Integrated Radeon 890M performs AMD’s FSR 4.1.1 upscaling after Valve’s new Proton Experimental
A recent update to Proton, the Linux gaming compatibility layer developed by Valve, allowed AMD FSR 4.1.1 AI upscaling technology to be enabled on an integrated GPU. The feature, which is one of the highlights of the update, was seen operating on a Radeon 890M, which uses the RDNA 3.5 architecture. This feat is notable, as it comes after statements from AMD itself that generated uncertainty about official support for integrated graphics solutions.
The digital file that made this new feature possible, called “amdxcffx64.dll”, was made available by Valve in the Proton Experimental repository, anticipating the official launch of FSR. This version of the technology was adapted for older video cards, based on the RDNA 3 architecture, using a simplified data format, INT8, in contrast to the higher precision FP8 present in the Radeon RX 9000 with RDNA 4.
Immediately after publication, enthusiastic users downloaded the package and began testing it on various components. They confirmed that, in addition to the Radeon RX 7000 cards, already announced as the main beneficiaries of the update, even Intel Arc GPUs were able to use the new enhancement method.

However, the point that most surprised the community was the ability to enable the functionality on integrated graphics processors, especially on the Radeon 890M, which integrates the RDNA 3.5 architecture. The admiration arose because the AMD team had signaled that this type of GPU would not officially receive the feature. This possibility opens a new path for users of notebooks and compact systems, who could, in the future, enjoy significant improvements in gaming performance.
For the technology to work in this scenario, it is still necessary to use additional tools. Players needed to copy the amdxcffx64.dll file to the game folder, replace the amdfidelityfxupscalerdx12.dll file, and finally activate the FSR4Update parameter in the OptiScaler.ini configuration file. In-depth details about the performance achieved have not yet been widely released.
Even with the need for manual adjustments, the simple fact that FSR 4.1.1 can be activated and deliver the expected results demonstrates that the technology giant’s integrated graphics have the technical capacity to process the advanced upscaling artificial intelligence algorithm. This indicates that the ball is now in AMD’s court to work on adaptation and official availability.
It is likely that more information about the company’s next steps will be announced when the official launch of the feature takes place, which, considering Valve’s recent Proton update, should not take long to happen.
