As the subject says, I'm running Win10 64-bit guest on a Win7 64-bit host. 3D rendering is not working. Apps that attempt it exhibit some combination of crashing, showing a blank window, or saying they encountered a problem. Below are the specs and output from Novabench. Attached is a VB log. Thanks for any help!

Virtual machines will never be as powerful as the host, especially on the video side. They use after all a virtual graphics card, not your host's real graphics card. Applications that have high requirements on the GPU (drawing, 3D, games, video) are expected to not work as good as on the real hardware, if they work at all.

You only option is to pretty much wait for improved graphics support. I have no clue when this will happen, or if it will happen at all.


PS. For future reference you should ZIP your logs. It helps save a (virtual) tree or two...

I see several mentions of Direct3D11. In fact as you'll see in the user manual (section 4.5) Direct3D9 is the maximum level of Direct3D support currently offered. Apps that rely on higher levels will not run, or they may run and crash.

Hmmm... Thanks for the replies, although I wish their content was more positive. Honestly, I don't care about the performance of the 3D rendering, just that it renders the scene so I can click on the objects in it. Kinda like an old CPU doing video compression, it won't do it well, but it will eventually do it. That's all I need. I guess it also doesn't help that I'm not entirely sure what 3D library is used in the app that I need to run, but I believe it's OpenGL. Oh well. It's not super important.

In that case you should possibly turn off 3D acceleration entirely in the VM settings. That will force the guest OS to use software rendering only, with performance drops as you might expect.

Thanks for the suggestion, but that didn't work. However, I did find a way around my problem that doesn't require a 3D scene render so I'm good.
