Performance

[svcoyle]

Everthing seemed to install okay. But the editor seems very slow compared to the UT3 editor and GOW editor. Is there a way to get back some performance through an .ini or config file?

The main issue is when i click on the viewport it takes a ton of time to update. It takes a minute in perspective mode to start moving but once i do its pretty fast until i click again if that makes any sense

my specs:
Inter(R) Core(TM)2 Quad CPU Q6600 @2.40GHz
4 GB Ram
Vista OS
Nvidia 9800 GT

This actually seems to be a mouse position issue. If i keep the mouse absolutley still i can zoom in and out no problem with the mouse wheel. If i am move the mouse slightly the mouse coordinates at the bottom take a few seconds to update before i can zoom again with the mouse wheel.

This issue is not just related to zooming but andthing you do when the mouse is moving

Hmm that's weird I have almost the same setup as you, except I'm running XP with an 8800 GT.
Have you tried updating your drivers?

I also had everything slow for me... but seems to be running fine now. By comparison to when it was slow, however, I have almost nothing open anymore. Shouldn't have been an issue, as I used to always do editing in UT3 with a billion things open (sometimes even games like L4D etc!) but UDK seems to slow heaps. For me, it seemed to be highly related to BSP :S

I have updated my drivers. Its still an issue

Last night it was actually working great for me with no mouse refresh issues. I closed the application and started it back up and the problem returned. I tried rebooting again and still have the issue.

This definatley has something to do with refresh of the viewport and the mouse. If i make the viewports extremley small it works okay. The bigger the viewport the slowert he mouse refreshes (you can see how slot the mouse coordinates update when you move the mouse around) Bot UT3 editor and GOW editor do not have this problem for me.

Anyone have any ideas??

This may seem extreme but I recommend if you're REALLY serious about using UDK to make games, give yourself a clean dev environment.

Backup, reformat, reinstall your OS.

Then under "environment variables" in your system settings (for windows), make sure the UDK directory is listed there.

Environment variables prioritizes certain folders as part of the OS environment so it's more integrated.

Thats exactly what I just did and everything seems to be working okay. Nothing works quite as well as a re-format haha.
