ZDoom

I always play with jumping and crouching enabled, though I don't use it for skipping parts of a level, just dodging and backtracking easier. I might play through Icarus: Alien Vanguard as well, now that I think about it. Regardless, I eagerly look forward to when MagSigmaX releases the second beta ...

Do tell, I'm curious as to what your gonna play-test this with O: I plan on playing through these ones: Alien Vendetta, Back to Saturn X E1, DEUS VULT II: The First Edition, Hellcore 2.0, Hell Ground, New Doom Community Project 1, Newgothic - movement 1, Requiem, Sunder, UAC Ultra. As you can ...

It'll happen when it happens. That being said, I look forward to playing Beta 2, I loved the first beta, and plan to play the second beta through every decent map pack that I have.

720x480 is the smallest 16:10 resolution that I can use in GZDoom. I'm not sure if it's the smallest 16:10 resolution possible, but that's what I got from a quick check in the game itself. I hope that helps!
