Cheeks Spread for Digital Only Future
Thing is you can do that with FSR to replace DLSS and sometimes vice versa if FSR is implemented as a .dll.FSR is always an option. It was used on Avatar in the first place and looked better then so devs should use their own eyes and implement what works best. If all someone did was do a CTRL + F to replace FSR with PSSR with no real testing then that's on them.
You should be able to just replace FSR with PSSR if you have access to the code.
