Here's how gamers can harness the power of AMD's FSR 4 technology with any title out there, given that it supports DLSS or XeSS upscaler, credits to the modding community.
OptiScaler, An Open-Source Tool, Now Allows You To Run AMD's FSR 4 On Any Title, But They Must Support DLSS/XeSS Upscalers
The debut of Team Red's FSR 4 technology made us hyped up about the future of upscaling tech, given that we saw massive performance uplifts compared to the older FSR 3.1 implementation. However, given that AMD made FSR 4 exclusive to the Radeon RX 9070 series GPUs, and the early-on support for titles was pretty confined, it did disappoint gamers out there. But, modders have decided to step onto the scene, now unveiling OptiScaler, a tool that allows you to run FSR 4 on any title, provided that they support DLSS 2+ or Intel's XeSS.
This tool has managed to break the boundaries between upscaling technologies and their exclusivity with gaming titles. For a quick explanation of how OptiScaler works, it acts as a "middleware" between upscaling technologies and gaming titles, rerouting upscaling requests to another supported technology. This is done through the implementation of API methods, and OptiScaler basically mimics the functionalities of DLSS, XeSS, and FSR so that the game believes it is still using the original method, which is pretty interesting.
The main question behind OptiScaler is the type of performance this tool brings onboard, and fortunately, the user @highyieldYT shared the usage of OptiScaler with Cyberpunk 2077, effectively bringing FSR 4 to the title. The individual recorded over 60 FPS at 1440p settings with FSR 4 enabled and the Radeon RX 9070 XT. Do keep in mind that Cyberpunk 2077 doesn't support FSR 4 or even FSR 3.1, so it is safe to say that OptiScaler has done its job pretty well.

Currently, the developer has listed a total of 22 titles that work with the FSR 4 compatibility mod:
- Atomic Heart (tested on DLSS Input)
- Avowed (tested on DLSS input)
- Baldur's Gate 3 (tested on DLSS input, need to use DX11 .exe. Arguably not worth due to lower performance than Vulkan w/o upscaler during tests)
- Black Myth: Wukong
- Control
- Cyberpunk 2077 (Need to use FSR or XeSS inputs, Crashes on Windows 10)
- Deep Rock Galactic (tested on DLSS Input)
- Dragon's Dogma II (set FGType=nofg)
- Final Fantasy VII Rebirth (tested on DLSS Input)
- Ghost of Tsushima (tested on FSR3 input)
- Hitman: World of Assassination (Use DLSS or XeSS)
- Horizon Zero Dawn Remastered
- Jusant (DLSS inputs)
- Kingdom Come: Deliverance II
- Lies of P (tested on DLSS input)
- Red Dead Redemption 2 (use DX12)
- Senua's Saga: Hellblade 2 (tested on DLSS input)
- Silent Hill 2 Remake (tested on DLSS inputs)
- Shadow of the Tomb Raider (tested on DLSS inputs)
- Tokyo Xtreme Racer (tested on DLSS inputs)
- Uncharted: Legacy of Thieves Collection (tested on DLSS inputs)
- The Witcher 3 Next Gen (tested on XeSS inputs)
It is indeed interesting to see industry boundaries being broken by open-source tools. Given that OptiScaler has managed to make upscaling tech cross-platform, we are excited to see how it evolves into the future.
