I am having, and have had, the same problem since I first downloaded the game, I cannot seem to change any system settings that affect graphics. I can change the options fine in the menu and in the UDKSystsemSettings file in ‘my games’. However, these changes are not taking effect in game, the same old crappy render settings are still active. My computer can handle higher settings so I know that’s not the problem.
I would just re-install the game but i am currently on a UNI connection that has 7 people on one wireless router. Speeds are not the best and i do not like to download a lot to reduce everyone-else’s speeds.
