AMD FidelityFX Super Resolution (FSR) is an open source, high-quality solution for producing high resolution frames from lower resolution inputs. It uses a collection of cutting-edge algorithms with a particular emphasis on creating high-quality edges, giving large performance improvements compared to rendering at native resolution directly. FSR enables “practical performance” for costly render operations, such as hardware ray tracing.
While this patch file targets URP 10.6.0 in particular, you can still use this patch for other versions (including newer) with a few careful changes.
Use git apply <path to patch> when it's possible, from the correct place in your Unity project.
Use a normal editor to open this patch file. Look through all the diffs, and merge it into your local URP code manually.
After toggling on the Camera post-processing, the option for AMD FSR 1.0 will appear below it. You can choose different FSR modes according to your requirements.
At present, if you turn on FSR, the anti-aliasing (MSAA) setting will be set to 8X by default. You can change this to a lower MSAA level or other anti-aliasing solution. However, keep in mind that FSR 1.0 requires an anti-aliasing process before it can work. This is the MSAA setting: settings.msaaSampleCount = 8;
Mobile platforms (including those in standalone VR headsets) are not guaranteed to work due to the current compute shader implementation.
