Reactant Posted March 18, 2021 Share Posted March 18, 2021 (edited) It seems that everyone in Neos VR using the eye-tracker is having a large amount of CPU usage from SRanipalruntime. This amount varies between 8 to 25% per user. This CPU usage even persists while no longer using VR with the headset off. Interestingly, this percentage seems to be lower if mouth tracking hardware is installed. Small sample size, so this may just be coincidence. For myself, it is using 15-16% of my overclocked and water-cooled 10900k for eye-tracking only. I will be getting the mouth tracker when it is available to see if there is any change. Is it expected for the eye-tracker to use this much processing or is something wrong with the software? I confirmed that this happens before even launching a Neos. It will happen as soon as the eye-tracker is utilized. The eye calibrator will cause the same CPU usage. Edited March 18, 2021 by Reactant Link to comment Share on other sites More sharing options...
michael_wang Posted March 30, 2021 Share Posted March 30, 2021 Can you add code to test the fps of the client? because our test on our computer won't use more then 5% @Reactant Link to comment Share on other sites More sharing options...
testamundo Posted May 7, 2021 Share Posted May 7, 2021 Maybe SRanipal runtime ver1.3.2.0 has an high usage issue. Bellow quote from engineer found that runtime version 1.3.2.0 eat up the CPU performance massively. (Note: the below quote is saying about VIVE facial tracker user.)

zaqq Posted September 10, 2021 Share Posted September 10, 2021 Same here. The SRanipal is eating up so much of the CPU (i5-7500T) that the computer can't process the VR scene properly. By that I mean that the whole Unity Scene is lagging. Once I deactive the eye-tracking, it runs smoothly again. Can it really be that SRanipal is supposed to eat up that much CPU?

TheTheThe Posted September 21, 2021 Share Posted September 21, 2021 Did anyone end up finding a way to lower SRanipal? I am running into the same issue as all of you. Link to comment Share on other sites More sharing options...

No, not a proper solution at least. I'm suspecting my CPU (i5-7500T) is just not fit for SRanipal--what are you using? My work-around so far is to set affinity of the process to 2 cores. This helps a lot, but makes the eye-tracking lag a lot. Are you using this for gaming purposes or lab purposes, or...? Link to comment Share on other sites More sharing options...

Couldn't get onto a computer until now and the phone wouldn't let me login. I am using an i7-9700k. I sent a message into Vive Support and will update here when they respond. Hoping they have an answer for us. I appreciate your work around. Unfortunately from the sound of it, it will not help me out very much though if the eye tracking lags. I am using this to test programs, software, and a video game I have been working on. It definitely isn't being cause by the vive facial tracker, since with eye tracking disabled, I can track my mouth with the facial tracker at 4% usage. Eye tracking with facial is around 40 to 45% for me, and without facial tracker it is about 35% to 40%. Like others have said, even if I do not have the headset on my head, or any programs using it, it still drains 40% with the eye tracker. And based on what testamundo presented, 1.3.1 works just fine at about 8%. I think there is something wrong with the 1.3.2 version itself. Both you and I shouldn't have any problems even with our weaker processors. I am surprised after how many months nobody else has mentioned an issue though.

TheTheThe Posted September 22, 2021 Share Posted September 22, 2021 One thing I am curious about is, has anyone found the installer for 1.3.3 or is it only in SDK format? I would assume 1.3.3 would have a fix that would reduce the CPU requirement. Link to comment Share on other sites More sharing options...
zaqq Posted September 22, 2021 Share Posted September 22, 2021 You're right. This looks like a mistake. Anyone knows where the SDK v1.3.2 is to be found online? Link to comment Share on other sites More sharing options...
zaqq Posted September 27, 2021 Share Posted September 27, 2021 For anyone still struggling with the CPU bottleneck, this link should do the trick: https://hub.vive.com/en-US/download/VIVE_SRanipalInstaller_1.3.1.1.msi Uninstall the latest SRanipal installer and use the one above instead. Thanks to @TheTheThe. Link to comment Share on other sites More sharing options...
