Signal. SimpleX is a second to that.

For that Theres VKD3D :P

Also, I specifically said legacy DirectX because the support DX11 and DX12 natively.

I only took FSR3 for reference because it’ll support one of the things you outlined xP

Because translating a game in real-time doesn’t negate the fact that it’s a windows game. As such, wine will report as being Windows 10 by default.

DLSS is a matter of Nvidia’s sub-par driver support. FSR2 (and soon FSR3, which does frame gen.) works, ironically even on Nvidia GPUs :P

Nobara and Pop!_OS do well in this regard.

It won’t just not render something. DXVK is already a finished thing in that regard. Complete enough that Intel uses it for legacy DirectX support in their ARC GPUs even.

That’s because the desktop client is basically brand new and in early development. (A GUI one, that is)
