What happened?

Sorry for responding so late.
I had to ask all my co-workers to see if someone is having an windows machine at home.
Apparently NONE, neither their family members have or use windows machines, all are Apple.
The strangest thing, is also that some said that some family members switched from Windows 10 to 11 and after they switched completely to ZorinOS !
I had to check that name out, never heard of it....until i spoke with our colleagues from Germany and they said that they already started to pack from Microsoft and already preparing/testing the total switch to Linux.
So i guess this in Germany also is seriously taken.
I am a manager of a very large software company and i did an experiment once by adding an Apple M4 mini desktop to an oversized dinosaur Window machine AMD threadripper 64cores....
Everybody was mocking the Apple M4 Pro mini desktop..and even the person who was using it called him the "Little Guy"....
But once the "Little Guy" started working with the M4 Pro the funny part was that the creation timing was reduced by much in a way that he even started to do in advance further project(s)....
And soon the other(s) "oversized dinosaurs windows desktop machine" become so curios and so ashamed that i had multiple request(s) of switching them to "Little Guy".
So in the end i had to buy over 60 mini desktops Apple M4 Pro to all team.
In the end having the biggest office as manager i had to cope store in my office over 60 oversised dinosaurs windows desktops, to a point i had only space to only reach my desk.
Luckly i managed to post an add and i sold them for a fair price. But first i even asked other departments if they want them....all said no thank you we are moving away from Microsoft like forever.
Unfortunate we still are bound to use an actual windows machine, in the form of the last windows machine a laptop that for compatibility reasons we cannot dispense (for now) but i will since all other mock me for still having an windows machine. So i had to hide it in the drawer. and put an a4 paper add with title "No Windows Machine Here".

So yeah it seams that the love for windows is so low that people actually don't have to deal with it anymore and entire departmenst even country's like Germany is switching to Linux and OpenSource.
Also on Linux can be fully used QEMU + GPU pass for fully 3D Acceleration.

Anyway returning to the 3D part of virtualbox. not so good, i mean not so god at all.
Ever switching from QT 5 to QT 6 this virtualbox has become a consistant bug collector. Nothing works anymore.

Strong suggestion either make a full 3D Acceleration priority for virtualbox or close shop.

You can't have a "3D Acceleration" function/option in virtualbox under graphics that the best ot can do is to accelerate from 2 FPS to 10 FPS in all 3D content, regardless if DX9 or DX11 content.

Please no need to ask me in what.... just test yourself we all know it !

Again fix it or close shop. Since virtualbox is the ONLY one vm that can't accelerate anything !
VMWARE and even QEMU can accelerate 3D content to it's maximum potential. And i do not want to talk about Parallels since it is a payed product.

So what are you all waiting for.... chop-chop fix the 3D ASAP !

How can we reproduce this?

3D Acceleration is broken !

Did you upload all of your necessary log files, screenshots, etc.?

• Yes, I've uploaded all pertinent files to this issue.

What is wrong with you? If you continue with creating useless issues which just waste everyones time I'll ban you from this repo, period. Take this as the first and final warning.

There is no additional information compared to the last report you opened about the same issue, and your anecdote about Windows and macOS is completely besides the scope of the ticket. And if you are not willing to describe the usecase you have issues with we can't possibly help you. 3D is such a complex machinery inside the guest and on the host that you can't possibly expect us to create a reproduction scenario out thin air and ramblings you produced.

And don't tell us what to do, espcially when you are using VirtualBox for free, this is just plain rude. This bugtracker is run on best effort as we only have very limited engineering capacity.
