I ran into some strange problems again, this time with the 388.13 driver.
So I closed every software in the task manger which isn’t necessary for win to operate.
Then I run 3dmark Time Spy, result: 9112 points
2nd test I started PiPlay 2.5 (latest and downloaded from the website here), result: 8646 points
3rd test I closed the all PiPlay processes, result: back to 9147 points.
I will run some test with older versions of PiPlay now to see what’s happening.
Question is why is the PiPlay software eating up so much performance and causing for example Project Cars 2 not going above 45 fps, no matter what settings.
