I am having pretty much the same problem trying to run Quake3 and get the same evil “… could not load GL subsystem” message. OS = Windows NT 4.0 with all the latest Direct x stuff. Have tried editing the win.ini file but there is no dva string. There is a string that reads “; for 16-bit app support” have tried altering and deleting that line, but nothing works. Have also tried setting color to 16 bit, but that option is not available. Any hints woul be greatly appreciated.
