3- at 70% of SS with the Crystal it’s like 170% of SS of my G2( I can run my G2 with SS-170% with smooth 90fps).
I run all sims except ACC at 100% render resolution / 1.0 SS / 4315x5100px: AMS2, AC, RF2 all with 2xMSAA and I have 90fps/hz locked. And I got DR2 running at 90% render resolution/SS + 4xMSAA, 90fps/hz locked too. All sims with ~high/ultra settings mostly and only one fixed foveated rendering ring of 71% 16th resolution(not visible during racing, but without this it won't be possible). This while I could run the G2 at max 3400x3400px + 4/8xMSAA(needed with G2, otherwise way to much shimmering with that low resolution) with much smaller fixed foveated rendering rings(30% first ring+~67% last ring). The Crystal is way more efficiënt with my system/the exact same configuration BUT you must use OpenComposite/PimaxXR/OpenXR toolkit, with SteamVR you cannot get it working with good performance. This with a oced 4090/12700k. And the difference is sharpness is HUGE compared to the G2 in the end, I would say ~around 60% sharper, while keeping the same 90fps/hz locked.
2- with motion system there is a noticeable blurriness on the distance subjects maybe caused from the headset wobbling?!.
No. This is probably because you run the Crystal at 70% SS. This is not enough for a clear image and especially not in the far distance.
Sounds like G2 can still hold its own to wait over these half assed new HMDs before something truly worthy upgrade come along, if ever.
Nah. The upgrade of the Crystal compared to the G2 is HUGE, even bigger than I expected/wanted it to be. This while I experienced the Aero as a downgrade compared to the G2 on most subjects and a upgrade on some.
1- IPD tried the setting from 58 to72 and I didn’t find any difference…. It’s like broken ?!
This is because the sweetspot of the Crystal is huge, it takes way more time to find your correct IPD. But once you do (so keep trying to find it ! ) the images is MUCH sharper than when you have it wrong and it's also way more comfortable to your eyes when you use/found your correct IPD. So you've not seen what the Crystal is capable of yet, because this makes a big difference in the whole experience. It costed me a serious amount of time to be honest so I understand your initial surprise/thought about this but it's not broken.
5- comfort .. the G2 Reverb with the Apache of is much much more comfortable than the Crystal.. I can play for 2 h without any problem… with the Crystal it’s the most uncomfortable headset I ever used .
I can use the G2 for a way shorter period of time than the Crystal. I can use the Crystal for ~5 hours in a row non stop with zero issues. With the G2, the heat was getting to much and the pressure on my forehead too. Same for the friends that also tried the Crystal here(also for an long period of time..). So I really think that this differs a lot from person to person. Hopefully you can find a mod to make it really comfortable.
there is a noticeable wobbling specially when there is a high speed sway/roll motion movements
The wobbling could be solved with the mod that I showed in this thread before: "LICHIFIT Head Cushion Quest 2 Strap". It also gives you the benefit that you don't need to tighten the knob on the back so much so that you don't have pressure on your forehead (I have ZERO pressure on my forehead/I got the knob really loose and the HMD never gets out of place/position during races, without this mod I also had minor wobbling with only a buttkicker installed).
Once you tweak your sims to run at 100% render resolution+2xmsaa + you find your correct IPD + (most important) you find a way to get it working comfortable(if it's still possible within your return time then try the "LICHIFIT Head Cushion Quest 2 Strap", it's only 10 euro or something), then you have a nice upgrade. If you're not able to find a way to use it in a comfortable way than you can better send it back indeed.
