Is there any way to ge this vsync signal? Canola and a great deal of SDL applications may use it to avoid tearing effect... actually we should do it in SDL to avoid duplicate work. while on 770 we rarely had tearing, but now, with faster software, we often update pixmaps while X is refreshing. X with backingstore would fix this, since it would handle double-buffering for us. -- Gustavo Sverzut Barbieri -------------------------------------- Jabber: barbieri at gmail.com MSN: barbieri at gmail.com ICQ#: 17249123 Skype: gsbarbieri Mobile: +55 (81) 9927 0010 Phone: +1 (347) 624 6296; 08122692 at sip.stanaphone.com GPG: 0xB640E1A2 @ wwwkeys.pgp.net
