Yeah but a 1080p let alone 1440p is 4.3 times more data per frame, and at 
1440p 7.7 times more so double framerate doesn't make up for it. But just 
to be sure I recorded Hatari itself and made 1080p video from it at full 
50 Hz rate. The video player throws it around like it's nothing.


But Thomas had some nice ideas that might help (consolidating the 
SDL_UpdateRects into one call). I'm looking forward to the day it might 
becaome real :)
