Got my QBASIC demopart ready for testing, completely optimized and ready to roll. Found 486 owner (33MHz, 8MB of RAM) who tested it for me.

Takes 13 seconds for the scroller to draw each frame at 300x200.

No possible optimizations are present, everything's crushed as far as it'll go, meaning a completely different method of scrolling is needed.

(Still faster than the array method by 37 seconds per frame, but y'know...)

fuck me...
