AFAIK, the zbs hack was added by Keith originally. It has been in the driver as long as I know it. I wrote some other workaround that emitted state in a well defined order, which fixed some lockups. Maybe someone thought this would make the zbs hack unnecessary, but it looks like whoever it was, was wrong. > > I've played q3, ut2003 and ut2004 and ran gears.. all for about 5 mins > each... no problems.. > > switching OLD_PACKETS off and arrays on doesn't give a speedup with the > hack for zbs (it slows it down..) but adding flush less brings it back > nearly on par with OLD_PACKETS... > > There might be a better way to do this workaround... maybe ATI might know > something (docs don't say anything...) > > Dave. > -- | Felix K�hling <[EMAIL PROTECTED]> http://fxk.de.vu | | PGP Fingerprint: 6A3C 9566 5B30 DDED 73C3 B152 151C 5CC1 D888 E595 | ------------------------------------------------------- This SF.Net email is sponsored by: IntelliVIEW -- Interactive Reporting Tool for open source databases.
