Hihi everyone - I thought I'd pass on a bit of useful information I've found out in my experiences in Ryzom. After installing new drivers for my FX5700 (Omega's new drivers, and the 66.81), I noticed that most characters and some objects in the game became white shortly after logging in. This only happened when I was using the OpenGL client (since it runs about twice as fast as Direct3D). Wells, I downloaded RivaTuner and started playing with some of the settings, and found that (for me) the cause of this was the 'Intellisample' setting in the OpenGL part. If it was on either High Quality, or the notch to the right of 'High Quality', it'd do it. But, if it was set to 'High Performance' or the notch next to that, it wouldn't.
I dunno if this helps anyone at all, but I thought I'd post it since I'm really proud of myself for solving my problem

I realize this is only for nVidia cards, but perhaps there is a setting in the ATI drivers that would accomplish the same thing? If not, might be something to check in to

I also want to add that changing this setting in the Omega drivers solved the problem for them too (I'm using them now, 'cause they make stuff look better)
