Re: Quake won't do 640x480

Yeah, but; I am not just trying to make it run at high-res by any means possible. I want to know it this is normal and happens for everyone, or just me. And why it can't do 640x480 while Duke3D can do even 800x600 on pure dos, no extras loaded.

Although there will be no pc-bios, but will there still be a VGA- …
