That sounds good but I’ll believe it when I see it. There aren’t many desktop container/sandbox implementations out there and most are “vm light” e.g the windows sandbox and sandboxie. I haven’t seen anything more lightweight that can run desktop apps (in Windows at least).
Not sure if that changed since its inception but originally windows store was exactly this: no SLI/Crossfire, v-sync always on, no overlays. Basically it was isolated from using the driver properly.
