Apple's mobile processors (especially the M1) are waaay faster than a steam deck. Even with the optimizations, it would take like half an hour to run I bet.
I dont think the Steam Deck is powerful enough. It might be possible but it will take hours.
cant you just run it the regular way? it's a pc.
It doesn't have enough VRAM to load the regular model; it ends up triggering the OOM killer.
