I said what I said because it’s relevant today. I literally had this issue last month with modern hardware, when I couldn’t get HDR working properly in KDE 6 Plasma (colors are washed-out and have no contrast when HDR is on). And features from my GPU are completely missing, like SDR-to-HDR conversion, AI upscaling, and the entire 3D Settings Page (the one where you can change settings not available in-game). When I ask people for help with restoring these features/settings, no one has any idea what I’m talking about. So I gave up and went back to Windows.
Which is funny because the Neo-Geo was a very much sprite-based 2D machine. What did they even mean by “4D”?
