FPS drops when using G-SYNC or capped FPS

[BottleneckHunter]

I have this odd behavior of whenever I cap my framerate to 141 fps for my Dell 144hz 1440p G-SYNC monitor I always get about  20-30 lower fps right off the bat. On top of that I get crazy amounts of input lag and worse frame times. I also get random stutters and hiccups if I use G-SYNC or even just cap my fps which has made G-SYNC unusable for me. I have attached my dxdiag. 

 

I have followed the blurbusters setup guide but it does not help. The only solution is to not cap anything and have gsync disabled and basically just run as much fps as possible even sometimes over my refreshrate. 

Any help is appreciated.

Is my new build

1. What are you using to cap the framerate?
2. Did you make sure to turn off V-Sync?

I have used Nvidias built in fps cap in the control panel and have separately tried through after burner and through individual games 

 

I have tried with it both on and off.

Turn off V-Sync, enable G-Sync, and use Riva Tuner Statistics to cap the frame rate to less than your minimum framerate.

This is so weird. Why is it that Rivas FPS cap works and not the built in NVIDIA one? I played COD MW for the first time with Gsync working and it was really good. I also tried a few other titles that were giving me issues like Diablo 3 and The Division 2 and it seems like its working now I guess.

Framerate caps work different.  I don't understand the details (I remember a Gamers Nexus video went into detail on it awhile back), but it's why I use RTS.

 

Anyway, I set the global framerate cap to 143FPS (my max refresh rate is 144hz, so that keeps G-Sync working without tearing), and for individual games that have unstable frame rates, I will set a different cap for that specific program.  You can use the Add option for that.
