Nowadays, who is responsible for a game to run, given there is a standard (DX12): the GPU manufacturers and their respective drivers which adhere to the standard or the "well-known" gaming studio who has a history of "complete and working" releases?
I own an A770 BiFrost Acer and actually in newer games it performs really great at 1080p/1440p/4k, even with RayTracing enabled. Also with DXVK I get insane results in older DirectX version games. What does it bring on the table? An affordable 16GB VRAM GPU, even best for buck I would say, 16GB...
I own this interesting chimera piece of hardware, and all I can say is that I'm pleased with the performance / power consumption / cooling solution.
In my opinion, this is a better pick on a long term than 3060 (used to own one before the Intel) and 3070 due to higher bandwidth, VRAM and...
Maybe it's time for AMD to dust off the HBM R9 Fury / HBM2 Vega64 development paths and reconsider HBM3 as a good source of more VRAM and end the planned clown-obsolesce of memory bottle-necked graphic cards. Also Nvidia shall take notes.
