Help with Portal 2 with RTX support

[KingVulpes]

Hi, I'm the director of the upcoming Portal 2 with RTX Remaster from NightSightProductions and I'm reaching out because we want to implement FSR 3.1 to give AMD users a better upscaling choice but we have no idea how to implement the technology and devs who have tried before have had issues. We were hoping you guys could help us out with that to ensure RDNA 2 and above users get the best experience. Hope to hear back from you soon as NVIDIA is getting ready to announce this project soon.
