Csonicgo Posted March 7, 2016 No, it doesn't. Only 320x200 and anything >= 320x240 is accepted. When that code was written, no one tested between 320x200 and 320x240, because, why would you? If anything, we should only allow custom resolutions for 320x240 and higher, and anything lower than that gets 320x200. I can't think of any PC screens that would go under that resolution. 0 Share this post Link to post
Gez Posted March 7, 2016 My guess is to emulate some weird console hardware. Like how PSX Doom displays in 256x240, but it loses about sixteen pixels of vertical resolution to overscan, so the useful window is 256x224. 0 Share this post Link to post

Those games also had custom graphics to match that fixed scale that never changed. 'Sides, Modern VGA doesn't work that way. 0 Share this post Link to post
Blastfrog Posted July 5, 2016 Gez said:My guess is to emulate some weird console hardware.That is precisely it. I want my game to render in a fixed 400x224 and upscale from that like Chocolate Doom does. I would of course provide an option to double that for people who can't stand low res. 0 Share this post Link to post
Quasar Posted July 5, 2016 Have you tested this on the latest git? There was a fix to a very critical routine called V_CopyRect that might have been implicated. 0 Share this post Link to post
