I use the latest ATI drivers.
I then use the DH mobility modder
on the latest ATI drivers to create Mobility-compatible drivers. These work on my T42P (Mobility FireGL T2) & my X31 (Mobility Radeon)
FYI: once you do the mod, the drivers don't work on regular cards. Therefore, I need to have the original drivers for the 9800XT, and a copy of the drivers for the Mobility Mod.
Also, Omega drivers
support both standard cards (9800XT) and mobility cards (FireGL T2).
The only issue I've run into as far as games go is that CS requires DirectX. The OpenGL won't work on it. (Although it does work with Q3A...not sure if I have tried any other OGL-only games).
Ghosting only occurred in HL based games (CS). However, I only play CS @ LANs...and it's not terribly annoying. Just affect textures, not the players themselves (from what I noticed, at least).
I came from a T41P which had no ghosting. The T42P has a little more, but certainly isn't something that is a distraction to me.
UT2004, FarCry, BF42, Q3A all work and look great.
Of course...I'm used to working on a miriad of displays(Dell 2000FP UXGA @ LANs, dual Dell 2001FP UXGA at home, the T42P UXGA Flexview, and the X31's XGA 12.1)...so I can tune out ghosting pretty well.
