Boneworks and other Unity VR games with physics, can suffer from issues where noticeable stutter is observed, without any performance lost being observed. Has there been any work on this end for bone lab?

Basically title. In Unity games, specifically ones with physics objects held by the player (or in this case -- the player) the game can start lagging and your hands move around in, well, a laggin way, only it's not lag. Your computer will not show any problems occuring. Your GPU and CPU frame time graphs will be perfectly fine, maybe even with lots of headroom if you've got a good PC, but you will observe lag. Seems to be prevelant with AMD CPUs though people have reported it with Intel as well. Doesn't occur with Unreal Engine, like for hellsplit arena for instance, Or in Unity games without physics properties like Onward. But H3VR, Blade and Sorcery, Boneworks, and I suspect, Bonelab all have this issue.

As someone who's shelled out more money than he cares to admit on computer hardware to have a smooth VR experience, seeing lag occuring and not being able to turn down settings to fix it is pretty frustrating. You can find threads on the issue from 2 years ago and the issue is still alive today

damn I think you just solved my mystery regarding the weird stutters. Even with everything on low and lowest possible res scale of 0.5 (just for test) I would still experience these weird stutters. With so much perf. headroom, I could not wrap my head around it, but this makes total sense. And I am even experiencing occasional FPS drops when moving around. I5 9400F, RTX2060, playing via airlink 80Hz, Quest 2.

Same, rocking 3060 Ti and i5-11600K and I have to play on "Low" to get stable 90FPS...

Any solutions everyone?

Same issue here, not sure I feel it in other unity games though? I'm pretty sure population 1 is unity and I can crank my SS up to a 2.0(Rift cv1) on ultra without stutters ever really. Running a 3060 ti personally. Ain't the best looking game but still...

Airlink is another story. Streaming is gonna incur it's own hiccups separate from frame rate. It's not easy to troubleshoot without a direct cable connection to your PC

I totally get that airlink may cause issues of its own, however I do not have airlink problems in other games so I doubt it is related. I also tried the quest 2 native version and these weird stutters are there and this version ran even worse so I switched back to PC/Airlink. I also have a Rift S at my second place, will try that once possible. However I kinda got used to it and was still having a blast yesterday despite these weird stutters.

i have this issue with quest 2 on kiwi link cable. in debugger it shows constant 60 fps instead of 90 and drops thousands of frames. I have exact same problem with H3VR but it gets locked at 45 fps there.
However boneworks works perfectly with no issues. Is there any possible fix for it? Or the devs should be somehow fixing this?

We don't have the same issue. This issue will show absolutely zero change in framerate, but you're seeing change in framerate

[Anthrax360x]

I have this issue in a variety of Unity games in VR, including this one. Using a 3700x/3070 with 16gb RAM and installed on an ssd with pcie set to Gen 3 in my bios (set to auto causes gray outs in headset - known issue on x570 motherboards). Might try a bios update to see if that fixes the pcie Gen problem and maybe that'll help. I don't recall this issue occurring before I upgraded my PC around the time of Boneworks (4690k/1080).

This is all on the Index

Same issue in bonelab and blade and sorcery the game lag for 2sec and back to normal strangely there is no framerate drop in the headset . setting doesn't change anything .it happens when ennemy respawn ,look like a problem with unity when the engine load physics to a model. I have a decent rig 12900k rtx3080 reverb g2.i notice a subbtle amelioration when switching to a faster ram recently (ddr5 5600 mhz cl 28),but the problem is still there...

I think the issue might be related to using LHR cards, but NVIDIA will never admit their screw-up....

I'm in the same boat here guys. I've posted on the H3VR, VOTL VR and Boneworks discussions over the last year about this. I've tried everything under the sun to sort this stutter and nothing has worked. Deep dived into every bit of community generated help online over the last two years and as soon as I downloaded Bonelab and saw it was still happening I wanted to pack in VR for good.

I've got a 3080ti and an AMD 5900X running on an Index. Forget the insane hardware you need to run this game with decent graphics settings, that's a separate issue, but I was really hoping the version of Unity used to develop this game weeded out this stutter issue (if Unity truly is to blame). Sadly no dice. It completely destroys the immersion, and therefore the main selling point of VR. I would be really interested if a developer actually got to see this issue for themselves first had to comment on it.

Problem is, people do not believe our issue is real and always shake it off as a "driver" or whatever the hell they want issue...

Only us who have this annoying stutter know what we talk about.

I don't know if you guys have the same issue as mine, but i finally found a solution for me. In my case the games as bonelab and h3vr were v-synching to my 60hz monitor because i had a global v-synch option enabled in Nvidia control panel. As soon as i diabled it those games now run perfectly for me. Hope this helps someone in future.

Yes, this issue is also present in Bonelab as well. There likely will not be a fix to this issue unless Stress Level Zero updates their Marrow Physics Engine to a newer version of Unity. From my research, it is an issue with older versions of Unity. Something about delta frame times or variant frame times. This issue was supposedly fixed in Unity 2020 but I could not verify that. Here is a link to my post where I asked a similar question about the issue in the H3VR subreddit and the dev replied. Hope that answers your question. Makes me wonder if the devs for SLZ also have/live with this issue and are at least aware.

Yeah I read that too. Glad you got a dev to comment dude. Was so hoping Bonelab was developed on the newer version of Unity, but sadly it doesn't look to be the case.

Just out of interest, if I disable V-sync in the Nvidia control panel altogether (you can choose from use the 3D application setting (mine is set to this) / off / on / adaptive / adaptive (half refresh rate) / fast) would that make any difference? I use a TV (like a dork) for my monitor as my VR space is the living room and that has a refresh of 60Hz.
