After i did the Windows 10 october update (build 1809) on my machine, i managed to complete the test with nearly no issue at all ! The only problem is with the resolution which is stuck at 1536x864 instead of 1920x1080.
The Performance Test automatically scales your resolution to reduce bottlenecks which may cause unrepresentative performance for your system. So this behavior is expect. Of course, you will be able to manually set your resolution in the game.
