Heh Nvidia has always had issues with XI.

I didn't know the PC version had the Auras for Summons until I upgraded to an AMD/ATI card because the Nvidia cards refused to render the glowy effect. It didn't render it on GM's either.

I thought it was just a discrepancy between the PS2 and PC versions at the time. Then changing the card. "Bang" magically delicious and I see all the effects in full detail.
