So it should be possible to use the FX-card on an RGB with acceleration on
using VI! Great news. BTW. VI is great too. :-))

Okey, but I guess that you didn't use the "turbo-mode" 320x100 then?
If you use the latest version, 1.9, run it in RGB mode and press '3'
(or was it another key?), this will change the video mode to 320x100
insteed of 320x200 and it should increase the speed remarkably still
having the same screen area. :-)

Try it and tell us what you get. :-)
It would also be interested in testing this on the FX-card using VI
to be able to use acceleration using RGB/TV. :-)
