Nvidia G-SYNC kills 3D performance in Performance test

[wonderwrench]

Enabling G-SYNC kills 3d performance in Performance test 9 build 1023. Each version of DX is affected more the newer the version of DX being tested. If I run 3Dmark demo or any tests from the payed version there is less than 2% difference in the results with G-SYNC on or off. Seems strange to me, any ideas. See baseline # 952635 for basic system info. Some info may be incorrect do to driver updates etc.

G-SYNC limits the frame rate to the monitors maximum refresh rate. If you are running a 3D application that creates frames faster than the refresh rate, then the frame rate will be limited.

I'm new to G-SYNC so still learning. With what I understand you to be saying using my own possible backward logic I would think the older versions of directx would take the largest hit do to the high frame rates and the limit of 144hz. But its just the opposite. 144hz G-SYNC monitor has a greater hit in performance with G-SYNC on with DX12, frame rates in the 30 range. You would think any frame rates under 144hz would not be affected at all. Very strange IMHO. Big thing is I know G-SYNC should be disabled when bench testing or if you have performance problems in certain games. And thanks David as always your the man! P.S. I wish PT9 had an option to show the results in the old format. Much easier to work with and gives more info in one place.
