Hi, I recently switched from Windows to Linux as my daily drive. I picked Fedora since it supports secure boot, and I can still boot into my Windows and play League of Legends (the only thing keeping me there). Other than that, it’s been a smooth ride. This is not my first attempt but this time I did something different that I hadn’t done those other times, I thought lets use my claude subscription to handle things for me and so I did and it’s been insane how fast it fixes all the potential problems and installs my drivers and finds the settings I want quickly for me, although it might sound bad I’ve asked it to track every decision and command it runs in my machine in a private repo that I ask it to keep updated everytime so I have some kind of changelog of my machine but over all very smooth experience. I thought, “Well, why not let it install my game, Red Dead, and optimize it for me?” That’s when I found out more about FSR and game scope; it searched for the recommended settings for my machine and gathered information from different community pages, and the result has been insane for me. I have a flashed RX 5700 -> RX 5700 XT. I could play Red Dead Redemption on it with decent quality at 1440p (sure it’s upscaled) and hit 190! FPS at times, it’s phenomenal. I’ve never seen my card hit these numbers, and to be honest, I’m happy with the quality of the game even though it’s upscaled and I have fake frames. It’s such a smooth experience, and my card has gotten a totally new life. I tried several other games and had the same experience everywhere. I thought I would make a video and record my gameplay and put it on YouTube so people can watch it and use the settings as well. If you have any questions, hit me up. https://www.youtube.com/watch?v=ivDFitbCoSY This is the reasoning on how this was possible (AI response): RDR2 does not support FSR 3.1. Out of the box it only has FSR 2 (added in a 2022 patch) and DLSS 2, and no frame generation at all. The secret sauce is a mod that fakes it. OptiScaler: the main trick
- It’s a small DLL dropped into the game folder (winmm.dll, with the Wine override winmm=n,b).
- When the game calls its built-in FSR 2, OptiScaler intercepts that and runs FSR 3.1.4 instead, which is a better upscaler.
- It then adds FSR 3.1 frame generation on top: it hooks the game’s frame output and inserts a generated frame between every two real ones. That roughly doubles the number on the counter.
- Frame generation only works in DirectX 12 mode, not Vulkan, so the game runs in DX12. Upscaling from a low internal resolution
- FSR 2 is set to Performance in the game, so it renders at only 1280x720, and FSR 3.1 rebuilds that to 2560x1440. That’s the biggest real-fps gain. Smart settings
- Ultra textures, which cost almost nothing on an 8 GB card.
- Shadows and lighting on Medium, the most expensive settings.
- Volumetrics and GI on High, motion blur off, VSync off. The Linux side
- GE-Proton 11-11 with vkd3d-proton turns DX12 into Vulkan.
- RADV_QUEUE_DISABLE=compute avoids the RX 5700’s GPU-hang bug.
- vulkan-1=b fixes OptiScaler crashing on Rockstar’s old bundled Vulkan file.
- gamescope runs at native 1440p with no extra scaling.
- GameMode keeps the CPU at full speed. submitted by /u/Impossible_Sir_3598
