Unveiling the expansion of AMD's FSR 4 upscaling feature to an array of additional video games
In an exciting development for gamers using AMD's Radeon RX 9000 series GPUs, OptiScaler, an open-source utility, allows the use of AMD's FidelityFX Super Resolution 4 (FSR 4) in a wide variety of DirectX 11 and 12 games.
FSR 4, exclusive to AMD's RDNA 4 architecture, offers advanced AI-powered upscaling and frame generation. However, until now, it was only supported on games specifically designed for this technology. With OptiScaler, this barrier has been broken.
OptiScaler works by intercepting a game's existing upscaler calls and substituting AMD’s FSR 4 implementation at runtime. This is achieved by injecting a DLL into the game process and hooking the upscaling API calls, then forwarding the captured frame buffers and motion/feedback inputs to the chosen upscaler backend (FSR 4 in this case).
To use OptiScaler, gamers first need to download the latest release from its official GitHub page. Once installed, users can copy special FSR 4 library files into a game's installation folder. Next, they select FSR 3x from the drop-down menu and hit the 'Change Upscaler' button.
It's important to note that each game requires individual setup with OptiScaler as there is no universal installer. Also, OptiScaler may not work with multiplayer or online games that use strict anti-cheat protections like Easy Anti-Cheat (EAC) or BattlEye.
Performance and visual improvements may vary from game to game, depending on engine compatibility, asset quality, and how the original upscaling implementation was handled. However, the use of OptiScaler involves little risk as long as you stick to single-player titles and back up your game folders.
For more detailed information, users can find more resources on the OptiScaler GitHub Wiki page. This includes guidance on how to configure OptiScaler to use FSR 4 as the upscaler, and troubleshooting tips for common issues.
In summary, OptiScaler extends FSR 4's availability to potentially hundreds of DirectX 11 and 12 games, offering AMD Radeon RX 9000 series users a significant performance boost and improved visual quality in their gaming experience.
Smartphones and gadgets enthusiasts may find the news of OptiScaler intriguing, as it allows AMD's FidelityFX Super Resolution 4 to be used on a wider range of DirectX 11 and 12 games, not just those specifically designed for this technology.
With the aid of OptiScaler, AMD Radeon RX 9000 series users can enjoy advanced AI-powered upscaling and frame generation from more games, enhancing their gaming experience.
