  • So many suggestions for putting your phone near the shower but outside of it… phones are waterproof now. I just bring my phone with me in the shower now, and use my notes app to write down anything I don’t want to forget. I was already using it for a shower checklist, since I find it pretty hard to function in the shower. Also doubles as a way to consistently clean my phone, which is a nice plus, I likely wouldn’t remember to specifically clean it very often otherwise.

    If your phone has a charge port plug, make sure to keep that in during the shower, if it doesn’t have a plug, keep the port oriented down, or you may have to wait a couple hours to be able to charge after. I’ve had my last couple phones in the shower hundreds of times now over the past 10 years, only had it happen twice where the charge port got too wet and had to dry before I could charge it, and neither time was when the battery was low enough for it to matter.










  • So, a 55-inch TV, which is pretty much the smallest 4k TV you could get when they were new, has benefits over 1080p at a distance of 7.5 feet… how far away do people watch their TVs from? Am I weird?

    And at the size of computer monitors, for the distance they are from your face, they would always have full benefit on this chart. And even working into 8k a decent amount.

    And that’s only for people with typical vision, for people with above-average acuity, the benefits would start further away.

    But yeah, for VR for sure, since having an 8k screen there would directly determine how far away a 4k flat screen can be properly re-created. If your headset is only 4k, a 4k flat screen in VR is only worth it when it takes up most of your field of view. That’s how I have mine set up, but I would imagine most people would prefer it to be half the size or twice the distance away, or a combination.

    So 8k screens in VR will be very relevant for augmented reality, since performance costs there are pretty low anyway. And still convey benefits if you are running actual VR games at half the physical panel resolution due to performance demand being too high otherwise. You get some relatively free upscaling then. Won’t look as good as native 8k, but benefits a bit anyway.

    There is also fixed and dynamic foveated rendering to think about, with an 8k screen, even running only 10% of it at that resolution and 20% at 4k, 30% at 1080p, and the remaining 40% at 540p, even with the overhead of so many foveation steps, you’ll get a notable reduction in performance cost. Fixed foveated would likely need to lean higher towards bigger percentages of higher res, but has the performance advantage of not having to move around at all from frame to frame. Can benefit from more pre-planning and optimization.








  • Overall is that even a deal over a used headset? Even a fully featured non-stripped down one? Like given what features his headset does have, it’s comparable to some pretty old headsets… and it likely does even those bare minimum features more poorly than an older used headset would. Not to mention comfort.

    Like a 10 year old Rift CV1 has almost as much resolution at 90hz/fps instead of 60. And while it’s lenses would be relatively terrible now, they were pretty much the best option of their day, and likely still better than whatever this dude sourced. Not to mention their motion to photon was around 12 ms. The absolute best result this guy can hope for is 16.6ms, and that’s only if everything else in the pipeline is faster than the screens refresh rate… maybe it is… but I wouldn’t bet on it personally.

    I’m sure it was a fun project though.
