AMD suggests using FSR with lower texture mip bias and I would love to see how it affects temporal stability (would be a very bad idea to do something like this in a game with MSAA for example), neighborhood clipping in TAA is good at cutting off high frequency signal, but any texture noise that survive should be quite apparent and can be futher exaggerated by RCAS.
Marvels Avengers shows the same temporal instability like Terminator: Imgsli
It is really bad.
Game doesnt support a simple resolution scale. But even driver upsampling from 1080p -> 2160p with nVidia doesnt introduce the negative lod artefacts: https://imgsli.com/NjE1Nzc
