Are you able to mess with the first layer offset on the bambu printers? May need to bring your nozzle a bit closer, especially with a textured surface. Temps seem comparable to the stuff I have on hand.
For cleaning, is soap and water compatible with your surface? Personally found that while IPA is fine for maintenance, a few drops of unscented dish soap in water works extremely well as a degreaser, I’ve literally washed stubborn surfaces in the sink. Petg is super picky with any residual oils and the small nozzle could totally make that worse.
Maybe try running slower? Just to eliminate variables, may be worth running a quick extrusion calibration? Petg can be an absolute pain for bed adhesion in my experience.
I did it for the hell of it, I think it had 60-80 fpm after the opening cutscene, literal slideshow experience.
There’s people on proton db claiming higher frames, but like 18-22 fps, def far from playable
