As I've stated in previous mailings, I've started having problems getting HalfLife to run under Wine - while at one time I was able to complete all of HalfLife - Opposing Force running under Wine, now I am unable to get the textures to render correctly.
I have more information - I subscribed to Transgaming, downloaded the current WineX, installed HalfLife under it, and it works correctly.
So, that would tend to exonerate my libGL, my system, and HalfLife, and leave only Wine as the suspect in the problem.
So, the question is "What is the difference between the WineX OpenGL library and the Wine OpenGL library?"
I hope to do more research on this over the weekend, but thought I'd post this now in case it rang any bells with somebody else.
