So, here's my findings. Easy install, portable enough (having to specify a bunch of folders and manually creating them could be better) at first sight the interface is nice. And that's really where I stop, because it took... what, I think it was over 5 minutes to initialize the first render? All to error out (gracefully! Kudos for that) because it was out of memory. I couldn't find anything else to close, so basically on the M2 with 8gb it won't run. It was 512x512 SD 1 model. https://apps.apple.com/app/id6444050820 works on all sorts of Apple devices, is free, and kept very updated... I mention it because it's fast (14 seconds 512x512 20 steps V1 on M2), can do SDXL and refiner even with 8gb (once, I doubt many will do it a second time, but a couple of minutes for 1024x1024 20 is still "doable"). I'll stick with that on Apple stuff :)
I had hopes to try it on the Steam Deck but I saw no mention of AMD at all. Still! I'm probably going to try the tensorRT stuff on Windows, my 3060 should do it and I don't know how to do it with Automatic1111 XD
If it's just the net framework, installing proton tricks will be faster. Select the game, install software, net framework.
