UDK runs very slowly; advice on speed up of program?

Raptor-chan

Hello!

I've noticed that as I put more and more in my level, UDK starts to run very slowly. This is especially true when I go to test my level. It will run frame-by-frame with no fluidity and makes it very hard to test. I've already set my laptop performance settings on Best Performance in Windows and I shut down as many background programs that I don't need as I can. When running UDK, it's the only program running at the time. I get huge memory spikes as well, so I'm wondering if that could be the issue.

Computer Specs:
Microprocessor 2.13GHz Intel Core i3-330M Processor
Microprocessor Cache 3MB L3 Cache
Memory 4GB DDR3 System Memory (2 DIMM) (I have 8GB installed)
Memory Max 8192MB
Video Graphics Intel HD Graphics
Video Memory Up to 1696MB
Hard Drive 320GB (7200RPM)
Multimedia Drive LightScribe SuperMulti 8X DVD±R/RW with Double Layer Support
Display 15.6" Diagonal High-Definition LED HP BrightView Display (1366x768
Operating System:
Genuine Windows 7 Professional 64-bit

What else can I do to speed up testing my work in UDK and using UDK in general? Any help would be greatly appreciated. Thank you!

ok, so does UDK run slowly with only a blank/default level open? If it's running slow with the level, how many assets do you have placed and how heavy are they? (in other words, is it the application or your work that runs slow)

The problem it's mostly caused by your graphics card that is not really suitable for realtime 3D.
