FYI there is a new release of virtual desktop which offers to move the workload of frame interpolation from the PC to the headset for a performance boost which is always welcome in MSFS.
I haven’t been able to test it yet but there are more details here:
The dev confirmed that for now it will only lock to 50% refresh rate so maybe it will currently only be helpful for those who can reach 30 or 36fps… Hopefully he is able to lock it lower in future updates as apparently it is a big improvement on regular ASW
It’s also pretty wobbly in FS2020. But not as bad as with ASW. And you’re right, if the framerate drops below 30, it’s not useful. So, I hope also that this well be improved in the future. But it’s a good step forward.
