Maybe you should check task manager to find out if it is indeed UT3 using that CPU time. It doesn't matter how advanced a game is, no game should hit 100% load in the menu, or even in the game for that matter (except perhaps on a single core).
What are you using for a soundcard, and what version of the driver? (right click my computer, go to manage, device manage, right click sound device, properties)
Just a shot in the dark--but try uninstalling your sound device completely from the device manager, then run the game. If it changes, you have audio drivers that are horribly coded, and I would look for an update.
I would also be certain you are running the most current drivers for your video card (www.guru3d.com usually has the newest editions ready to DL).
As far as getting a screen shot, you can just hit the "print screen" key on the top right of your keyboard (near F12) then open up Paint, and paste it
Keep trying things, and posting, we will figure this out.
Just for argument's sake--uninstall your audio drivers completely, then tryin running it. I have the X-fi Fatal1ty Extremegamer and in my old PC I would have major lag issues with gaming with those drivers installed...worth a shot!
Well, you're not the only one who has 100% cpu usage during UT3, I used to get it on my E8400 as well. Constant 100% usage no matter what. I beleive it is the way the game is setup. As long as you are getting good fps, and your cpu isn't overheating I don't think you need to worry about it.
Wow, maybe it is truly CPU intensive beyond any other game I have seen. I forgot to test it on my machine, sorry!
I will try and test it on my machine tonight and check the CPU usage in-game. I haven't really played much UT, I bought it the weekend it came out just to try it and wasn't crazy about it. From what I remember it runs great on my PC, never thought to look at the CPU usage. I think I had only OC'd to 3.15ghz at that point as well...will have to see how it likes 4.05ghz
