I just bought 5700XT and I like it very much, but ReLive can't record minecraft in fullscreen, which is very disappointing for me. ShadowPlay has recorded MC perfectly and ReLive can't do it. Do you plan to add support for recording OpenGL games in fullscreen?
I don't know if this will help with your GPU, but I was able to make Relive work in windowed fullscreen on my RX580. It's the same as fullscreen, but doesn't block the Windows key; able to interact with Relive outside the game. I also discovered VSR makes Relive "think" the OpenGL game is protected content, so I disabled it.
