Yes but it’s so easy to run most Windows workloads on a VM that most people would just do that instead of doing the work to implement the needed APIs in Wine (ReactOS). I’m capable of doing such work. I can’t be bothered since everything I need runs alright in KVM. Valve takes care of games via their work on Proton (Wine). We often do this in the Linux world - reach for imperfect, easier solutions, then stack em on top of each other to form not that pretty yet stable Jenga towers. 😂
Yes but most machines these days have a ton of RAM and 4-8 CPUs. GPU is only required for 3D accelerated work. I think the standard QXL virtual GPU works fine for non-accelerated purposes. No idea how often licensing could be a problem. Haven’t had issues myself but I don’t use much proprietary stuff. Your standard MS Office, Adobe, AutoCAD stuff works fine to me.
