Would it make me look like a fanboy if I said ATI drivers suck? They really do in my experience. That said, I haven't used ATI since Doom 3-era.
On the point of the game not looking much better than the original, you're right it doesn't... Dark Athena looks a good bit better, but not the original. It does however have a lot of cool new particle effects and motion blur/depth of field stuff, and maybe that is why it requires more card than you are offering.
My point was, the 2600XT it calls for on the ATI end of the spectrum is actually a much slower card than my X1950Pro, it's just a newer model that may not have been relegated to Legacy support like mine was.
I certainly am not one that's quick to call anyone an Nvidia fanboy merely for pointing out ATI is not as good at nor as long term supportive with their driver writing. I myself have been on ATI for the last 4.5 of my 7.5 yrs of PC gaming and I can definitely attest to that being more fact than fiction.
As for motion blur and depth of field, that is post processing effects, not handled with the main graphics rendering. As far as I know it's done via the CPU, but I could be wrong. At any rate, I don't see why they would make the spec higher (Pentium D min, vs P 4) due to that alone when in many games those are effects you can turn off in the menu or config files.
Not all is bad with having switched to the ATI driver though. I can now play Wolverine without the graphics glitch I was getting covering the whole screen repeatedly during fights. Thus, I guess I'm going to have to stick with their drivers, unless Angel "Omegaman" Trinidad starts writing the Omegas again.
I was really looking forward to playing Assault on Dark Athena, so Wolverine playing better is not much consolation at this point.
