V2.0.1.7.3 eat CPU very much, about 30% of CPU

V2.0.1.7.3 eat CPU very much, about 30% of CPU, and the display laggy. V1.0.xx all have no CPU issue, but V1 will keep connect/disconnect HDMI many times when windows turn off the screen, and this is which don't happen in V2.

could you fix the v2 CPU issue?

yes @MindShow ,

I also experience the same issue with @chris840903, both in 2.0.1.7.5 and 2.0.1.7.3.

Both is taking 40-50% of my CPU, and I am using Ryzen 5 3600x.

do you and the team have plan to improve the performance? 40-50% is quite big for just this 😭

It is taking my 36% CPU in my Ryzen 4600H, please fix this?

Also, in Windows 11, the mouse cursors are not appearing in the external monitors. Can you fix this please?

Also, is it possible to open source this please so that we can look in and fix things and customize as necessary? Thanks

Do you have a fix or a plan to fix this issue? Is this driver the only option to use or has any user found a replacement for this driver?

Downloaded newest version from here http://www.ultrasemi.com/usbdisplay/ but it still uses about 30-40% of CPU
