Pimax 8K with VorpX

Hello, I am already ahead to find how to make games work with VorpX. I know that VorpX works with Pimax 4K for sure since I tried myself, you just have to select HTC Vive as HMD. That said I was trying already to set a custom resolution of 5120x1440 (the Pimax 8K 1440p format) to see how a game look but I was not able to create it on Nvidia control panel. I know what is the procedure since this is not the first time, but the screen just went black without signal and then revert back without any change. DSR is disabled. Any opinion? I think many of you expect to use VorpX with Pimax 8K…

  1. pimax 8k with be 3840Ă—2160 (4k) or 2560Ă—1440 (2k), 5120x1440 is definitely a wrong resolution.
  2. pimax 4k doesnt support 4k resolution natively because of hdmi bandwight limitation (as i know), so even if you force it with vorpx - it can crash the game or work with artefacts/color distortion (not always, but can happen, depending on a game youre running).

If you have really good graphic card you should try such titles as bioshok or fallout 4, this (and couple other games) support what they (vorpx) call “direct VR” which means you will experience best possible experience and vr support that vorpx can provide at all.
Personaly i would advise bioshock (you only need to find out which one, if not all of them), it’s very beautiful and might looks impressive with DSR.

As far I have understood Pimax 8K will be 2 x 3840Ă—2160 resulting on (3840+3840)x2160 i.e. 8Kx4K, hence if you want to run at 1440 it become 5120x1440. Which resolution would you set otherwise to feed 2 displays?

3840x2160 per eye becomes 7680x2160 resolution when combined.

Your not increasing horizontal likes as both eyes still only have 2160.

Vertical lines double as the idea of panoramic monitors.

Vertical 2160 , Horizontal 7680 ; (4K native in both panels)

It’s not really important how 8k will be, the fact is that current pimax 4k version supports only 2k because of hdmi that is not able to transmit higher resolution in 3d with required frequency.

So if you want to find out how the picture from a single eye will looks like all you can do is:
1.
a. set 2k and use lots of supersampling and antialiasing (depending on the game and your g. card) (overall quality is still limited to graphic card/hdmi bandwidth)
b. try to use vorpx and put the resolution to the max possible (overall quality is still limited to graphic card/hdmi bandwidth)
2. imagine a more clear and brighter picture with more colors (current version has lack of this things because of shutter glas).
3. imagine no ghosting
4. imagine doubled horizontal fov
5. imagine less sde (real pixel that you can see on display, not a software pixel)

conclusion: no matter how you raise the quality (&1 a. or b.) there will be not much difference because you’re always limited by hdmi cable that is not able to transmit so much information as you’re trying to force. Which is more important, current version has some cons described by &2;3;4;5 - and you can only imagine how good it could be without them:)

therefore i would not try to find out how pimax 8k will looks like, it has way to much changes, even if these chances are not completely removing all the issue but still decreasing them - overall immersion from 8k might be impressive and you shouldn’t really be able to see something similar in current 4k hmd.

Try this:

  • In Piplay Video Mode.
  • Activate nvidia DSR.
  • Check it to 4x.
  • In VORPX put Generic HMD.
  • In VORPX now give you the option to set resolution put: 5120x2880
  • In windows resolution (you are in extended mode) put the same resolution to Pimax.

Try any game in 5K resolution, it will give you an idea how Pimax 8K will perform.

I have found the problem, it is due to limited bandwidth of my GTX 980ti, I had just to lower the frequency to 30Hz and set 5120x1440 as custom resolution on Nvidia control panel.
