This tweak will increase game responsiveness by forcing the rendered to finish the same frame instead of the next frame.
In English, this means that what you see on the screen will be closer to what is actually happening. The downside of this is that there is a rather large performance cost,
so don't use this tweak unless your computer can handle it.
To install this tweak, simply open your tribes.ini file located at: C:\Users\[youruser]\Documents\My Games\Tribes Ascend\TribesGame\Config\tribes.ini
After opening the file, locate DirectionalLightmaps=True (or false)
and paste the following directly below it:
OneFrameThreadLag=False
