Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

UDK-based games crash in fullscreen mode for non-admin users

I have installed and tried to run three different Unreal-based games on my computer, all of which have the same problem (namely Strike Vector, Hawken, and Antichamber; computer is less than a year old, runs Windows 8, all games purchased and downloaded through Valve's Steam service). When I launch the game, it gets as far as opening the game window and playing about a quarter-second of sound (indicating the "Made with Unreal" video clip is attempting to play). At this point the game window collapses and the program fails to proceed; no visuals of any kind are ever seen. Attempting to re-open the game window causes the issue to repeat itself. This only happens in fullscreen mode; playing in windowed mode causes no problems.

For security reasons, I do all my computer activity on a limited-user account rather than the default administrative account (which I have password protected). On the admin account, these games run fine in fullscreen mode, but on the limited account I keep running into this bug. Going into the games' settings through Windows and granting "Run as admin" privileges has gotten around the problem, but is only a temporary fix; the games do not seem to retain these privileges after closing down.

I have never had this problem with any other game engine, and it seems to be the main aspect these games have in common. I'm not a developer, so I don't have the knowledge base to be much more specific than this, but I think there's enough information here that respondents can reproduce the issue and examine it more closely. Hopefully someone here will have a better idea of what's going on and how to fix it permanently. Thank you for your time.
