AMD announced that the first games making use of FSR 3 are now available for this image upscaling tech. Unlike Intel XeSS and NVIDIA DLSS, AMD FSR is fully open-source albeit the initial code drop of FSR 3 is coming later.
A post around the technical details of FidelityFX Super Resolution 3 on GPUOpen.com notes that FSR 3 will still be MIT licensed and the code is coming soon:
"AMD FidelityFX Super Resolution 3.0, as with previous AMD FSR releases, will be made available soon on GPUOpen with a permissive open source MIT license. If you are interested in evaluating AMD FSR 3 for your game title, please contact your AMD representative to request early access."
At least under Windows the FidelityFX Super Resolution 3 tech is looking very promising and will be fun to see how well it ends up doing on Linux particularly in the Steam Play driven Linux gaming world.
