Well, only in that they do 2 fields per frame. :-) Apologies, BTW, guys; my last 2 replies were inadvertantly off list; feel free to reply them back on. > > Will also committed a mod in CVS to use hardware acceleration if > > available in full-screen mode - sounds like it would be worth giving > > that a go as well. > > It's enabled by default in CVS but it doesn't actually seem to help at > all (that I can detect).

I *may* get by with one X server; I may not. Optimally, I'd like to have 4 Xvnc servers and 4 real ones; if one gets locked up mid show, it's more likely to be a hardware server; that wasy i could restart it without breaking the show. I don't know that I'll be doing that on an laptop, of course. > pycdg.py plays along just fine by specifying the correct geometry and > position, too. I can routinely squeeze 50 FPS out of it at 800x600. If > I try for 60 FPS, it loses sync with the audio and isn't usable. Mine is much less happy than that, but, of course, that's at 1280x1024. Can "fullscreen" mode change the scan rate of the X server? Set it to 640x480x8, and the problem would likely evaporate. Cheers, -- jra -- Jay R.
