Is there anyway to enable V-sync in DOS box? If so, how can it be done? I notice some v sync "tearing" in some dos games. Tunnels of Armageddon show cases this problem well.

Enabling v sync would help, does anyone know how it can be done?

Also I noticed that in 1080p resolution (1920x1080) which is the native resolution of my screen, the game doesn't fill out the entire screen. It almost fills it out, but it does leave a few black borders on the side. There seems to be no way to stretch it out so it fills out the entire screen, except use a non standard resolution like 1600x1200. I would prefer to use the native resolution, since it makes the upscaling look the nicest.

Does anyone have any suggestions on how I can scale to full screen at 1920x1080 mode?

My does box version is 0.73 and the frontend I use is D Fend 0.93
