100% CPU utilisation in CV1

[CMDR_JAMESONS]

I've recently started to see 100% CPU utilisation in certain situations whilst using my rift. Situations mainly include RES and stations. Seems to be worse in open. GPU only at about 50% at this point and FPS drops to 50-70 as a result of CPU bottleneck.

6600k i5 @ 4.6Ghz
980ti Strix OC @ 1.46Ghz
16GB Ram
WIN 10
CV1
Playing directly from launcher with Oculus home open.

Anyone else seeing this?

Maybe a network bottleneck causing over use of CPU?

Was it doing it before?

RES sites and stations are two of the heaviest geometry areas in the game. Running in VR imposes deadlines on certain chunks of the render pipeline. Sounds like your CPU isn't quite completing the geometry calcs before the GPU deadline for the Rift.

Without new geometry, the GPU will default over to running the Asyncronous Time Warp and skew the last frame it had rendered based on the newer tracking data from your head position. Given that only take a tiny 0.6ms (out of the total 11ms you have to complete a frame, and you see that's why the GPU utilisation drops to ~50%. While the poor CPU is struggling to get the next frame started and done.

I see high CPU utilisation in stations, and lower frame rates too. Even with a 1080GTX, as my CPU is a 3770K at 3.5GHz (it ramps up to about 3.7 when under high load in VR).

I do close any Oculus Home alerts, and minimise the window when in VR. I close the ED launcher window too, so there's a minimum of 'other stuff' on the screen.

In your case, I would drop the detail settings while running the Oculus Debug Tool to see how it affects the CPU timing. There's HUD's for checking the CPU time to calc and the GPU load too.

Cut the ED options down - anything that will increase the actual geometry load - just to see if the problem goes away. Try running the VR low preset, drop world and object detail to low, drop ambient occlusion off, draw distance. See if freeing the cpou from the geomtery load makes a difference and then bring up the detail.

Check out the sticky at the top of this forum about the audio. Play around with lowering the audio settings in the file described there.

Thanks but I previously optimised the settings a few locations including stations RES and Eng bases to ensure good framerate. It seems something has changed. Also I can visit the same station and it doesn't always do this. I can tell ATW has kicked in though and check and the CPU is limiting things. Very odd...

did you find a reason?

From my experience fps changes from one day to the next in the same system/station just becuase of different frontier server loading due to different number of ships/activity around at given moment.
