Hi all

I am in the situation like many G2 users and in the next time i need to change the VR of obvious reasons (thanks dumb MS).

Quest is no option for me and as far i see here in the thread the Pimax Crystal Light seem to be a good upgrade.
But one thing i dont understand.... Aapje mentioned something about "You'll gain eye tracking, but you'll have a much less comfortable headset, and have to deal with charging the battery a lot."
What does this mean? Crystal Light is a PCVR so its powered via a cable right? Can someone explain please?
 

Crystal Super is i think too much or too demandable due to the bigger resolution?
Would say my system is quite good but is the Crystal Super really worth it?
Does it work good with DCS?
I am not sure about the differences about Crystal Super (Ultrawide?) and Crystal Light beside the resolution topic.

And the Pimax devices run on its own software, right?

Crystal. Crystal Light. Crystal Super.

All are different headsets. Don't confuse them.

That is only about the original Crystal. Pimax has a bad habit of copying other companies, even when it doesn't make sense.

For the original Crystal, they tried to copy the Quest, creating a headset that can be used standalone, with a mobile chip and battery inside. However, no one buys a Pimax for standalone, so they just made a headset that is more heavy than needed and requires charging (even when using it wired).

For the Crystal Light and Crystal Super, they fixed this, by getting rid of the mobile chip and battery.

The Super partially compensates for that due to the eye tracking, which allows proper foveated rendering (using a lower resolution for the area in your peripheral vision).

With a 4090, you can definitely benefit from the Super's extra resolution, especially since there is also the option to use DLSS 4.

Thank you for the clarification.
Hm, so now maybe one last question because i see 3 different options on the Super.
50PPD, 57PPD and Ultrawide.


So Ultrawide is basically clear that this thing has wider fov but to be honest dont really know which one is then the best to choose?
As far as i know the G2 has something around 88 fov.
Is then the 140 fov not too much and has the fisheye effect?

And the the other both versions 50PPD and 57PPD dont really know what this means in reality.
Is there a price difference in the three versions coz the Pimax hompage shows me (in the EU) a actual price of 1588 Euro.
So which one is the version to choose from? Its confusing.

I play lot of DCS and Simracing. 
Maybe from time to time Alyx and Pavlov.

50 PPD is lower clarity and more FOV.

57 PPD is the opposite.

Ultrawide is more FOV, high clarity, but less depth perception due to a smaller binocular overlap: https://www.roadtovr.com/understanding-binocular-overlap-and-why-its-important-for-vr-headsets/

The difficulty with all of these things is that what matters most to you is very personal. In fact, everyone has a different FOV, PPD and binocular overlap depending on their face shape.

So to a large extent, it is a gamble. I would probably pick the ultrawide if I were to get one:

Thank you for the detailed explanation.
Due to the fact that ive didnt had any problem with the fov of the G2 so i think the 57PPD version sould be the best option.

It has more fov and the clarity advantage so this seems to be the best compromise.
