Holy Crap. Quake!

Just so you know, you are not alone with the love of the original look.

always nice to know

You can make opengl quake engines look more like 'software-rendered' Quake by setting gl_texturemode gl_nearest.

Yes and it looks gorgeous!
GL_NEAREST_MIPMAP_LINEAR is even better as it reduces pixel mess in the distance.
Filtered textures look so ugly.

is there/whats the difference between GLQuake and WinQuake?

Also someone tell me how to upload pictures from my folders onto here. please.

I just finished part 1 of something I had half done of my harddisk for ages, some series showing the differences. Software vs GLQuake: Texture filtering
No idea when I will finish the later parts.
