hi i am using a 2900pro on widows 7 64 and although general performance is very good (i am running a amd quad core) my 3d performance is very poor souce games gane be jerky but cod5 is unplayable evern at its lowest settings and red alert 3 becomes unplayable once some units turn up!
i have reloaded the drivers and used the sames gpu in two different systems with the same problem. i have had no problems in xp.
Does anyone have any idea what i could do other than switch the onboard gcard on and give that a try?
Still the fact is they didn't move alot of 2900s, so there isn't much incentive to provide much support for them. Anyway the only thing you can do is write an email to MS and ATi to see if anyone takes time to even look at the problem for win 7 is final.
i thought it might be lack of support and hope it is! i know that the 2900pro was not a great card but untill widows 7 it was still pumping out mid to high at 1440x900 and i was hoping to get away with not upgrading it till w7 release date so i could go for the oem ver.
So what would be a good upgrade? i was thinking the 4770 (i have a crossfire mobo and a amd x4) but i hear bad things about the 128bit bus and the 4870 is only £120 or so. i may go crossfire at some point.
Well, since the 4770 uses GDDR5 on it's 128 bit bus it has similar bandwidth to the 4850 with it's GDDR3 on a 256 bit bus. Of course the 4850 has lower latency so that plays a part in it's generally small performance advantage over the 4770. Anyway the 4770 would be a significant upgrade over your single 2900 Pro and it would use a heck of alot less power. I think that you may as well wait for Win7 though since we should see some DX11 cards then. If you want a card now though you may as well get the 4770, or if it's out of stock get a 4850 for $5-10 more.
