SteamVR Poor Results

[paecific.jr]

I downloaded the SteamVR Performance Test today to see how my computer would do. I was shocked. My cpu, dual Xeon E5405 @ 2.00 GHz, passed; but, my Sapphire 390x failed.

My overall score was "Not Ready".

Average Fidelity - 3.1,

Frames Tested - 5321,

Frames Below 90 fps - 676 (12.7%),

Frames CPU Bound - 7 (0.1%). 

 

What is my problem here? My system is using PCIe 2.0, however, test after test have shown that PCIe 2.0 doesn't bottleneck a system that much. Any ideas?

The test is the issue. results seem really inconsistent, with some 280s being ready and 390 and 390Xs not being ready. My Titan Blacks aren't ready either, according to the test.

That would also explain why my cpu passed
