I'm sure Rogério wouldn't mind loading the bus more in favour of the CPU. :) But anyway, limiting bus traffic to one transfer per frame shouldn't be hard either. > ATI wouldn't likely recommend uncached/guarded or not using > the hardware IDCT either though. > > If this has any chance of getting me 1600x1024 at 24-bit on > my Mac Cube, then I like it. The bandwidth between the chip and its video RAM matters for this, the bus bandwidth only limits the size or fps of the video images. -- Earthling Michel Dänzer (MrCooper)/ Debian GNU/Linux (powerpc) developer XFree86 and DRI project member / CS student, Free Software enthusiast -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
