Would you look at your laptop to check if there are multiple graphics cards in it? If so, can you please disable the low end one to see if there is a performance gain? We know the Anniversary Update OS will the choose the best graphics card but the one used at startup. We know this because we have already been working with Microsoft on this. The compute of graphics has never done by DisplayLink as this is not a GPU. How do you measure your FPS? Do you have a sensor on the monitor, or is it an in-game counter looking at what the graphics card is handling?
The second aspect around general performance is on the engineering backlog to be worked on. There are a number of features which were available to us prior to this OS which have to be totally redeveloped with this new way of doing indirect displays.
The priority was to have the system work for the OS launch.
Kind regards,
Alban

The Intel GPU cannot be disabled, since the NVidia GPU is only a co-processor, but the NVidia GPU can be set as default. See

This changes nothing however.
But I was able to come to a new conclusion.
When both monitors are connected through USB the game reports a max of 17 FPS and is unplayable,
even on the laptop display.
With one monitor connected through USB and the other through HDMI the game reports 60FPS
when played on any of three displays. But still, the USB monitor is obviously not rendering 60FPS since the mouse cursor and the game feels obviously sluggish when compared to the HDMI and integrated monitor.
The FPS counter is an in-game one.
