Well I installed the new 5.7 Catalyst drivers this morning, and low and behold:
I HAVE GLOWS!
Yessir, it seems that the new ATI drivers have rectified the glow problems that have been plauging the series since 4.11, at least for my 9600 Pro. I also noticed that if I leave out the Disable Vertex Buffer Objects line in my swkotor2.ini, Dantooine still seems to run fine. I haven't extensively tested it yet, but so far no lag.
So there you go, try it out. Hopefully it works as well for you as it did for me.
