I’m always up to try a new setting. I am one of the ones currently running it at 90hz with 1.5x and the 960 encode rate in ODT. MSFS looks great with ultra settings, but the clouds have some obvious pixelation, which I guess is the compression?
Can you share the MSFS settings that you are using in conjunction with the 400 encode and 72Hz please? We have a similar build.
I have ASW disabled. I fly GA around southern England mostly and can hit 72 FPS in most areas outside of major cities and London area so it’s sublimely smooth.
The only stutters I get are occasional data loading when flying into a new area.
But being able to look down at the ground and see houses and trees move underneath buttery smooth is the biggest difference between 3090 and 4090. I can forget I’m playing a game at times.
If it runs for you at 960 without audio stutters then I’d keep it there, for me the sound cuts out every 15 seconds or so at that encode rate.
My settings are 5408 x 2736 resolution in Oculus app, 72 Hz. 2896 x 2618 per eye in Steam VR and in MSFS. I use TAA over DLSS as I find DLSS quite blurry.
In my MSFS user config file I have disabled all VR post processing except sharpening which is enabled. Everything else is set to 0.
In the ODT I have encode at 400, the resolution width is what that guy the forum link you put up recommended. It works well.
In sim I disable Anisotropic Filtering and instead set that manually at 16 X in my NVidia control panel. I also set LOD bias to Clamp in the Nvidia panel.
For good performance I find the most demanding settings are Terrain LOD and traffic. I set my Terrain LOD to 170. I prefer 200 as it eliminates pop in but I lose too much performance in major areas then.
Traffic is a real performance killer, I set traffic variety to medium, GA and Airliner traffic to 30, cars, global shipping to 50.
I turn off airport ground traffic, set worker traffic to about 30 and plane ground traffic to about 30.
I find traffic and Terrain LOD impact my performance more than anything else.
Thanks for the detailed response! No audio issues here, luckily, but I will work in some of those other tips (especially the config file pp stuff) 
That sounds amazing! It’s all about that buttery smooth scenery for me too. What Res and up scaling are you running to get 72fps? I’ve noticed a weird thing with MSFS where increasing DLSS level and/or resolution actually increases CPU load and can (paradoxically) decrease fps via CPU limit compared to a lower resolution.
EDIT: nvm, I see you already provided settings in the post above.
So you are getting 72fps with terrain LOD 170?? That’s crazy. On the G2, 7800x3D, 4090, I need to go below 100 to hit 72fps,and that’s using DLSS performance… wonder whether that is down to WMR VS Oculus
A man from Planet Pimax
Pimax released a video today announcing that the first batch of pre-orders are now being sent out. Don’t get your hopes up just yet, as they only had 50 to go (I still checked my email though, lol).
New in depth video preview from Disco: The Hardest VR Review I've Ever Done... Pimax Crystal - YouTube
Interesting to know manufacturers are pushing VR headsets to new limits, but with current hardware and technology they seem to overkilling.
I am fine with my current HP G2 for the resolution and my system definately can’t run something more powerful.
However, if more users get in the VR realm probably we will get more attention so for this I am more than happy.
Will some of the most important issues in VR be solved in MSFS when they get released 
?
Some discussion about it
how come some people have received the crystal. i can only do the 30$ pre order
@shameelx1249 Pre-orders have been available for a long time, since late last year, so they have a lot of them to get through, and they’ve only just started mass production with the first 50 units. I assume they will ship them in order of pre-order date. There are also reviewer and beta tester headsets that were sent prior to that.
I expect it will take several months for them to fill all the pre-orders they already have.
but when do we pay the 1500? i pre ordered like a month ago.
I think they email you to complete the order when your pre-order number is almost up.
makes sense, thanks for the info
Thankfully (or terrifyingly) it seems I was in the first 50, got my order link last week.
Decided to go ahead and take the plunge after seeing various positive impressions… little bit nervous as it’s a first pimax for me but looking forward to it all the same!
Nice one! Be sure to report back! I’m especially interested whether 60fps at 120hz feels smooth, that would be a game changer (similar to 45fps at 90hz in the G2, no MR).
Hey, congrats. Hope you like it, and I also would love to hear your impressions.
My pre-order dates from late January this year, so I will be a fair way down the list.
Just a quick heads-up guys. Looks like things started to move the right direction, just received the invite email and completed the final payment. So keep an eye on you email if you pre-ordered early and good luck to you all. Very excited and keen to try the headset on my system. 
Cool, may I ask how much you ended up paying for the Crystal and for shipping?
