hi,
yes and no, i’m on a mac m1, so it’s an all integrated chip but i’m not sure it"s relevant to compare to igpu (specially about memory bandwith)
from run pressed to loading message it s about 1~2 second of white screen then, 1s of “loading”
otherwise i don t see any bottleneck, next i will try to temporary replace textures with small images to check, i think it can be that textures are effectively uploaded to videocard only at first display
