Just purchased Duke Nukem and I'm getting tearing on my monitor (something I deeply hate). I've looked around and from what I've read DOS Box supports V sync. I added the following to the DOS Box config file (code was from another DOS Box config file) in the program files to Duke Nukem:

[vsync]
# vsyncmode -- Synchronize vsync timing to the host display. Requires calibration within dosbox.
# Supported are off,on,force.
# vsyncrate -- Vsync rate used if vsync is enabled.

vsyncmode=on
vsyncrate=60

On launching the game I was still getting tearing. I've tried changing the renderer via the GOG Graphic Mode Setup to OpenGL and Direct 3D but I am still getting tearing.

Can anyone out there help?

Thanks. That works pretty well and the game is now nice and v synced. Still hoping I can somehow get the original to v sync as the motion in EDuke32 feels off compared to the original :(

There's a way to get eDuke identical to that of the DOS version, but I'm unsure as to the settings.

Think I have it sorted out now. The auto run was turned on without me knowing it. When I turned it off the game felt just like the original version :)

Thanks for your help xx
