Full release next year, Wine Fork + fex core and many good things, no bottleneck of any kind. Vulkan 1.1 minimum. Video coming from me next year of GTA IV running on Helio G80 with Mali G52.
Cassia Windows Emu is being developed by Mark and Bylaws, while Strato is the continuation of Skyline by Lynx and TheASV.
It’ll take more than just a compatibility layer for it to even come close to competing with the Steam Deck, or just Proton in general, IMHO.
