Recently I bought an Rx 570 8GB , it seemed to work pretty much as expected, but on Minecraft it didn't seem to even recognize it I did everything every single fix to solve it but unfortunately I guess Nividia has recognized this issue and fixed it with their software panel, and AMD didn't. The thing is Minecraft is a CPU dependable game and it doesn't use the GPU I mean I am still having the same FPS or the same game quality as I had with my R7 Radeon GPU I hope someone get involved in this thing and help me and help all of the Minecraft users who are using AMD GPUs. I think it's a very easy thing AMD can add with their new software update as Nividia has already done it.
This tutorial shows how much its easy to switch from integrated to dedicated GPU memory on Nividia Cards.
I hope I can get a fast reply.
