I'm running Android x86 6.0r1 in a vmware virtual machine and the new graphics driver works really well with the improved 3D acceleration feature in vmware player 12. Its easily as fast as something like Nox and has excellent compatibility with the games I tested. I'm getting a solid 60fps and very few graphical glitches even in heavy 3D games on my GTX 970 which is awesome.
Unfortunately the vmware virtual SVGA driver only seems to support a very limited range of resolutions with the maximum being 1152x864x32. This is the same in a Windows guest when running without vmware tools installed. So I did some digging and found this interesting project:
Is there any interest in porting the open vmware tools source to Android x86? this would really increase the usefulness of it running in a VM - custom resolutions, full screen support, arbitrary scaled windows, copy and paste, shared folders etc. Considering the limited range of hardware that is actually compatible with Android x86 it could really help attract people to the project as well because you could publish a fast, slick vmware image which would "just work" on a much wider range of PCs and even Macs.
While I'm here could I also mention that ethernet configuration is a bit tricky in Android x86? there's no UI to set a static IP address or even check that things are working (though out of the box they are but via DHCP only). In Remix OS there is a very simple ethernet configuration panel in the settings - could this be backported to Android x86? I'd really like to see that in a future update and it would no doubt be beneficial to people on desktop PCs.
