== Test Setup ==

Running [http://www.geeks3d.com/gputest/ GpuTest] 0.7.0, on a Fedora 22 system with a [http://www.geforce.com/ GeForce GTX 760], kernel 4.0.5, [http://www.nvidia.com/Download/index.aspx nvidia driver] 346.59 at 1280x720 resolution.

The [http://www.vmware.com/products/player vmplayer] tests below start the same tests in a Windows 7 Ultimate 64-bit virtual machine using VMware Player 7.1.0 build-2496824.

The xpra tests were using a local socket connection with mmap and displaying with opengl rendering, which obviously eats up a little bit of GPU power.

== Observations ==
* virtualgl adds some overhead which is most noticeable when running on bare metal, hardly noticeable when running through vmplayer as it slows down the opengl performance considerably already.
* running through xpra actually gives a performance boost in some cases, probably because it does not need to wait for the actual screen refresh since there isn't one.
* wine shows high performance, even faster than bare metal, but some tests display with quite a lot of stuttering, the stuttering goes away when running through vgl, but so does most of the performance..

Note: [https://www.virtualbox.org/ VirtualBox] 4.3.x failed to launch any of the tests and is not included here.
