Steam VR Heat

[Zsar]

Not sure whats going on here although it may be the norm for most.

I run all games fine cpu/gpu heats and i expect little more using VR, Oculus in this case but what i dont understand is the heat push from literally just starting steamvr , no game just hitting the button.

So idle is around 37-40 i open steam goes up few degress, i hit steamvr im almost at 67gpu and cpu fairly similar in numbers as a average, no game no nothing....

Same or similar for you guys?

Yes, I have an Oculus and have the same issue.

I have no idea what the cause is, but the Steam VR service "vr compositor" will use 100% of your GPU untill you put your HMD on, or trip the visor sensor. Once you trip the visor sensor, it will go back to normal with under a 10% GPU load.

You only have to do this once per session. Once you trip the visor sensor the GPU load will stay where it should even with the headset off untill you shutdown and restart Steam VR.

You can do the following to test it yourself...
1: Restart your PC
2: Open your taskmanager and sort processes by GPU load.
3: Start Steam
4: Start Steam VR
5: Watch your taskmanager, VR Compositor will use 100% of your GPU.
6: Now stick your hand in the visor to trip the sensor and watch the GPU load drop <10%

It strains my GPU to the point of coil whine. A coil whine I do not get under any other gaming or stress tests. I am sure it's not good for it.

I have reported this in the bug section months ago, but nothing ever came of it.

The only thing you can do is make sure you have your headset near and once you start Steam VR, make sure you stick your hand in the visor or put on the HMD right away.

TL;DR
Never start Steam VR and walk way. Always trip your visor sensor right after you start Steam VR unless you need to heat your house or feel like buying a new GPU a little sooner.

Cheers bud very informative and i tryed all that and you were right on the back of that , i found that you dont have to use steam Vr to play now in settings/devlopement theres a option to stop it when apps start, so basicly i can start a steam game now from oculus home it will intiate steam ofc but not steamvr, in this particular case im playing skyrimvr.

It doesnt take me over my normal numbers and cpu defantly a sizable drop.

Something seriously wrong with steamvr if it can just jump 25c just by starting it not even playing a game, but this negates it not having to run steamvr and oculus home same time feels lot better its a crazy resource hog.

I also dropped out of steamvr beta too just incase.

I atleast feel more stable like this.
