Crazy CPU Usage with idle Vive (vrcompositor.exe)

[Dino [NG]]

If I start SteamVR and just let the Vive sit on the table without launching anything, I have vrcompositor.exe taking 15-20% CPU permanently, and also vrserver.exe taking almost 10%. Seems crazy high, is it the same for everyone?

If I try the same with the Rift (and SteamVR), vrcompositor, vrserver and the oculus process all only take 0-3% each.

Can anyone with a Vive check to see if it seems high for them too?

That's high I think, I'm running it right now and vrcompositor.exe is around 14% and vrserver.exe is about 3%. I'm running a i5 4790K.

Same for me. Constant 20% usage on a i7 4790k @ 4.7Ghz. Seems like one core is always at 100% load. Probably a serious bug.

There is a thread at reddit where multiple users report this: https://www.reddit.com/r/oculus/comments/4e810d/vive_using_5_times_more_cpu_than_rift_can_others/

Yeah, that's my thread :P
Seems to be a general issue... now we just need to find a fix!

Does anyone that's experiencing this high CPU usage also have issues with missed/dropped frames in Job Simulator (and to a lesser degree Fantastic Contraption) but no other games?

i5-2500k (4.6GHz) GTX 980 and I see crazy dropped frames in Job Simulator and Fantastic Contraption but other experience seem to play without issue (everything in The Lab, etc)

Just did a quick test, ran Job Simulator and looked/moved around a bit in the starting area where you can select a cartridge. Didn't drop a single frame, but my CPU isn't at 100% so the vrcompositor problem wouldn't limit the framerate.

Can confirm this. Also Reddit can: https://www.reddit.com/r/oculus/comments/4e810d/vive_using_5_times_more_cpu_than_rift_can_others/

I have the same problem on my 3570k @ 4.2Ghz. It's around 30% most of the time, even if I leave steamvr idling without a game open.

Yeah, as said on the reddit post I tried : Without a game running, with the base stations off, and the controller off, and the headset in standby mode (screen off).
So basically everything is off, nothing is running, nothing is tracking, .... and SteamVR still use one full core :/

+1 for this, vrcompositor.exe is using a full core when SteamVR is running regardless of what I'm doing.

[Virtual Jebus]

+1 for me too.

+1

In one of your Reddit threads a user posted this potential fix: https://www.reddit.com/r/Vive/comments/4emw9z/steamvr_use_100_of_1_cpu_core_permanently_when_a/d21nffr

Anyone else want to give it a try?
