rift Apart on PC on July 26th, featuring NVIDIA DLSS 3, NVIDIA DLAA, NVIDIA Reflex, ray tracing, and NVIDIA RTX IO, giving GeForce RTX gamers the definitive PC experience, with the fastest possible PC frame rates, the most responsive gameplay, and the highest levels of detail.

And DLSS is also coming to more of your favorite games. Today, the eagerly anticipated Remnant II launches with DLSS 2. Additionally, the action game SYNCED is launching this Summer with DLSS 3, and Wuthering Waves announced that it will launch with DLSS 3, too. Finally, the ever-popular DLSS 2-enhanced NARAKA: BLADEPOINT celebrates its second anniversary with a special event and by transitioning to a free-to-play model, enabling even more people to play.

Portal remains a timeless classic; in December we released Portal with RTX, a fully ray-traced reimagining of Valve's award winning game, which used the performance multiplication of NVIDIA DLSS 3 to power the most realistic path-traced lighting ever seen in a real-time game. Portal with RTX was created using NVIDIA RTX Remix, a free, upcoming modding platform built on NVIDIA Omniverse, which enables modders to quickly create and share #RTXON mods for classic games, each with enhanced materials, full ray tracing, NVIDIA DLSS 3, and NVIDIA Reflex.

Now, RTX Remix has been used to remaster Portal: Prelude, the highest rated Portal mod, the 2008 Portal ModDB winner, and #3 overall Player's Choice mod of 2008. Created by Nicolas "NykO18" Grevet and others, Portal: Prelude is an unofficial Portal prequel, set before the time of GLaDOS, featuring a new extremely challenging 8-10 hour campaign composed of 19 new test chambers, new advanced gameplay mechanics, a fully voiced story with NPCs, and a whole lot more. Portal: Prelude RTX is available today to download from Steam, for free!

Rapid loading and smooth navigation through endless open worlds has long been a goal of gamers and developers alike. Even with the incredible performance of NVMe SSDs, this goal has remained out of reach. Modern game engines have exceeded the capability of traditional storage APIs; a new generation of Input/Output (IO) architecture is needed.

Enter NVIDIA RTX IO, enabling fast GPU-based loading and game asset decompression, massively accelerating IO performance compared to hard drives and traditional storage APIs. NVIDIA RTX IO leverages GPU decompression for smaller data packages, enabling faster load times and lower CPU utilization, allowing developers to create a new generation of games with massive, highly detailed worlds. NVIDIA RTX IO makes its debut alongside the free Portal: Prelude RTX mod today, and will also feature in Ratchet & Clank: Rift Apart, launching July 26th.
