Individual tinkers FSR 4 integration onto RX 7000 GPUs without AMD endorsement, yielding superior image quality yet slightly reduced frames per second compared to FSR 3.1.
Running FSR 4, AMD's latest upscaling tech, on an unsupported Sapphire Radeon RX 7900 XTX is possible, thanks to a nifty Linux setup. Here's how to do it using the latest Mesa update and the OptiScaler DLL injection tool:
Preparations:- Get the newest Mesa graphics stack on your Linux OS, allowing FP8 precision emulation for the RX 7900 XTX like FSR 4 requires via FP16 fallback.- Grab the OptiScaler DLL injection tool, forcing games to support FSR 4 even without direct support.- Use an updated Proton (or similar Steam compatibility layer) with FSR 4 compatibility.
Steps to Follow:
- Update your Mesa Driver:Give your system the latest Mesa graphics stack that incorporates FP8 precision emulation for AMD GPUs like the RX 7900 XTX. This allows the necessary GPU features needed by FSR 4 to be emulated on unsupported hardware[2][4].
- Obtain OptiScaler:Grab the OptiScaler DLL injection tool (the latest beta version can be found on GitHub or Discord communities). Extract the files from the provided zip archive[1].
- Inject OptiScaler into Your Game:
- Locate the game’s main executable folder (the folder with the .exe file).
- Copy all extracted OptiScaler files into this folder.
- Run the OptiScaler setup batch file (on Windows) or use an equivalent method on Linux. For Linux, this might involve setting environment variables or using Proton’s DLL injection capabilities to load OptiScaler.
- Choose the appropriate injection method, typically something like the "dxgil.dll" mode explained for Windows, adapted for Linux environment. This forces the game to enable FSR 4[1][3][4].
- Configure Proton:Utilize a Proton version patched for FSR 4 support (such as proton-ge with FSR 4 updates) to ensure proper injection with Linux games on Steam/Proton[4].
- Run and Test:Launch the game using Proton with OptiScaler running the FSR 4 functionality. Since FP8 is emulated, expect a performance hit compared to native support on RX 9000 series GPUs, yet image quality and upscaling should work fine on the RX 7900 XTX[2][5].
Summary:
| Step | Description ||------------------|-------------------------------------------------------|| Update Mesa | Get latest Mesa with FP8 emulation (FP16 fallback) || Download OptiScaler | Obtain DLL injection tool and extract files || Inject DLL | Place files in game folder, inject DLL via Proton or env. || Use Proton with FSR4 | Use a Proton version supporting FSR 4 || Run game and test | Launch game, verify FSR 4 upscale works on RX 7900 XTX |
This method is tested with success for games like Cyberpunk 2077 on Linux, enabling FSR 4 despite the GPU not officially supporting it yet[2][5]. Remember, there'll be some performance loss compared to native RX 9000 series GPUs, but image quality and upscaling will work just fine on the RX 7900 XTX.

- The nifty Linux setup to run the latest technology, FSR 4, on an unsupported smartphone or gadget could potentially be possible with a similar approach, as demonstrated with the RX 7900 XTX.
- Incorporating advanced data-and-cloud-computing techniques with artificial intelligence (AI), the OptiScaler DLL injection tool may be utilized to upgrade the graphics capabilities of unsupported devices, offering a better gaming experience.
- With AI-powered cybersecurity measures in place to safeguard sensitive information stored on smartphones, it is advisable to ensure that all gadgets and devices equipped with FSR 4 are kept up-to-date with technology advancements, such as opting for the latest Mesa updates and Proton versions.
