100% sure. I distinctly remember using the lowest resolution, and lowering the screen size down just to play. Same with Half-Life, no way I could get such a high resolution. At most, I would try 512×384. You mean to say it’s all some sort of false memory? No… I’m pretty sure I got Quake working at a 320×200 in magic dosbox running win95. That too I would use the lowest resolution and turn down the screen size back in the day.
