I set it to “maxRecommendedResolution”: 6144,
The default vrsettings file seems to be written to every time steamVR is launched when pitool is running. This does not happen steamVR is launched on its own (without pi tool running)

Hmmm… May need to try making it read only & see if it works.

Did you tried to revert to 4096 to see if the resolution sinks ?
I saw this setting some time ago, but deduce that “MaxRecomendedResolution” was to stop SteamVR to auto move the slider to resolutions that the Vive/VivePro display can´t render and waste GPU resources (100% diminished returns).
But i will try to test it tonight.
ALSO
I managed to run Chronos. But i had to run it thru SteamVR and because of that it needs PP on, so the image loses some clarity. But work anyways !
I literally used the revive injector that can, somehow, bypass the “Entitlement check”.

Thanks @tristanc. This is great!
I just run the test and can confirm the value works as expected. I set it to 8192 and then set PiTool to 2.0 and HMD to “Large FOV” thus making the driver to advertise
HMD driver recommended: 8535x5267 90.0Hz HiddenArea(3.49%) = 7809 MP/sec
and then verified that the OpenVR has capped it according to the new settings and advertised to the application 8192x5055.
If anyone does not know (it has already been reported here), the settings values are also accessible from the “dev console” which is running at http://127.0.0.1:8998/console/index.html.
You can read or set the values from there by using settings command, list gives the other commands. The disadvantage is that the SteamVR has to be running. The advantage is that you get an immediate acknowledgment that the value has been (correctly) updated, you do not need to search the right file, and it looks more tidy.

works for me too, heres how i tested it with iracing:
large fov+parallel projections and render scale in iracing set to 50%.
steam at 5011x2373 looked reaaaaaaaaaaaaaly bad like 360p or something 
changed steamvr slider to maxvalue of 15538x7359 and it looked exactly the same
then i changed the maxresolution in the webconsole from 4096 to 40000 and it really changed after that

How to use it with the “dev console” added to the first entry, thanks.

does this “stick” if you close steamVR and launch again or do you need to enter maxresolution in the webconsole again?

Is this for vertical or horizontal resolution?

I tried this hack myself. Now with Pitool still set at 1.0 my frames dropped from 90 to 25 in most apps. But god it’s looks sharp! So reducing Steam down to 30% brought the FPS back up to 90 and it still looks fantastic.

What did you set maxresolution to?
Is Pimax going to explain us one day what is the different between Pitool pixel percent and SteamVR SS?

The 8192 recommended.
Other things I tried was the Nvidia Funhouse now works.
The combination of Nvidia driver, new Pitool and upping the maxrender resolution has this headset now looking eye popping! In a good way lol

As an aside: In the “power” section of that default settings file, you will find “autoLaunchSteamVROnButtonPress”, which you can set to false, if you are having issues with SteamVR launching prematurely. (Used to be selectable on the control panel setting, but I have not managed to find it there recently.)

Is it me or have Valve changed the menu system for SteamVR? All tiles now.
Yes. They also changed the SS menu.
Now there´s only one option and slider to gauge the SS, which don´t show the % anymore
