New SimHaptic for bass shakers works great!
Panzerlang replied to Peedee's topic in PC Hardware and Related Software
The SimHaptic line in the lua file vanished by itself in my case. Reinstall SimHaptic. -
I was rather interested in his detailed description of dialling in the physical fit, which seemed to eradicate most of the issues MRTV described (who didn't mention any of that). Could it have been that simple?
-
Couldn't be more opposite to MRTV's one.

No, I don't. But I have no idea how the Quest Pro works in that regard. I never used to have to re-centre the headset, now I have to do it every time I fire it up. It's pretty quick, just hold down the Pimax logoed button on the controller, wait for the green circle thing to do it's turn, keep the button pressed until the short vibe indicates the controller is shutting down and carry on.

With me (Pimax OG Crystal), that happens until I centre the headset (that's separate from centering VR and/or NeckSafer). It's not a bug in NeckSafer.

For the squished XRNS panel issue right click on its desktop icon, then: Properties -> Compatibility -> High DPI Settings -> Override scaling behavior performed by System. Simple tool to check your six - Page 29 - Virtual Reality and VR Controllers - IL-2 Sturmovik Forum

And this is the company that asks people not to send parcels with signature required. Red flags anyone? Or just me, being 'paranoid' again. Where's Calvin these days?

Hunting for the stutter-free VR experience.

I covered my definition in this video (posted in this thread a few days ago). -
Now delayed to late Feb or March.

Hunting for the stutter-free VR experience.
Panzerlang replied to Panzerlang's topic in Virtual Reality
Well, maybe it's apples and oranges but IL2 (single core) thrashes the GPU quite nicely but barely touches the CPU, assuming the Game Bar widget is accurate. That reports 7% CPU usage (highest I saw at least). Yeah, kind of hard to believe the widget's accuracy, one would think 87% GPU would be pushing at least one core on the CPU way higher than 7% (I'm assuming the GPU render-load can't be split over multiple cores). -

No idea. It might be hardware dependent but given how many people with high-end kit are suffering from stuttering, at some level or other (it can be mitigated with a shed-load of tweaks that we shouldn't have to be doing) I think it's a good guess that the over-loaded single-core scenario is a good candidate. -

Panzerlang replied to Panzerlang's topic in Virtual Reality
Seems to me, 'all they need to do' is stop the code from maxing out a single core. If the load was spread evenly (as in 35% on ALL cores, instead of 35% on all the cores but the one getting hit for 100%) I think the stutter would be fixed. It's only my inexpert opinion but it does appear the MT coding is currently fubar. -

Wow! The very definition of 'picture perfect'! 36% package with one core getting a 100% flogging. -
It all worked fine after I put the missing line back into the LUA file.

Panzerlang replied to Panzerlang's topic in Virtual Reality
I did a performance comparison, fwiw. My personal takeaway is that ED need to look at why DCS is whaling on a single core, if that is actually what's going on. It certainly appears so and would explain the stutter.. -
CPU. Even with a 13900k and 4090, I'm CPU bound.
-
And yeah, from the end of the video, theoretically at least, it looks like Reflex would work wonders in VR. It brings frame-time well under the threshold of visual acuity.

I would really like to see this kind of analysis done exclusively for a flight sim, focusing on the CPU/GPU render. They make the entirely valid point about system latency vs human latency, where ten or twenty milliseconds of system lag is inconsequential compared to the average human's physical response time of 200 milliseconds. This is relevant to an FPS but not to a flight sim, where the latency that we're seeing is visual. Human visual acuity is in the range of 20 milliseconds and for us to see stutter and jerking means the render queue in DCS must be getting seriously choked. 13900k has 15 physical cores, yet we see "CPU Bound, Main Thread" in red. My layman's guess is DCS isn't spreading its load across a sufficient number of cores OR, if it is, there's some other chip/s that can't keep up (memory controller maybe). Next year, Intel saves itself by offering flight-sim only CPUs. Lol.

Panzerlang replied to Panzerlang's topic in Virtual Reality
Brand new install of the OS and DCS etc and I think DCS is running as well as it can, all the tweaks have accumulatively been very successful. -
Yeah, I have to admit the latest throttle was underwhelming. Seems all they did was re-jig the previous one into something with more metal and pretty colours.

It's not "fealty", it's a considered estimation that there's a point at which a company *should* realise that if it doesn't markedly change it will go under. Plus other calculations... a) First units are more likely to be of a better quality, if the company is playing that game (and it's been suggested Pimax did just that, as OG Crystals had none of the major issues the CLs did). b) Not waiting and thus avoiding short supply that appears later. c) Unit can be returned within two weeks for a full refund. An additional calculation now is will there be a 'run on the bank' that'll push Pimax under? The 'insanity' of announcing the Dream isn't so insane if Pimax is desperately trying to raise money on pre-orders. In that case it makes absolute sense but it would indicate just how close Pimax is to the edge. Unfortunately there's no ATM in view at which to check the queue. Lol.
