Yeah, good idea to keep the bloatware minimal.

Yes, it’s always a good idea to run only the programs you need, not all the junk that companies want to install on your PC.

I do not have it installed, yet I observed massive stutter (would probably rather call it that than jitter) after I upgraded to the latest beta PiTool and firmware. Saw it Elite when turning around my head. The old version run smoothly.
I had very old PiTool version (1.0.1.132) so maybe people who were coming from the newer versions, were already partly conditioned to it, but for me it was clear deal breaker. I had to revert both PiTool and firmware back to the old version and now, it works fine again.

I don’t see any stutter in Elite D using PiTool 197. I’m not used to seeing stutter; it’s not pressent.
I wonder if more CPU cores helps? My i7 8700K has 6 cores (12 threads). When I play ED, I often have several other programs running: Media Player for background music, Voice Attack, Steam, EDMarketConnector, and sometimes fpsVR and Edge (browser). Even with all of that in the background, I don’t see stutter.
What about Smart Smoothing? Could that be an issue? I keep it off. I did find that FFR Conservative mode was helpful to boost my fps to 80 Hz (most of the time).

I have also 6-cores (Ryzen 5 2600X) and I think the CPU is not a bottleneck, as I am not running anything in the background while gaming.
I have all “advanced” features turned off, because I realized that even if ED does not hit 90Hz all the time (or at all), it runs pretty smooth at whatever framerate it runs. Really. I believe it might be partially because of its relatively slow scene changes (like cruising in the space, or approaching the objects), but even in combat I do not feel handicapped by the refresh, nor experience any stutter. (And I am running the headset at 90Hz, actually never changed that).

You might want to try FFR at Conservative. In 197, it’s not as distracting (except for orbit lines) and I found that it really helps boost the framerate. Also, you might try lowering some of the in-game settings and/or the SteamVR SS. One other thing I do, if I’m going to be driving the SRV or will be around stations a lot, is to lower the in-game HMD SS to .85 or .75 until I’m back in deep space. Even when the framerate is low, I don’t see what I’d call stutter. Moving my head is still smooth in VR, but it’s like watching a low framerate video.

I do not think FFR would work on my 1080Ti.

You still may want to try what @douglaster posted about assigning vr processes to later cores. I think he said prio can automate this for startups?

I just remember that I ever found this issue when I use vive on some game such as Apex Construct.
That time, it caused by bug of reprojection in steamvr.
But not sure about this case, may be about Smart Smoothing.

Yeah, that’s too bad.
I am suspect that the new firmware using more power on headset or not? it look I can see the blinking easier.
Strange. The new driver seems good to me. I see a ~10% framerate increase, so I’m sticking with it.
I’ve only seen 2 issues: It’s quite difficult to successfully change the refresh rate and the chevron color keeps changing back to green (which is a very minor issue). I wonder how much testing Pimax did on different PC builds. Too little, imo.

Neal, one thing maybe to stress out. The people complaining are running P5k+, while you have P8k (which runs at different refresh). I believe Pimax tried to change the frame timing and the new one does not work that well for some folks.
There were people (I believe it was @Fitzy) suggesting that this is related to “low GPU utilization bug” and Pimax attempts to fix.

Yeah. Pimax have introduced and fixed this exact bug before, then reintroduced it. It affects a significant subset of users and can be resolved using the old Pitool and firmware. Some users are okay and don’t get it. But the ones who have it, definitely have it and Pitool is at fault.
Could be 5k users only as Risa says.
I actually have the same CPU as you Neal!

So i found the reason for the “Jitter”. I experimented with some different VR Games and every time the frametimes get close to 11.1ms (90hz) i experience this Jitter.
So its every time the Framerate dips below 90fps.
BUT if the frametime is consistent over 11.1ms lets say 15ms to 18ms, than its also perfectly fine no Jitter!
So something is wrong, if we getting frametimes just under or over 11.1ms @90hz.

You might try disabling Smart Smoothing if it’s on. This could explain why I haven’t seen any jitter: My 8K maxes out at 80 Hz.

Experienced that kind of behavior with the other brand headset - whenever the smoothing kicked in, got a lag spike. Worst situation was when the fps was right on the edge so the smoothing kept switching on-off-on-off and so on.
Ended up setting the hz to max and forced the smoothing always on.

As there isn’t a “always on” toggle for Smart Smoothing what I do is up the supersampling in SteamVR and/or PiTool or up the graphic settings in-game too keep Smart Smoothing on.

Yes sounds like my problem, but there is no smart smoothing always on in the PiTool 179 or is it?

I think not. Doc have the solution just above.
