okay here we go.. (tech specs see my signature)
REV 16050 & ATI Catalyst
8.11 on xp
- fullscreen on tv (2nd monitor) is not possible.
- lots of tearing on tv in maximized window mode
- no tearing at all when playing video fullscreen on pc monitor.
REV 16050 & omega driver on xp
- no fullscreen on tv possible.
- lots of tearing on tv regardless of any settings made
- also tearing on pc fullscreen
REV 16051 & omega driver on xp
- fullscreen on tv possible, but reduces pc screen to same resolution. switching with \ ends up rendering the xbmc window useless on tv.
- lots of tearing on any windowed/fullscreen mode on both displays regardless of vsync and driver settings.
REV 16051 & ATI Catalyst
8.12 (!!) on xp
- fullscreen on tv possible. with settings "let driver choose" and vsync always activated on ccc there is
no more tearing!
and - TATAAAH..
REV 16604 & ATI Catalyst 8.12
with "let driver choose" and vsync in cc set to "always on"
no tearing at all. neither fullscreen nor windowed.
conclusion: those omega drivers made it all worse with my ati card. might be because they use an old catalyst source (7.12). the installed catalyst 8.11 behaved the way i always told, having vsync issues and so tearing.
i don't know if it just was removing the drivers from my system and install others, or if it really is something they've changed in catalyst 8.12, but
for now i have no tearing issues on win xp anymore, even with the absolute latest build (which has, as i positively noticed, the 1360x768 screen size settings again) .
