Which of the here mentioned games are you refering to? I never got "Dominion Wars" to run on Geforce6/8/9 and XP. It didn't run on Win98se with GF6 either. Win98se and GF3 is the highest I got so far. Haven't tried GF4 or 5.
Which Patch version of the Game are you running?
Sorry, I should've said ST Dominion Wars, but I figured since it was right after your post that it would be clear. 😀
Yeah I've tried DS9 DW on a lot of cards myself. It does work with the Radeon X8x0 cards in XP. It works with GeForce FX too (I just tried it recently) in XP.
Athlon 64 X2 + Radeon X850 PCIe + XP
P4 3.2 + GeForce FX 5900U AGP + XP
Without FSAA, a Voodoo5 can run the game no problem. But if you want to use 4X AA, the X850 was the only card that I've tried that could do it well. I'm not sure why that is, but it's probably related to inefficient rendering. This game isn't exactly at the top of its class in programming quality. 😀
If the X850 can run the game, I am thinking that everything from a Radeon 9500 to the X850 should be able to. That whole range is rather similar overall. But I know that a Radeon 8500 will not work because the game has some problem with its implementation of dual display outputs (strange, I know.) I read that it will work if you hook up dual monitors (the game displays on the secondary!)
I use patch 1.04 because 1.05 changes all of the missions to some new ones, I think.
