How to improve FPS

Hey everyone,

I got my Rift a few days ago. Now I would like to start working on my own little demo. I have experience in 3D modelling and texturing, but I do not know much about UDK. This weekend I started using it. But my pc is not the best, and I thought it would be good too know what features I should disable to get a good balance between performance and looks. The riftcoaster demo worked at about 55-60 fps. But when I compiled the simple UDK start up scene as a test, I just got about 30-40 FPS.

So my question basically is, what is the best way to improve performance?

I don't know too much things on UDK but if can be helpful i think that's like for Unity3D when you play a game in the Editor you have some less Fps.

So if you compile and make a build of the simple "start" UDK scene you'll probabily have 10-15 fps more than before and probably you'll get the same fps of the Rollercoaster.

I don't know if can be helpful,someone else will give you a more complete answer :D

Thanks for your replies :).

@cyberreality: I habe a Samsung R780 Laptop :S

Intel Core i7 620M @ 2.67GHz
8,00 GB Dual-Channel DDR3 @ 532MHz
1024MB GeForce GT 330M

Its not really good. But I can run the riftcoaster demo at 50-60 fps. So I thought I should be able to create my own simple demo too. I also read something about DX11 and DX9. I read that there are some performance issues with DX11. So I would like to switch back to DX9. But the problem is the "switch renderer" button in udk is grayed out :/.

@welby: Thanks for your answer. I did compile my game and I did get a little more fps, but it is not quite enough. I will just have to find the most computing intensive features and turn them off i guess :D .

AA should be off. It's a big FPS-killer. Vsync off will also help when framerates are under 60FPS.

Ok thanks! Where should I turn off AA? in WorldProperties or the ini files? I just found out how to create my own Post Processing Chain and I got a lot more fps! I'm slowly getting there :D.

Edit: Just remembered. Its the D3D9MSAA in the ini file right?
