Hi. I have a Radeon 9250 Agp 128mb / 64bit videocard. On parts of some games the graphic is glass like, somethings are transparent, viewed from an angle. I tried many drivers but nothing changed. Please write me only if you had such problem and if you managed to fix it. Thank you

I had strange lighting effects in some games when I used the drivers supplied with my 9250. After installing catalyst 6.1 drivers it all cleared up. Since that I've used Catalyst 6.2, 6.3 and 6.4 which also worked perfectly fine. Overheating can also cause abnormal effects but it's unlikely that would cause the problems you mentioned.

You can get Catalyst drivers Here

I tried the newest Catalyst(6.4), I have tried many Catalyst but it didnt changed anything.

Maybe you should give the brand of the card you're using and the the games it has problems with.

The card was manufactured by 3d Club. Games with the mentioned problems: GTA San Andreas, Midnight Club, Juiced

Or give a try to the Omega drivers, they are better than catalysts (no control center, no .net framework).
I use them and they work like a charm!
