HP Reverb G2 vs. Pimax 8KX - My Full Review and Comparison

  1. I think the lenses improve the overall perceived resolution. It’s easy to focus on things. It feels as clean as when you put on glasses for the first time. I can tell the lenses are very well designed for maximum clarity. I now sort of understand what Sebastian meant when he said the 8KX feels like wearing someone elses glasses.
  2. SteamVR resolution was set to 122%
  3. I also tested Pavlov but I chose to focus on Alyx because it was easier to see the biggest difference in that game. This time I went into the same scene as before in Alyx and switched between headsets quickly to make sure I could catch it. Then I had realized I underestimated the sharpness of the G2 and then realized 20 to 30% is more like the actual difference. For 8KX test I included the 16384 maxRecommendedResolution line and PP off with the Alyx command settings. For G2, I removed that line and the command line options.

But 122% in steamvr can give us different resolution per eye for individual hmd and for pimax additional Pitool settings like fov ,render quality is changing steamvr res.
Can you please set 3000 or 3200 pixels vertically for both headsets in steam vr app and tell us how big is difference in perceived resolution.
I can imagine that reverb lenses should give better clarity ( like modded Vive with GearVR lenses) but not really resolution /PPD or meybe G2 lenses is concentrating munch more pixels in center and less at sides that’s why is a bit blurry at edges ?

BT was a factor back when it was separated from the hmd. Starting from the OD+ BT is inbuilt and free of any issues.

I have tested all tracking methods (still having LH1 + wands LH2+ knuckles and OD+ wmr tracking) and I really can say that I do not miss LH2 tracking in almost any case. I even can use both (mixed) with the vive dongles but I hardly use that.

Heh… Love the contrast between simulation gamers here saying how important large FOV is to them, specifically because they are sim gamers, and all the times I have had other simulation gamers vehemently telling me they, as simulator gamers, have zero interest in a large FOV, or even a decent area of sharp focus, casually waving away my argument about the optical flow to the sides being important to convey an impression of speed. :stuck_out_tongue:
I suppose most of those earlier have specifically been players of drive-fast-car games, who keep their gaze glued to the vanishing point. :7

(EDIT: Love being able to see the planet I just took off from receding behind me, without having to surgically turn myself into an owl, myself. :7)

Sounds like the G2 is growing on u. :0)

Can you imagine after buying a 8kx, 3080 rtx, then tell your wife you need 1 more vr headset :rofl::rofl::rofl:

I was going with G2 or 6800xt gpu…(her) but you already have vr headset?? (Me) your right babe…6800xt it is!:kissing_heart:

You pretty much tested most aspects of the g2 we most interested in against 8kx.

Tracking wise how did you feel about that after some more time with the g2, do you feel its good enough, as in to replace it as your main controller.

I only use the Index controllers with it. But I can try going back to WMR controllers for a while and report back. Will probably do a tracking video sometime.

Good job detailing the process. One thing is to link the FoV test in the description also. That way people can get do a test first and if you’re someone like mrtv that’s closer to ideal you might want to leave it as is.

Having said that maybe @mixedrealityTV can do a similar mod on his and see if his FoV goes up as well.

There are two approaches to comparing the image quality of two different headsets.

  1. Set the same render target resolution on both (this should guarantee more or less same framerate)
  2. Set the render target resolution on each to the maximum (applicable).

The first one is easier to do, but it does not really tell what is the headset potential, or, FPS-resolution trade-off. It also requires that you render the same resolution over the same FOV.

The second is based on the assumption that you want to max the resolution to the point where its increase does not produce any improvement anymore. It could by maxed by either the PPD limit (which is different for each HMD), or by the optics (how well the lens can focus on the display over the whole FOV).

Ideally you would like to test both, first to give you the comparison at the acceptable framerate, second for knowing what you can achieve (if you have a GPU powerful enough).

Other than FOV the G2 blows the 8K X away in just about every aspect… colors, clarity, contrast, brightness, sound quality (my dmas still hasn’t come). Honestly, the clarity of the 8K X is still very good, but it’s about equivalent to the Quest 2. The Quest 2 has actually become my headset of choice for many games even though it’s worse clarity than the G2 because of one giant benefit: wireless. The wireless through Virtual Desktop and a good router is surprisingly good.

That’s a good thing, not a bad thing :slight_smile: The Quest 2 is the clearest headset I’ve tried besides the Reverbs… yes, more so than the Index if you optimize the link settings.

I am waiting for one, should have it this week, will see how is the clarity compared to my 8k+.
But didnt like the Quest 1, like not at all, so this is going be interesting.
