To make sure that the perceived slowness really depends on the graphics, please do the following for a test: Set the Scale Factor to 100%, knowing that it gets difficult to read, and use a small window like 1920x1080 or even 1600x900 or even smaller. Do the problems still occur then?
I've already done this test without success: the problem occurs with whatever resolution.

Anyway, using VB with 1920x1080 on a 5120x2880 screen is not a valid use case for me.

Thanks for your concern anyway.

@J Chin

Thanks for sharing experience.

I think I already tried this combination unsuccessfully, however I've done so many trial and errors over the past 6 months that I can give it another try and report back.

Today, I found the following settings that seems to improve my virtual Win 10.
1. Virtualscreen 1 @ 100%
2. Inside the virtual Windows: Display Settings > Scale and Layout > 200%

I'm still testing it out, but for now but it seems to be improved a lot judging from my mouse cursor movement.
No chance for me, exact same behavior as with
1. Virtualscreen 1 @ 200%
2. Inside the virtual Windows: Display Settings > Scale and Layout > 100%

Thanks for sharing anyway.

Hi FoxInCloud,

Yes I can also confirm it's the same. Doesn't seem to work, unfortunately. :-(

I've also tried running Windows 11 but it appears to be slow like Windows 10 as well.

However, both Windows 10 and 11 runs smoothly if I output my display to a HD monitor (1920 x 1080). So could this be a graphic card issue?

Some points to note:
1) Windows XP (yes I still have it) is running very smoothly.
2) I also tried running Parallels (Windows 10 from my Bootcamp) and it doesn't run slow too
