Unreal Tournament III Tips and Information
This information is provided by DGUnreal.  Please do not copy this and post it elsewhere.

With permission, I am hosting this information for the UT 3 editor.  A big thanks to DGUnreal for allowing this useful information to live on.  I duplicated the tutorials as they were given to me.  There may be information that was going to be added by DGUnreal. But take this information on this page as completed.

Play-In-Editor Resolution

The Play-In-Editor windowed game defaults to a lower resolution such as 800x600.
This can be changed to a higher resolution by entering the setres console command:

- setres XxY eg. setres 1024x768

The PIE can also be preset to always start at a higher resolution by modifying the DefaultEngine.ini or UTEngine.ini found through the My Games path. Modify or add the following .ini entries under the [SystemSettingsEditor]:

resX=1024  (or the desired resolution)
resY=768     (or the desired resolution)

Additional Tips:

- Running Play-In-Editor is not the same as running the actual full-screen game.
- The ResX/ResY settings should only be added to the <My>Documents\My  Games\Unreal Tournament 3\UTGame\Config\UTEngine.ini.
- ResX/ResY should not contain values that are larger than the current screen resolution, or super-tiny (320x240 anyone?).
- Adding the ResX/ResY settings doesn't work on some systems for some odd  reason (to be determined).
- Do not modify the <Program Files>\Unreal Tournament  3\UTGame\Config\DefaultEngine.ini or the game and PIE may consistently crash.
- Do not modify the <Program Files>\Unreal Tournament  3\Engine\Config\BaseEngine.ini or the game and PIE may consistently crash.
- If you modify the BaseEngine.ini or DefaultEngine.ini and start suffering  crashes, re-installation is usually required.
