>Can you no longer alt-tab back into your regular OS?
I mean this in all sincerity: How old are you? Multitasking, such as alt tabbing, is something on machines since... Windows 95? Games before that, and games on 95/98 that launched in MSDOS, didn't have the ability to alt tab as the concept of things like "taskbar" weren't a thing. The games in question that did this stopped in the 1990s.
> Does it require high-tier hardware meaning you lock out all the poorfags on 10 year old laptops?
Actually it would lower requirements since the PC is not loading Windows, or another OS, itself. That's a lot of freed RAM.
