#9799 fixed 3D Acceleration Not Working -> fixed as of 27 Oct 2011 Clayton Carney

#5206 fixed 3D Acceleration Should [Try Harder To?] Free Textures On Application Exit -> Fixed in SVN fullreset
Description

The Problem:

  • Tracking texture IDs returned by OpenGL in the Guest OS across several application launches suggests that under abnormal termination (eg signals, incl SIGINT) makes no attempt to free textures.
  • Furthermore, many applications are 'sloppy' about freeing textures, assuming that the OS/libs will do so when the program ends (regardless of cause.)

Suggested Solution:

  • Texture state should be tracked throughout the life of the application, and when/where possible textures should be 'collected'.

Notes:

Only tested with Linux Guest under Mac OSX Host; this problem may exist elsewhere.

#17368 duplicate 3D Acceleration and Unscaled HiDPI Output bug sjchoi
Description

I have three problems.

[1] "Enabling 3D Acceleration" causes screen detach.

See "3D Acc.png". Steps to reproduce:

1) Install a Windows 10 guest on a Mac host. 2) Enabling 3D Acceleration in Settings > Display > Screen. 3) Boot the Windows guest.

[2] "Enable 3D Acceleration" and "Use Unscaled HiDPI Output" causes screen detach and distortion.

See "3D Acc & Unscaled HiDPI.png". Steps to reproduce:

1) Install a Windows 10 guest on a Mac host. 2) Enabling 3D Acceleration and Use Unscaled HiDPI Output in Settings > Display > Screen. 3) Boot the Windows guest.

[3] Using Unscaled HiDPI Output in Integrated Graphics is very slow.

Steps to reproduce:

1) Install a Windows 10 guest on a Mac host. 2) Use Unscaled HiDPI Output in Settings > Display > Screen. 3) Uncheck 3D Acc to use Internal Graphics. 4) Boot the Windows guest. 5) Set "Custom Scaling" to 200% in Settings > System > Display > Scale and layout in Windows. 6) Log out and in to apply.

In this state, the virtual machine is very slow and laggy. Can there be any optimizations so that I can use a retina Win 10 guest without any lag?

7) It goes well if disable "Custom Scaling" in the guest and set "VirtualBoxVM.app" as "Open in Low Resolution" in the host. See "Low Res.png".
