72fps, ATW/ASW in tandem

[eneo1]

Hi, first of all, great software you have here! Working stellar with my PC and OGO.

I was wondering if you are planning to introduce 72fps mode for Oculus GO?

Also, what about Asynchronus Space Warp together with your implementation of ATW? My thinking is that with ASW, you only have to stream 50% of the frames to the HMD, reducing latency and requirements even further. Maybe as a toggle in ALVR server.

HELLO.
Totally in agreement with the previous comment, the use of the 72 fps in GO can make the difference, is the implementation of this system possible?

If you look in the default.vrsettings file in the driver folder for alvr, there is a setting of 60hz, maybe u can try change it to 72 and see what happens?
Of course it may mot work if u need to make changes to the client also.

"displayFrequency" : 60,

"displayFrequency" is only historical config. Which is not used now.
We need to fix all hard coded value (16ms or 60fps) to configurable.

Is ASW supported on Oculus Mobile SDK (Gear VR/Oculus Go)?

Yeah you may be right, ASW doesn't seem to be available in mobile SDK.

This is what I've found on 72fps mode:

vrapi_SetDisplayRefreshRate( app->GetOvrMobile(), 72.0f );

Its possyble 72FPS i any mode of configuration, it could be the most big difference with OCULUS GO¿?¿?
something like this¿?
vrapi_SetDisplayRefreshRate( app->GetOvrMobile(), 72.0f );

Thank you for the information.
I have release v1.9 which support 72Hz mode!
I can not test because I don't have Go, so please check yourself.

Thank you for report!
