so i just tried smth and i seem to achieve 75 hz @ 1440x900 with my 22" 1680x1050 TFT

what do I have to look out for, except:
r_displayrefresh 75
r_mode 18


tft osd shows 75 hz and it's way smoother now
i hope i get accustumed to the shitty non-native resolution...


no vsync
maxpackets still @ 125


is everything fine now, or do i have to config work or hardware/driver things to or????
