VR stuttering

[Licenceless]

Hello, had this ever since I got my G2.

As you can see the game just stutters a lot.
R7 5800X3D
RTX 3080 10GB
32GB ram 3200mhz
Game is installed on an NVME M.2 (1TB)
Some of my friends have same exact specs and also use G2 and have no problems. 
USB cable from G2 is connected via powered usb hub. It simply doesn't work when connected directly into the mobo, i think it's a known issue but i digress, my friends who have G2 also connect it through the hub and again, they have no issues so i don't think that is the issue.

so there a number of things to check:

1) Check your mouse polling rate and set it as low as it can go this was certainly an issue for a while 

2) environment, check for background processes, that might be causing the stutter, this could be anything so it might take a bit of investigation, what's your page file set to?

3) setting what are your setting both in DCS and in WMR/OpenXR 

4) not all hubs are equal, are there any other devices on that hub, what if you turn them off etc... 

5) if all else fails post your log files from DCS and someone more knowledgeable than me might be able to see something in them.

1 My mouse polling rate goes up to 1000Hz. I checked it on a website, can't find a way to adjust it without downloading bloatware. Also, as you can see in the video the issue doesn't appear when I move my mouse around the menu. If you can provide a way to adjust it through cmd that'd be great.
2 This is a fresh windows install, DCS and Discord, that's it. Page file is set to 62gb on the NVME the game is on. Main C drive is a 250gb SSD and I only have 150gb free, I could sacrifice the space for page file on the main C drive if you say it's a good idea.
3 DCS is running on lowest possible settings with preload radius at 60 000. 80% resolution. Only thing I did in WMR settings is disabling all audio in headset since I do not use inbuilt speakers.
4 hub is fully occupied because I have no space but I guess I can switch stuff around and maybe deactivate something I don't use. I used to run everything off my mobo but than i head an issue where mobo didn't have enough power for everything and thus I bought a hub
5 can you tell me how to provide a log file?

1) no i honestly couldn't really see your stutters on your video, bear in mind that YT drops things to a lower frame rate , which make the obvious to you look like nothing to everyone else

2) if it's a fresh windows install, windows 11 or 10 ?  if 11 make sure you have done this: Options to optimize gaming performance in Windows 11 - Microsoft Support, have you checked your XMP profile in BIOS, to make sure it is set appropriately, are you overclocking, if so how are your temps, 

3) then something is epically fubar on your PC because , if you are on the lowest settings you should be getting a better response rate than this, which means its not in DCS, when not in DCS but with Discord running what is your cpu utilisation looking like ? what's it like without discord running, what framerates (or frametimes if you know them) are you getting in DCS  ?

4) I'd turn some stuff off and just use it as a diagnostic, not as a fix

5) you can find your log files in (drive):\Users\(yourusername\Saved Games\DCS(.openbeta)\Logs, and you want dcs.log

 Stutters are at 0:03, 0:08 and 0:21, I guess one would call them freezes. It's a win10 install, bios updated to latest version, there is only one xmp profile for 3200mhz and to be honest I don't wanna mess with timings. No overclocking, I don't see any need with these specs. Cooling is sufficient, I have a big cpu cooler and enough case fans at pretty neutral pressure. 
Everything runs like butter on 4k (not ultra obviously, I tweak stuff for optimal eyecandy/fps), even other games in VR which are pretty intense like ACC runs very well, even with all the periferals in the hub.

So this is what I did:
1 removed all the periferals from usb hub and stuck them directly into the mobo
2 changed some settings (textures high, clutter grass on max, forest visibility on max, LOD switch at 0.8, shadows and terrain shadows flat or low, visibility on extreme, clouds on ultra preload is 60k flare is on texture filtering 16x)

Usb hub thing seemed to do the trickat first but as soon as I connected to 4ya PO (server was almost empty with 6 people on, june 3rd mission) for the second time, it began to freeze again (way less mind you). FPS in it self was never an issue, it was always high. CPU threadbound written in red very often, almost every frame it would flash between the yellow cpu bound and the red thread bound. The freezes occur when those green lines go all the way up, except for the last one cuz it froze every time i took a screenshot as well. And taking screenshots would F up frame time too. I actually couldn't see what the frame times were because the would constantly change so fast that I could barely read them, it was rapresented by two numbers and both kept switching betwen 0, 1 and 2 so my guess FTimes are very low

what Hz rate do you run the G2 at?

90, I tried 60 but it's to low, I get headaches from it

@Licenceless, you have lots of usb plug/unplug events in your log file. Go into your DCS controls settings and there will some buttons on the bottom right. Click the one to disable hotplugging devices. If you add a new controller in the future you can click the Rescan devices button. Having this enabled can cause stutters as DCS will be constantly scanning for new usb devices.
