Question
why is PSD optimized with buttocks ?
How is it possible that such expensive software crashes as soon as an image exceeds 8k pixels? It's impossible to work comfortably.
FREE software like Unreal Engine manages hundreds of 8k images applied to hundreds of 3D models (with thousands of polygons), all lit in real time.
You should think about optimizing PSD other than by putting your big buttocks on the keyboard. What crappy software...
