Will Xbox gamepass work with it? And how about games with kernel level anticheat tools?
Kernel level anti cheat is very likely never going to be resolved other than the company provider directly porting over their anti-cheat software.
I suspect this Winboat solution will be much more useful for application users: CAD, photoshop, quickbooks, other corporate software commercial or proprietary.
That likely gets us to 95% of what is needed to get off of Windows.
