i’ve got some serious jitter after the last PiTool Update and Firmware upgrade. As you can see here in this Video:
The Video is edited, because i can not record the jitter with screen capture. This means the tracking is fine. It is just something inside my Pimax 5K+ which causes the Image to “jump” back for a second.
This is vertiginous and make me dizzy =(

I had the same problem when I upgraded to the latest PiTool and firmware from v184.108.40.206. I observed it when I was just looking around in Elite. It was so bad, I had to revert back both the PiTool and the firmware.
I have Ryzen 5 2600X, GTX 1080Ti and 16GB RAM, I wonder if this might be a coincidence. The old PiTool and FW were smooth (in Elite), without any problem.
@Heliosurge thanks for the response, I will get 16GB 3600Mhz soon. The CPU isn’t even 50% loaded while gaming, so i do not think this is a CPU bottle neck.
I found out that, when there is an spike in frame times, the jitter occures.
So i guess the Headset wants to repeat the last frame, if there is no new frame present? But it is not repeating the last frame, but the pre(pre) last frame. So it looks like the image is jumping “back”.
Please stop making people upgrade their RAM and CPU even though it allways a bit better with faster components, it’s not allways the source of their issues.
Im running an “ancient” i7 3770K @4.6GHz with 32GB DDR3 1600MHz RAM @2000MHz a GTX 1080Ti and im not having jitter or bad aliasing as you describe. Last time I saw some hicckups / stutters in ED I was able to get rid of them by disabling CoreParking👍
Just saying, more, bigger, better, expensive is not allways the solution
Iirc Bottleneck Calc is an online website that just looks at your hardware components, and then “by some definitions” says if it thinks some parts are too slow.
it does not take OC of components into consideration and so on.
Just make sure to run pitool once.
Then make sure the client is not running at all, and just use steamvr after.
I use to get stutter on beta .180 and someone suggested to exit Pitool software after setting whatever your settings are, then run steamvr
(I make sure to uncheck all 3 boxes in the pitool settings/generals tab)
when i did this, all stutter that was introduced in .180 went away for me.
it was super rare that i seen it come back, and that was sometimes in VRchat.
So, i do this all the time now, even on .197.
my Specs are:
CPU: Intel Core i7-4790k @ 4.6GHZ
GPU: MSI GeForce RTX 2080 SEA HAWK X (OC: +100 core +1000 memory +104% Power)
Ram: Corsair Vengeance Pro 16GB DDR3 2400mhz
Motherboard: ASUS MAXIMUS VII HERO Z97
Liquid Cooler: Corsairs H100i
OS: Windows 10 Pro 64Bit
Sound Card: Sound BlasterX AE-5
Another source of jitter/stutter might be nVidia Experience.
Personally, I only install the nVidia drivers, not the Experience app. That app does things like creating a 5 min video buffer (it’s always recording) so that you can save a video of something amazing in your game, after it actually happened. If you do want to use the app, be sure to disable unneeded features during a VR session.
