      Thank you. Objectivity is hard to maintain, especially if you're excited about the technology offering. However, I feel as though it's an obligation to present the facts as they're perceived, at least by myself. Anything else would seem somewhat disingenuous! I'm not here for clicks or subs, even though it's useful to know if I'm offering useful content - I'm just excited about the technology. It's a beautiful thing to be able to fly with friends and not worry about racking up tens of thousands of dollars in deferred maintenance as a result..

    Hi Tally, nice to hear positive feedback about new lenses.
    About 72Hz, I want to share some experience using it my 8kx. It is excellent for simms, if you are used to it. But, if you usually use 90 or more Hz, then you will not like it. It makes eyes tired, or some may feel slightly discomfort from lower Hz number.
    Fortunately there is a better solution: set your HMD on 120Hz, and then lock your fps (in OpenXRToolkit) to half of it; 60Hz. What is difference? Your HMD will do 120 pictures per second, and that feels much better for your eyes for longer playing. But with locking game to 60 fps, your PC will change every second picture, and will have enough time for all calculations. This method is totally different from just setting 60Hz, which (in my opinion) feels like somebody punching me in face.
    That exactly ratio 2:1 (120Hz:60Hz) has some magic in it to trick eyes and mind, and feels smoother than other solutions higher then 60Hz. I highly recommend it to try.
    I do not have 120Hz on my 8kx, so I use similar trick with 90Hz HMD + locking fps to 45. This looks good enough for jets in DCS (without much turning), but not for other games. I wish I had 120/60 combo, but it does not work on my system...

    • @tallymouse
      @tallymouse  Рік тому +2

      Yes. I have the 8kx too! I found the half-rate lock to 45Hz while running at 90Hz to be a very good option. With the half-rate lock on the Crystal, 36Hz, 45Hz, 60Hz, 72Hz, 90Hz, and 120Hz have all become options..

    Really well done, as a lens geek I apricate the info about the shape of the lenses. It should reduce CA, I actually though that the wider FOV lenses would have had higher degree of CA. As they needed to most likely reduce the focal length a bit.
    I still think that the interchabagle lens system was genius, as it leaves so much room for further development and makes the headset quite flexible.

    • @tallymouse
      @tallymouse  Рік тому

      From the shape of the lens, it appears that they've attempted to maintain 35ppd in the center of the lens, tailoring off to [probably] 32ppd at the edges - think of it as a redistribution of pixels. I didn't readily notice any difference in clarity between the standard lenses and the BIG FOV lenses. These are still under-development, so it wouldn't surprise me if another prototype comes out for testing that has a larger HFOV. I believe they really are trying to replace the feeling of the 8kx in normal FOV mode.

      I guess this was the point of my video - different people with different face/ocular-cavity shapes and geometries will always end up with significantly different values - it's not a Pimax thing, it's a lens thing!
      The important value is the difference or the increase, compared to the standard lenses, that the BIG FOV lenses can offer you - and that appears to be anywhere between 8 and 12degrees. An average of 10degrees when flying or driving can make a huge difference to your immersion and situational awareness.

    • @tallymouse
      @tallymouse  Рік тому +1

      If you have a very high-end system, you'll probably still run 90Hz or 120Hz. I'm quite happy running mine at 90Hz. I tan at 120Hz for a few weeks, and the only real benefit I found was when my fps indicator hit 120Hz while above the clouds, apart from that I couldn't perceive a visual benefit over 90Hz.

    Very nice work on this video. I am currently trying to decide what to get to replace my G2 since it is having issues. I have seen reviews from others complaining about barrel distortion and of course the CA issues. What say you to these issues? I was hoping to be able to wait to get the Somnium headset but no one has a clue when those will ship or how they will be really be. Nothing else on the horizon that is promising in the sub $3k price point. I do have a good PC I built with a 13900k and 4090 so I should be able to get good performance with a new headset. Pimax does concern me with their class leading terrible customer service and horrible return policy combined with the build quality issues but the image quality is the only thing that keeps this headset alive in the market really from what I am seeing.

    • @tallymouse
      @tallymouse  Рік тому +1

      Remember that the Somnium VR-1's specs are identical to the Crystals, yet being manufactured by a company that's never produced, shipped, and sustained/supported VR headsets before - so even when it does come out, it's not going to be a rose-garden!
      I, personally, haven't had any issues with barrel distortion or CA. If you need to wear spectacles, you're always going to notice more CA than somebody without as that's just the nature of stacking multiple lenses together in an optical system.
      I was part of the beta testing group, and a few members of the group were going out on YT and reddit publicly complaining about private pre-public-release software (i.e. not understanding what beta testing is about). Of the people I can verify actually own a Crystal, the vast majority are delighted (the silent majority) with it, and wouldn't go back to anything else. Many of them also own all other headsets, such as the Aero, the G2, Quest Pro etc. With respect to support, when I got my first Pimax headset (8k plus), support were great - when I purchased a 8kx from a third party, and it was faulty, support replaced it and sent me a new one directly from China, very promptly... the wheels came off a little at the beginning to middle of this year with support, as they were simply just swamped with support tickets, mostly due to beta testing running concurrently with initial Crystal shipments.. However, things are getting much better as the Pimax leadership team have been really proactive in moving around trying to coordinate where they could, and pull priority tickets out of the system and getting them moving again.
