Mali GPUs right now at least, dosent support Feature Level 12, not sure if is a driver thing or a missing hardware feature, so Windows gaming on Mali should work around the same as Kepler does with DX12 games as issues are concerned.
Most of the issues with these gpu are due to not target Windows as a platform. Something i dont understand, Windows 10 can run on Raspberry Pi 4 whiout a working GPU driver… it would be a totally valid platform if the driver stack. were OK.
