AMD is actively working on a trimmed-down version of FSR 4 for RDNA 3/3.5 iGPUs, but there is no confirmation of when it will be arriving. In the meantime, a YouTuber has discovered a method of injecting FSR 4 at the driver level that works with RDNA 3/3.5 iGPUs. Channel AncientGameplays published a video showing how to do this using a third-party tool known as RadeonTuner.
RadeonTuner is designed to serve as a lightweight alternative to AMD's Adrenalin software. The application is functionally very similar to Adrenalin, with support for GPU overclocking and fan tuning. The application also allows users to change driver-related graphics settings and display settings. The main feature AncientGameplays was most interested in is the app's built-in overrides for FSR upscaling, frame generation and ray regeneration.

With the FSR override disabled, Spider-Man 2 showed upscaling support for FSR 3.1.5, but turning on the override changed the FSR version in-game to FSR 4.1.1. Spider-Man 2 also showed an asterisk next to the FSR 4.1.1 name, confirming the FSR version was being injected from the GPU driver. The YouTuber also tested several games using this FSR override method using a Strix Halo APU with an RDNA 3.5 iGPU and found it worked almost flawlessly (some issues with shadows and reflections reportedly occur at aggressive upscaling settings).

Using RadeonTuner's built-in FSR override is likely the best method to run FSR 4 unofficially on RDNA 3/3.5 iGPUs currently. Other hacks exist that also enable FSR 4 compatibility with these iGPUs, but injecting FSR 4 at the driver level unlocks compatibility with games using strict anti-cheat programs. However, it is worth mentioning that RadeonTuner is not an official application from AMD, so use it at your own risk.
AMD introduced FSR 4 support to RDNA 3 desktop GPUs recently with the release of Adrenalin driver 26.6.2, marking AMD's first step in supporting older Radeon hardware with its machine-learning version of FSR. AMD was also able to make the RDNA 3 version without compromising image quality compared to the RDNA 4 version.
Frequently Asked Questions
Open a question for an answer from TweakTown's coverage of this news, or ask your own below.
Will using RadeonTuner's FSR override on an RDNA 3.5 iGPU allow frame generation and ray regeneration features in addition to FSR 4 upscaling?
Are there known game-specific visual issues (like shadows or reflections) when using RadeonTuner's FSR 4 injection at aggressive upscaling settings on RDNA 3/3.5 iGPUs?
Does RadeonTuner's driver-level FSR injection bypass compatibility problems with games that have strict anti-cheat systems compared to other unofficial hacks?
What risks or limitations should I expect when using RadeonTuner (a non-AMD app) to enable FSR 4 on RDNA 3/3.5 iGPUs instead of waiting for AMD's official trimmed-down FSR 4 release?

AMD is currently working on getting FSR 4 working on RDNA 3/3.5 iGPUs (as previously mentioned), the Steam Machine, and RDNA 2 GPUs (the latter of which will be arriving in 2027).
