Comments: While this chipset is the top pick
by the PC2JAMMA project, and comes highly recommended by many,
I simply can't give it a great review. Given its high status,
I spent a lot of time getting to know each and every one of
the cards above and while their performance did differ a little,
they all fell pray to the exact same problems. Occasionally
a mode, for no recognizable reason, will go out of sync. It's
like looking at an image through a very thin waterfall. Sometimes
a slight adjustment in the modeline will bring the mode back
into sync, however, this doesn't always work.
All cards with this chipset support interlace
modes, though Matrox's G400, SIS's 6326, and particularly
Trident's BladeT64 cards produce interlace modes of similar
or better quality. As the problems with this card are intermittent,
trying to sort out what's actually happening isn't very easy.
But from my testing, it didn't seem to be related to pclock
values, dot clock multiples (VESA char width, 4 or 8), hclock,
or vsync. This card isn't AGP 2.0 compliant and it doesn't
support 32bit color in DOS. For those who really want an ATI
card, cards with the Rage 128 chipset are a _much_ better
alternative. They don't fall pray to any of these issues,
support 32bit color in DOS and are typically AGP 2.0 compliant.
Note: several versions of AdvanceMAME were
used for testing, dating back to 0.56. The problems listed
above affected all releases tested.
