Judder in my Unity project

I started playing around in Unity with the idea of making a demo. The test scene i made is looking pretty good, but I can't get it to run without judder. The problem is that I have judder issues with quite many DK2 demos so I can't be sure if this is just my system or the demo itself causing it. So I'm asking if people could quickly test it and let me know if they are having judder issues as well. The demo might require a pretty good GPU in order to run properly.

    your daleks look like they are very high poly - the chairs don't feel very optimized too. if all your spotlights are creating high res shadows this little scene is full of performance eaters.
    try to remove the shadows first, just to judge the impact. And/Or remove the Daleks.
    When going VR it is best to start with a simple scene and then add objects until your FPS fall below 80, then try to see if you can optimize your scene to make room for more content. VR is a battle for performance, not visual fidelity - and your scene looks gorgeous, but too gorgeous for VR ;)

    occlusion culling should help a lot too, but you need to spend some time learning how it works.


    Right now I don't have shadows turned on in any of the lights. I'm getting almost 75 fps. The ideal solution I wish I had was one directional light that pointed down and would only add specular highlights. Then I could just bake all of the real lights and still have decent specular highlihgts on objects. Maybe I could use a enviroment reflection map that simulated this. I also do use occulsion culling.

    I'm guessing the 2 big issues with the scene are the Dalek model and the high value of point lights per pixel. The default value is 2 and I have to use 5 in order to get things to look decen't.

    maybe have a look at mesh baker - it also might help you with occlusion culling being more effective. I was able to reduce drawcalls to a minimum with great performance results.
