Sonicstar5: Ok so i discovered a few things.
If you want a vanilla style gameplay experience then why not try Quakespasm? And if you really don't want to use a source port then go with DOSBox for the original DOS experience (but I really don't recommend it). GLQuake also contributed to many other source ports, so why limit yourself to GLQuake considering the many issues and limitations it has? I remember using it the first time I played Quake and the gamma setting wouldn't work no matter what value I set it to, so I had to change my monitor settings each time. It doesn't support overbright lighting or fullbrights, and it has weaker coloured lighting effects than the software version. Further to this, GLQuake actually had regressions present (probably because it was unfinished). The first was WinQuake, also officially released. Interestingly enough, it wasn't the first source port either. Whilst it was released by id, they do not support it (and it never even reached a v1.0 release). But is it so wrong to want to use the original glquake? Actually, GLQuake is itself a source port.
Sonicstar5: Before you say anything, yes i know there are source ports i can use.
