Gun on Technical Gunner

HUD issue. When I use the gunner on the technical on any map my POV arms glitch into one place and don't move with the gun. Also, the sights on the gunner constantly phase between graphics. It goes into incredibly low quality, then gets a little better, and returns to the normal sight. This makes it really difficult to use the gunner in any match.

@mixxster Remove the custom config file you downloaded off of the internet:
Go to %LOCALAPPDATA%\Insurgency\Saved\Config\WindowsClient directory and remove "Engine.ini" file.
Once you start the game again, it will recreate the file and will use default config.

Also go to Steam, Steam Library, Insurgency:Sandstorm, right click on it, select Properties then open "Set Launch Options" and remove all if you have any.
