Are you sure that the DX12 performance loss is already addressed on Nvidia GPUs? Do you have a source?

They are the proprietary drivers from NVIDIA that should now “just work” across kernel upgrades (like AMD has forever).
Are you sure that is how it works for AMD in Linux?








I feel that “works” is a very broad term. It can work but doesn’t mean that it will perform even or better in a good amount of games compared to Nvidia on Windows or AMD in Linux or Windows. Issues depends on specific games that one plays, one may be playing games that aren’t prone for those issues reported.
