That should not have surprised me since there are a lot of pixels to be moved around with 24 bits colour depth. That’s roughly 1 MByte of memory that needs to be addressed with a humble 8 bits CPU. Even when it would run at 50 MHz, optimized assembly code is required and tricks to get the optimal results. And even then it probably would disappoint. There is a reason why our old…
