Windows 10 guest is very slow

Post by aauy89 »

Hi!

I've just installed Windows 10 and I'm having huge performance issues. When I click the start button I have several seconds before I can see the menu. I've tried adding more ram, more CPUs, 3D accelerations on/off, different chipsets, but nothing solves it.

I have 32 GB of RAM Macbook Pro (Big Sur OS) with 8 GB allocated to the VM.

Please find the logs attached.



Thanks in advance for your help!

Hi

I don't know if this will help, but I am a Windows 10 user and had/have quite a few problems with it myself.

You could try opening Command Prompt as an Administrator (right click) type sfc/scannow and let it run.

That way you can hopefully then tell if its a Windows problem or a VirtualBox problem.

I very much doubt that will be useful. I would expect that the OP means that graphics are slow. IMO the most likely cause would be because he's running in fullscreen mode with no 3D acceleration.

Thanks, Bit-tech and mpack for your responses!

Yes, the start menu was just an example but all graphics are slow, I'm seeing the issue when I'm typing, dragging windows or when using the browser.

I'm running in fullscreen scaled to 200% and when 3D acceleration is enabled graphics get worse. I'm not sure what's causing the issue but the VM was working fine before upgrading to Mac OS Big Sur.

Thanks for your help!

If I was you I would re-enable 3D acceleration and then concentrate on why it is still slow. With 3D acceleration disabled there is nothing to solve - a 2K display with no graphics acceleration is guaranteed to be slow.

I do see this in the log.

I don't know Macs. Do you have a decent graphics chipset? Updated drivers? Have you run an OpenGL test on the host? Note that host support for OpenGL is vital, it's how a cross platform app like VirtualBox gets access to graphics acceleration on each platform.

FWIW, I see the same log messages for a well-behaving Windows VM on my macOS host, as long as 3D acceleration is turned off in the VM configuration.

My guess is to enable 3D acceleration. You might need to re-install Guest Additions. Then disable Settings > Personalization > Colors > Transparency Effects in your Windows guest.
