It won't let me change the resolution. I'm stuck at the default 1024x768. When I adjust it, it whacks everything out and all the menu buttons don't work right. When I hover the mouse over something it doesn't highlight it. Instead it highlights something else a ways over on the screen. When I get it to highlight to accept settings, it won't adjust the screen size. It does nothing.

r_width (your width resolution here!)
r_height (your height resolution here!)

Type those into your console (~) and hopefully that will fix it. Where I have my parentheses, replace with your monitor resolution native settings.

This happens to me a lot on Win7x64…..but then again it happened on Vista and XP to I tried everything at the time including the settings that Talon has mentioned but had no luck. Part of starting up the game now is adjusting the resolution. I just use the Tab and Enter keys on the menu screens to change to the required res.

You can also enter the desired resolution in an autoexec
