AC19 3D Explore window 'drifts' when stopped

[Jeff Kogut]

Built a new PC this week with Windows 10, Quadro P600, and have AC19 and AC21 installed. AC21 has no issues.

I have several projects to continue work on in AC19 and now when I move around in the 3d Explore window and then stop moving the view slowly 'drifts' in the direction I last moved. This applies to side input from the mouse and panning/up/down movement from the keyboard. I need to put in some counter input with the mouse to stop the drift. Not a show stopper, but annoying.

The only time this doesn't immediately happen is if I'm moving directly forward and then stop.

I had previously started this file on an iMac.

I checked the work environment. Latest Quadro drivers. All Windows updates. Any ideas?

Maybe a mouse driver issue?

I haven't used ArchiCAD19 for over a year, since we run everything on ArchiCAD20 now, even the projects started in 19, but I do not recall having this issue on Win10 at the time.

The one thing I didn't even consider Erwin! Alas, it's just a MS Wheel Mouse with vanilla driver and I can't seem to turn anything off to change this.

[Erwin Edel]

I don't suppose you have ArchiCAD20 as well? I have no issues with any projects from 18/19 in ArchiCAD20.

I notice you are running two 4k screens, maybe ArchiCAD19 doesn't like the high res as much as 20/21.

[Jeff Kogut]

We're transitioning to 21, but I have some projects I'd like to keep 19.

[Erwin Edel]

With the stair tool (and teething problems of 21) I can understand that. 20 is working fine, also for 19 projects, you just get the UI update (and properties and some other updates), but I suppose it is 19 or 21

Maybe try running the screen at half resolution to see if that is causing it.

[Erwin Edel]

Should also say I am running two HD screens, not 4k here.

$310 each.

I like them, though the color is not quite up to the Apple 5k i5 system I was using but those LG monitors Apple uses are $1300 each.
