I just upgraded from an NVidia 128Mb graphics card to an ATI Radeon 9250 256Mb. Mostly improved performance with SH3, esp UZO, but now in clear wx I ger random flickering black polygons on the horizon. Anyone else seen this, anyone else know how to fix it? I am running SH3 v1.04.

What nvidia card did you upgrade from? It's hard to imagine any 128meg card that wouldn't be better than a 9250 or at least equal to it. A Radeon 9250 is a very old, very slow card. The 256megs of ram is meaningless-- any game that actually requires 256megs of texture memory will be far beyond the 9250's meager capabilities anyway. It's just marketing. People who don't know better say "OOOOHHH, 256 megs for only $79 (or whatever . . . hope you didn't pay more than that). Even a 128 meg 9550 is many times the card. In fact, a Radeon 8500 will most likely run rings around it.

Anyway, get the latest drivers and hope for the best.

Yep, I have the same problem with my ATI card and the black triangles. It's a known problem for some of us.

Upgrading to the latest ATI or OMEGA drivers didn't help in my case, maybe you'll have more luck... http://forums.ubi.com/groupee_common/emoticons/icon_rolleyes.gif

The triangles don't bother me tooo much anyway...

I have an old ATI 9000 and also get these artifacts.

As for your 9250 card, as long as it isn't the "SE" version, you will be getting 6.4GB/s transfer rate. Which isn't bad but isn't near a high quality level.

As for the comparaison between the 9250 and the 9550, they are the same card except that the 9550 is a direct X 9.0 card where as the 9250 is direct x8.0 card.
Same core and mememory clocks. But all bets are off if either is an SE edition (ANY ATI SE edition card will have half the transfer rate since they use 64 bit interface.)

Even the 9600SE is slower than the 9250.
