I have just updated the download links with the latest version, which really... really (really) improves on performance and efficiency. Here's some stats from my testing:
Setup: i7 laptop, average 2.4ghz router, fast resampling mode on, with Dear Esther game (Condor got me similar results, but I usually test with Dear Esther, as it is quicker to prepare)
With Xiaomi Mi2 phone, at 640x720 resolution: around 40fps with 25ms lag (that's pretty good, imho)
With Galaxy S4, at 960x1080 resolution: up to 20fps with 65ms lag (which is rather bad, but note that this is at higher resolution than Oculus Rift devkit 1!)
(The S4 gets better results, at same resolution, than the Mi2).
Your results will vary, depending on the hardware... a powerful desktop will definitely improve on those. Let me know!
