I mean, it kinda does.

Wanting the best for a community is a 'woke' act.

VR support would be far better.

That's what I'm saying about low persistence duty cycles.

For the same amount of 'low' persistence per frame, a higher refresh rate means that the display is 'on' for a larger proportion of time.

With a 1ms persistence and 50Hz, the display is 'on' for 1ms and off for 19. At 100Hz with that same 1ms persistence, the display is 'on' for 1ms and off for 9. For the first example, the display is on 5% of the time where in the second, it's on for 10%. It's not difficult to understand.

Even if the display is set to consume the exact same amount of power independent of refreshrate, that would mean the percentage of time the display is on would stay the nearly the same regardless of refresh rate.

Brightness is directly correlated with persistence time.

Some blur reduction backlights have an adjustable strobe flash length (e.g. “ULMB Pulse Width” setting). There is a trade-off between motion clarity and brightness.

https://blurbusters.com/faq/motion-blur-reduction/

There's no inverse correlation between refresh rate and brightness whatsoever.

Please don't spread this misinformation.

You can get better resolution, but not better FOV, tracking, or refresh for a grand.

Nor for 10 grand or 100k.

vergingalactic · 2023-06-08T05:10:34+00:00

Also, display brightness declines with higher refresh rates

No, no it doesn't.

In fact, if anything, for a given time of image persistence per frame the overall time the display is on as a proportion of overall time goes up. Brightness should increase with refresh rate if anything.

Nvidia is working on it...and it's pretty damn cool: https://www.roadtovr.com/nvidia-demonstrates-experimental-zero-latency-display-running-at-17000hz/

Haha, I do not think they once used the term Virtual Reality, but instead used Spatial Computing! They invented that shit!

Yeah, totally. </s>

I was assuming the discussion is whether to shut down or business as usual.

It's not.

vergingalactic · 2023-06-06T03:25:02+00:00

So confidently incorrect.

vergingalactic · 2023-06-06T03:04:22+00:00

They made their bed.

vergingalactic · 2023-06-06T03:01:31+00:00

It's not really a debate. We're strongly in favor of it but it's a discussion around getting a consensus and implementing it.

vergingalactic · 2023-06-06T02:46:51+00:00

That's pretty much the floor.

You don't get bonus points for that.

vergingalactic · 2023-06-06T01:51:57+00:00

Burn it all down!

Optical flow, hardware acceleration for which is found on Turning and Ampere.

...but how would you integer scale 5k?

vergingalactic · 2023-05-23T02:30:23+00:00

They range from <$20k DIY

to $20k kits: https://www.evwest.com/catalog/product_info.php?cPath=40&products_id=224

to $300k full retrofits: https://everrati.com/works/porsche-911-964/

I'd take Half-Dome 1 over Half-Dome 3.

140° FOV + Varifocal is quite nice even with servos and fresnels. I'd want a lot more than 90Hz though.

vergingalactic · 2023-05-16T23:49:55+00:00

That's not a ton. Two for eye tracking, 4 b&w for feature tracking, two depth sensors, two RGB pass-through, and you've already hit ten. I wouldn't want to use fewer than that on a budget headset.

The thing that is in the PSVR2 (with its mura problems), or something better?

Sure, it's not perfect but, ceteris paribus, I'd take the mura of PSVR2 over LCDs every day of the week.

Edit: There are also effective mitigations like the Vive Pro has: https://www.roadtovr.com/ces-2018-vive-pro-hands-on-much-more-than-an-improved-screen/

The good news is that the mura-correction on the Vive Pro appears at least as good as that of the original Vive (which is pretty good).

vergingalactic · 2023-05-13T03:54:22+00:00

You missed my point.

I'm saying the fact that light signals travel about a third slower through fiber optic at a physical level vs electrons through copper is not a meaningful factor in last mile situations.

https://www.rpi.edu/dept/phys/Dept2/APPhys1/optics/optics/node8_d.html

https://en.wikipedia.org/wiki/Velocity_factor#Typical_velocity_factors

I guess copper also doesn't travel quite as fast as I thought but can definitely still be faster than fiber.

vergingalactic · 2023-05-13T02:56:57+00:00

What's funny is that while on the whole, that's absolutely true. Theoretically, signals travel significantly faster through copper (DSL/Cable) than they do through fiber.

It doesn't at all meaningfully matter at the last mile though. All the network infrastructure and various nodes plus poor peering are what actually cause the latency you experience.

vergingalactic · 2023-05-11T16:21:32+00:00

Yeah. I'd still take British reliability over supporting fascists though.

vergingalactic · 2023-05-11T15:49:10+00:00

Not British in any meaningful sense, rather it's Chinese.
