Using the ‘jit.gl.render.vblsync.maxpat’in the jitter examples folder I get tearing on a secondary monitor using Radeon 3870 on Windows XP PRO. Investigating a little further if I fullscreen on my main monitor no tearing. I need no tearing on the secondary so that I have access to my task bar when deving.
My inclination is that it has something to do with the AVIVO video control options within the Radeon driver, since it handles special routines on your secondary monitor when fullscreening. I’ve searched the forums extensively and tried the various solutions (horizontal span, changing the size of the jit.window ect) and no luck.
Has cycling explored compatibility issues with the newer generation ATI Radeon 3870 / 4870 cards within XP?
Athlon 64 4800
Radeon 3870 or 4870 with latest driver
