Glide is just one of the drivers. There's also OpenGL and "SDL GL" whatever that is. I have tried the latter but I find it doesn't work as well. I'm not sure why it doesn't link against libGL. The other good news is that new plugins can be built. The original renderers have framerate issues on modern machines but there is an enhanced renderer by Chris Dohnal. I did manage to build a recent version of his renderer for Linux once but I had to install Debian Sarge in a VM in order to do it!
