I too have questioned whether my replacement RMA 5k+ has a narrower or unchanged large FOV compared to normal, my original seamed more substantial. Without direct comparison I can not say for sure. How does the X compare from normal to large? Is there a noticeable change or is just simply slightly less rounded on the far edges?

Right but there should be a reported resolution in steam VR at 100% and PiTool 1.0 for each FOV with and without PP that should be the same between headsets of the same type. In other words, if you set your 8KX to Large FOV, PP off, Pitool 1.0, and steam to 100%, your reported resolution should be the same as my 8KX (once it arrives) if I set all of those settings identical to yours. There might be very small variations between PiTool versions, but they should all be roughly the same.
At PiTool 1.0, there should be basically 8 different possible resolutions 4 for each FOV (potato, small, normal, and large) and 4 more for those FOVs with PP on. I would expect a penalty and a greater resolution reported with PP on, but not such a drastic increase as what Industria is reporting. That is why I wanted confirmation from @SweViver of what resolutions we should expect to see being reported in SteamVR.

SteamVR does not know Large FOV over 2k. Therefore, it cannot handle it properly.
Valve has to take care of that
In addition, the resolution was about the start screen, not a game

Iâve asked about the 8KX resolution in SteamVR many times. Nobody answered. I just was told I will not need to use supersampling, so it is not a big deal. Yeah, right!
Some of those lines are not in the steamvr.vrsettings file - specifically that 2nd picture where you have âallowsupersamplefilteringâ : false (i keep it off anyway)
supersamplescal: 1 and resolution scale 1âŚ
Im using a 5k+ - is that why I dont see those lines?
Also, GpuSpeed at 2000 for all 10 lines - how does this affect the resolution? Or what is itâs overall effect by changing the values to 2000?

If they arenât there a default value will be used and if theyâre duplicated (same as default) theyâll be deleted on start-up I think.

Youâre responding to my question about the gpuSpeed?
I understand that part, but if we change it to 2000, what does that actually do?

AFAIK itâs only used by SteamVR home/dashboard?
It sets either graphical quality settings or just supersampling. Not sure.

only on potato to small you notice the rounded edges. the others are same vertically but just less wide.

Sweviver said that Steamvr does a short gpu performance test at startup and adopts its quality setting for the steamvr interface according to it. so if you set it to 2000 steamvr thinks that you have a beefy 2080ti and use a high resolution for rendering the interface. Again, i am just repeating what sweviver said. it makes sense. what else it is good for - i don´t know.

Understood. Thank you!

Do you see a noticeable difference from normal to large or is it so small that there is no use it putting it in large just a frame rate loss?

Also would like more of your thoughts. Thanks

I would say that there are only a very few situations or games where i would trade the loss of performance against this few more degrees of blurrness at the edges. Large almost makes no sense to me. especially when a game need pp on. lots of wasted processing power!
right now i use only the small fov. coming from index small is still considerably larger than what i experienced there. especially when pp on is needed. in games that work with pp off the extra fov when using normal is a nice extra, but that is of course individual preference to trade more grafic fidelity against fov. The good thing is: we have the choice!
EDIT: one more thing:
the more i play with setting with the 8kx, the more i want to trade fov with extra ingame quality settings. Because there is - for the first time - a treshold taken where i no longer put on the hmd and see immediately that its fake (mainly because of bluriness of everything in a little distance), but if the textures are great i have an uncanny valley feeling.
That´s the same reason why i prefered the 8k over my 5k+, despite the (regarding one pixel area) higher sde. The more of information made the picture more detailed at greater distance. I know that both had same native resolution. But the calculated pixels of the scaler tricked my brain to receive a more detailed picture - especially with higher steamvrss settings.

frankly spoken: Pimax software (complexity together with steamVR, eg) is sometimes a pain in the a**. But experience tells me that software is being improved and sooner or later complexity will be handled right.
Hardware wise the 8kX is simply the best high end headset right now. it is stunning.

You meant 2160 for vertical right? 3160 is scaring me!
I canât wait!!!..

nope, 3160. Thats why 50% SteamVRSS is around 2160 native vertical pixels and what i start with when optimizing.

The vertical pixels are needed for the distortion profile management, its quite a high number indeed but when I always say ânative 4Kâ in benchmarks, I always mean the resolution reported, which is indeed roughly 1000 pixels more on vertical side than native 4K.
This is also a reason why I strongly suggest a 2080 or 2080Ti for the 8KX, at least if you want to get a proper frame rate in most games, and dont want to compensate on the quality. The 8KX image looks indeed better with 3160 vertical pixels than 2160, even if (around) 2160 is still fine and sharp.
