I have the following:
A Latitude E6420
Intel Core i5-2520
Nvidia NVS 4200M
4 Gigs of Ram.
All of the components are onboard.
I do not know If I have updated the video drivers, it is a government computer so that may be complicated to do.
The screen does not go black when changing the resolution.
I do know that this is a common problem with Republic Commando as certain resolutions were not widely available when the game came out.
I have tried changing the resolution multiple times to no avail, I also tried the following sites solutions:http://www.blubrry.com/datacast/465791/how-to-set-a-custom-wide-screen-resolution-in-star-wars-republic-commando/http://forums.steampowered.com/forums/archive/index.php/t-1506206.html
Both of the sites suggest changing some info on the system.ini file in the game folder, but that still did nothing. Perhaps I was doing it wrong?
