Cant fix the occasional stutter, suggestions? (Update, Logs included!!)

Ive had this stutter now for over a week and ive tried almost everything to fix it. Ive reinstalled graphics drivers (wiped with ddu), ive moved things to different USB ports and i have updated my drivers. I have a good system (6600k @4.5ghz, 1080ti, 16gb of ram and ssd's) so im thinking its not system speed related. I pulled up the performance overlay and it looks like im dropping a frame when the stutter happens. This stutter happens in iRacing and the oculus home screen. Any suggestions?

Doubt its the ram but ill run a memtest on it. Its 16gb of ddr4 3000. The forum is littered with these kind of post so im really doubting its my computer at this point. According to afterburner (yes i closed this to eliminate it as an issue), my pc is barely being utilized. Looks like the gpu is running at 50% as well as my cpu (6600k @ 4.5ghz). Im talking with Oculus who wants me to record a video of my rift stuttering. How im going to do that i have no idea.

Is it in unity based games/apps?


Its everything. I can open the lost frame app in the debugging tool and just sit at the oculus home screen. Its most noticeable when moving but even if i sit still, the screen sort of moves like its dropping a frame or having a tracking issue. I ran iRacing last night for 5 minutes and it recorded 205 lost frames in 5 minutes.

I feel your pain RiftUser83.  I'm not a computer tech type of person so I had a PC store build my rig about a year ago specifically for the Rift, and I have never had optimal performance with it. There are a few games that always work perfectly but the majority of the big titles have always had some type of performance hick ups and problems.  I even about two months ago left it with the PC shop to see if they could figure it out and they went through oculus support back-and-forth for about three weeks and tried all possible methods of fixing my stutters, hitches, and the like by Oculus' recommendations, and still having problems. The shop finally gave up and they know what they are doing. They seem to think it's either the Oculus updates, or the Nvidia drivers, but to be honest....I think it's the later.

I wish there was a magical fix, and hopefully one of these days they will figure it out and give us all an equal performance experience we deserve.

I know you shuffled USB slots but have you considered power draw? The Rift + sensors pull a lot off the USB's. I had a similar stuttering issue in a couple games (not all or even most) until I had nothing plugged into that USB panel except the rift itself. This is with a brand new high end build. Between the overclocked R5 1600x and a 1080 TI, the motherboard just couldn't feed the rift off the back panel with the sensors, keyboard and so on all back there too. Moving half of it to the front panel (direct power from PSU) solved the issue.

And yes, this seems to be a common problem. I'd given more or less the same answer to several threads over the past week. No word on if it has helped anyone though.

Edit: I also had to bump voltage a little on that part of the motherboard in the BIOS, but that's likely just an MSI issue.

I ordered the usb 3.0 card that Oculus recommended in several post i have found. It should be here Monday and im hoping it will fix the issue. If not i guess ill push to send it in for inspection. Thanks for all the replies.

lost frames are from the CPU not keeping up with the GPU... the cpu doesnt process the frame... and the GPU drops it

keep at it you will be a computer whizz in no time

My CPU seems like its only working at 50% load on the Oculus home screen. It seems to have plenty of power in reserve.

to totally bugfix something I always make sure its not a software problem first..... IE re-install all the software from windows > +up

then can be sure if all fresh software and its still happening then its faulty hardware.... start swapping out peices of hardware one by 1....

until only a few things left to try and then can be sure its those things

you are going to need to test the headset on another computer.... and RAM and GPU swap out

this is why do software re-install first to make sure its not just software that bugs out really easy! and often does
