Ryzen 9 3950x and GTX 1080 3D performance issue.

Hello,

I think this may be due to the new version of performance test 10, but now when I benchmark my GTX 1080 with my 3950x I am getting around 8k as the result vs the ~16k I usually get. I am currently running an x570 Asus mITX motherboard (only one PCIe 16x slot). I have tested in an 8700k rig I have and the compute results look normal.

It appears fine when going through the Dx 9, 10, 11, and 12, but when it gets to GPU compute doing the physics calculations it is extremely slow.

Has anyone else seen this on an AMD platform, and any thoughts on how I can fix it?

Can you post the actual result you are getting for the 3D tests?
What monitor resolution are you running?

So I feel pretty dumb, but re-seating the card appears to have resolved the issue. Its possible it wasn't using all 16x lanes. I have posted the results now, but I think this is a case closed .

This kind of stuff happens all the time, even after doing it for 30 years.
