Settings for XWA on GeForce FX graphics cards
Someone on the LucasArts support forums found a post that I wasn't aware of that gives the graphics card and game settings to allow perfect graphics performance at all resolutions (without downloading the fonts fix) on nVidia GeForce FX series cards. I shall repeat what the post said here:
For your graphics card settings, in the "Performance and Quality" dialog, Application Control is "Off" on all settings. The other settings are as follows:
Conformant texture clamp=On
Game resolution should match your Windows desktop resolution in all cases, and you may set all detail settings to maximum.
