Pellaeon

All up to date. I just set fullscreen to "false" in the ini files (as pointed out to me by another user) and the game started and plays fine. It just refuses to accept fullscreen on my mutli-monitor system. (Three different resolutions on all monitors, and no way (or desire) to cut them off when playing a game.) @razberry: Here's what TomatoSlayer told me: "Ren-X install folder > UDKGame > Config > UDKSystemSettings.ini > [systemSettings] section Set Fullscreen = False" Try this and see if RenX starts on your system.

That's damn hidden, but it worked! Thanks.

That's the exact same error I have. Do you, perchance, use more than one monitor?

I run a three-monitor setup. When I try to start Renegade X, all monitors go black, resolutions switch, then the game crashes with a "Could not initiate D3D device". I've seen this error with multiple games (even AAA ones) that seem to not be able to handle a multi-screen setup. Problem is... I can't find a ini file to change fullscreen to "false" anywhere and the game won't let me go into the in-game menu to change it from there. How can I change the game to windowed to tell it the correct resolution to use? And could you perhaps think about putting a non-GUI options menu (like in Skyrim or DX:HR) onto the launcher?
