the test: open a long webpage in the guest, scrolling down.
amd threadripper 1950x + VirtualBox 6.0 = choppy guest video (all display options tried, vmsvga vboxvga, reinstall of GA etc)
amd threadripper 1950x + VirtualBox 5.2 = smooth guest video
intel 7820x + VirtualBox 6.0 = smooth guest video
the below topic looks like the same issue, the problem should be caused by incompatible of amd and vb6.0.2
t=91320, VBox 6.0: 2D acceleration is on but video performance on Windows 7 host is very choppy.

Re: VirtualBox 6.0 on threadripper performance issue
Then please do as they did on that thread that you quoted... We need to see a complete VBox.log, from a complete VM run, where the problem occurs:
- Start the VM from cold-boot (not from a paused or saved state) / Observe problem / Shutdown the VM (force close it if you have to).
- With the VM completely shut down (not paused or saved), right-click on the VM in the VirtualBox Manager and select "Show Log".
- Save only the first "VBox.log", ZIP it and attach it to your response. See the "Upload attachment" tab below the reply form.
Do NOT send me Personal Messages (PMs) for troubleshooting, they are simply deleted.

If you obfuscate any information requested, I will obfuscate my response. These are virtual UUIDs, not real ones.

Virtualbox V6.0 super slow video on AMD CPU
VBoxSVGA and VBoxVGA, with or without 3D 2D is also tested,
Intel 7820x + nvidia do not have problem,
but on AMD 1950x + nvidia, the windows 7 guest graphic is very slow
Test method: start win7 guest on the amd computer, open file manager or chrome, use the mouse to drag the windows title to move it around the screen.
The log is attached

Re: VirtualBox 6.0 on threadripper performance issue
- You opened a thread in the "Linux Guests" area on 2019-04-01: "VirtualBox 6.0 on threadripper performance issue".
- I ask you for a log. You ignored that...
- Instead of a log, almost three weeks later, you open a thread in the "Windows Guests" area on 2019-04-19: "Virtualbox V6.0 super slow video on AMD CPU".
- Guess what's going to happen? I merged your two threads and moved them on the "Linux Hosts" area (common denominator).
- I'm going to analyze your only provided log, assuming that the issues in your first thread are common with the ones on your second one...
That's a huge display to handle with a fake/virtual GPU. Try to lower it to something more sensible, like 1280x1024. Also, you could enable 3D acceleration to make this smoother, and switch from "VBoxSVGA" to "VBoxVGA" as your Graphics controller.00:00:00.716532 VMSVGA3dEnabled <integer> = 0x0000000000000000 (0) 00:00:00.716533 VMSVGAEnabled <integer> = 0x0000000000000001 (1) 00:00:01.336743 VMMDev: SetVideoModeHint: Got a video mode hint (2349x1633x32)@(0x0),(1;0) at 0

Re: VirtualBox 6.0 on threadripper performance issue
sorry for the late reply,
but I test the issue again after the new version of virtualbox 6.0.6 released,
as I think many people is using amd cpu it should be solved without my further test log.
same amd hardware, same test method, virtualbox 5.2.28 do not have any problem, it can handle this high resolution smoothly.(most people is using 4k monitor, 2349x1633 vm is only using about 2k)
but on virtualbox 6.0.6
the problem in windows guest is more serious than linux guest, but only on the amd cpu, my intel computer can handle this high resolution smoothly on vb6.0.6 and 5.2.28.
therefore I posted the issue in the windows guest forum.

Re: VirtualBox 6.0 on threadripper performance issue
I remember that I have also test windows 10 as host last month using 6.0.4,
when it is AMD cpu, the guest graphic is also very slow. but Intel CPU is smooth.
linux guest or windows guest in VirtualBox 5.2 is smooth with both amd cpu and intel cpu in both linux host or windows host
linux guest or windows guest in VirtualBox 6.0 is slow on amd cpu but smooth on intel cpu in both linux host or windows host
when it is AMD cpu, the guest graphic is also very slow. but Intel CPU is smooth.
linux guest or windows guest in VirtualBox 5.2 is smooth with both amd cpu and intel cpu in both linux host or windows host
linux guest or windows guest in VirtualBox 6.0 is slow on amd cpu but smooth on intel cpu in both linux host or windows host

Re: VirtualBox 6.0 on threadripper performance issue
Hi, any update on this issue. Am facing the same thing with amd 2700x. Also attaching the log of my windows 7 guest running in windows 10 host with virtualbox6. The problem doesn't happen if virtualbox 5 is used. Tried enabling 2d and 3d acceleration but same result. Thanks.

Re: VirtualBox 6.0 on threadripper performance issue
Try setting the graphics controller to VBoxVGA (not VMSVGA or VBoxSVGA).
Increase the number of CPU cores to 2.
Eject the Guest Additions CD.

Re: VirtualBox 6.0 on threadripper performance issue
I'm also suffering this.
No errors. Just everything. runs. slow.
One win 7 guest (2 cores, VBoxVGA) a 15min make now takes close to 25min. Using scroll wheel slowly motors up and down.
It's like the hardware acceleration (amd-v etc) arn't being used.
2d/3d acceleration no great difference
AMD 8150 8 core. Mageia 6. Vbox 6.0.8
