[PLUTON]

in Open XR Toolkit what exactly is the Turbo Mode (experimental) setting for?

 

Thank you for the answer

Thank you mbuchia for your answer.
I tried to fly with Turbo Mode activated but it's a disaster, the game starts to stutter a lot and becomes unplayable and when I deactivate it everything becomes fluid again.
once again thank you for your help.
Good flight to you

Probably it is just because with turbo mode motion smoothing doesn't work

[PLUTON]

in vr flight I have never used motion smoothing.

I redid my settings and I tried again with the turbo mode and surprise it works pretty well for the moment, with the 2.8 I had lost about 15 fps (from 60fps to 45 fps) now with the turbo mode I'm back to 60 fps with msaa x2 in addition.
Hope it will last that way.

Turbo mode will never improve your appGPU frametime.

To the best of my understanding, when below refresh rate, WMR will force the the FPS to a lower value (relative to appGPU) in certain circumstances.  For example you might be getting 17ms appGPU which equates to 58fps, yet the FPS counter could be reading 45fps (22ms appGPU).  Sometimes it will manifest, sometimes it won't.

I believe you Mr Edmuss
  but as I am not a very big computer expert I only say what I see on my
helmet or screen (the figures) so could you explain to me why when I activate Turbo mode my fps is at 60/61 Fps and when I deactivate it my Fps drops between 40/45 Fps? And that every time I do it?
however that it displays 60/61 or 40/45 Fps it is still as fluid.
At the level of the image nothing changes, what changes is just the different Fps. Weird, isn't it?
In the meantime thank you for the answer Mr edmuss

I still hope for your comments because I like to learn from those who know it, thank you in advance

There is a caveat in the details of turbo mode from mbucchia page which may explain what you see and feel:

Any statistics or performance measuring tool might now present incorrect data

[PLUTON]

Ha ok I didn't understand that.
Anyway, thank you for this short and clear explanation.
