Pimax Crystal Super Ultra Wide - Only getting 120ish FOV

General discussion
1

I’m only getting around 120 degree HFOV with the Pimax Crystal Super Ultra Wide.
And that is with the thinnest facemask and the headset super tight .
Anyone else? I have tested in several different test programs (TestHMD & WimFOV)
I am a long time Pimax Crystal OG User.

@PimaxQuorra can we have the new Pimax crystal super ultra wide profile to test ?

For me I just had to lower the IPD while the autmatic ipd was 71.7 with 68.5 I got HFOV132 to VFOV112 instead of HVOF116 to VFOV90, but i really getting into Performance issues in VRChat, other then when using the 5k Super or the Vision 8k plus, I had to down scale it to 5k to be able to use the Super in VRChat, i didn´t tryed other games yet with the original Resolution, also i can´t lower the Image Resolution the Middle, while its otherwise not sharp enough any more

rest was set up like on the 5k and 8k

My Issue is that if I don´t downscale my 16GB VRAM gets filled fully and I have an 5080 OC

Or do I need a 90series to be able to use the potential of this VR XD

I have similar numbers. My personal measured IPD is 67.0 mm. I am not really sure of what software mods I need to do to get a bigger FOV out of the headset…

Changing your IPD away from your real IPD does physically increase FOV, but most of that extra FOV is optically invalid because the distortion correction was calculated for the proper eye position, so the extra view is stretched, warped, and not truly usable.

I doubt in that. I have the same Gfx card and in most scenarios reaching 12GB video ram usage.

I"m playing mostly racing sims like iRacing , LMU, Dirt Rally 2, ACC and also flight sims like DCS and Il2

For instance : for LMU , my setup is 100% res, ultra textures, rest medium and is very stable, but I’m using pimax oenxXR. 0.44 and toolkit 1.38 with enabled CAS ,cro2fov and fixed fovated rendering . Mbuchia apps are working 25% faster than pimax client adequate features

Maybe you should clarify what you meant by “5k”. Is that 5k per eye or total?

5k total is quite a low resolution, and 5k per eye is a pretty good setup. Huge difference here.

oh yes i mean by All, sorry

Also a friend of mine were able to help me, after activation of Dynamic Foveated Rendering on Custom with HGAR (40%) / VGAR (50%) / GAR (150%) / PAR (70%), Pimax Central Priority Rendering on Quality, Upscaling NIS on Balanced, Image Quality on Customize and in Steam the setting 4K per eye, to achieve only 12GB Usage in VRChat

Ok So apparently, my last measurement was incorrect, today I visit at an optician and got my IPD.

The Super always Set my IPD up to 70.4mm but it was wrong, since my IPD was meassured the official way today at an optician and got 66mm measured.

So with an IPD from 66mm set in Pimax Play, I only get 120 HFOV and 108 VFOV
