In UDK, what causes FPS lag more, actuall geometry or textures?

GrungyStudios

Hello all. I'm currently working on a level in udk and it's starting to lag a bit because i have a lot of static meshes in the scene. Its lagging in game but lags more in the viewport. I'm thinking about optimizing my assets, but im wondering if i should reduce the amount of tri's, or reduce the size of my textures. What would reduce the lag more? Help would be greatly appreciated

Textures will always give you a much bigger MS boost than getting rid of triangles. Also make sure that you are not using overly complex materials as that too will give you performance issues.

Shader complexity and draw calls are probably the first things to cause lag.

The number of objects may be a bigger problem than texture size or polygon count.

Have you read the optimization guide?
