apellisscot Posted February 1, 2021 Share Posted February 1, 2021 Hi everyone, I'm struggling with reaching the specified sampling rate of 120 Hz (8.33 ms) on a VIVE Pro Eye HMD. We use the SRanipal eye callback: SRanipal_Eye_v2.WrapperRegisterEyeDataCallback() in a script, derived from MonoBehaviour. The registered callback is only called every 14~16 ms, which leads to approx. 62 Hz. Way below the targeted 120 Hz. I think the PC specs are quite decent and should allow for 120 Hz sampling: Windows 10Pro Intel i7-10750H (specs can be found here) 32GB Ram GeForce RTX 2070 with Max-Q Design Following tool versions are used: SRanipal SDK & Runtime 188.8.131.52 Unity 2019.4.18f1 Pleas note that I am aware of these threads and articles, but did not find a explanation/solution that fits for me:Getting VerboseData at the fastest rate possible. - Vive Eye Tracking SDK - Community ForumAssessing Saccadic Eye Movements With Head-Mounted Display Virtual Reality Technology (nih.gov) Already many thanks, Scot Link to comment Share on other sites More sharing options...
