The IMAGEON 100 will never be a stellar performer. It was designed for low cost and low power, not high performance. It does have a simple blitter, and it has a reasonable YUV overlay, but the motion compensation acceleration is only slightly better than straight software. There is an O/S-independent (theoretically) acceleration layer for the IMAGEONs, but it is ATI-proprietary, and to my knowledge is only released to their partners. >So please if anyone from ATI is listening, please consider to support an >XFree86 driver development! Didn't we just see this movie? What's their incentive to do so? The people who are selling IMAGEON-based devices want Windows CE, and ATI is happy to help those people with CE drivers. Your plea is well-intentioned, but if I were you, I would not hold my breath. -- - Tim Roberts, [EMAIL PROTECTED] Providenza & Boekelheide, Inc. _______________________________________________ Devel mailing list [EMAIL PROTECTED] http://XFree86.Org/mailman/listinfo/devel
