What config needed for 75fps in WebGL application?

I want to make webgl application (using ThreeJS) for Oculus Rift DK2. DK2 need to get 75fps rendering output for the best view. But I have problem with it: one PC output 75fps, another - 60fps only.

My PC configs:

  1. PC1 (outputs 75fps)
    • Intel Core i5
    • 10Gb DDR3
    • GeForce GTX 650
    • Windows 10
    • Firefox Nighty with WebVR addon
  2. PC2 (outputs 60fps)
    • Intel Core i7
    • 16Gb DDR3
    • GeForce GTX 650
    • Windows 7
    • Firefox Nighty with WebVR addon

What affects to config PC2 that doesn't output 75fps?

Solution

  • Here are some suggestions:

    • Oculus runtime 0.8 (direct mode only)
    • Geforce drivers v.358.70-beta (as per the 0.8 runtime instructions)
    • Firefox Nightly w/ following flags (set via about:config)
      • dom.vr.enabled: true
      • gfx.vr.mirror-texture: true
      • layout.frame_rate: 75 (to match DK2 refresh)
