I got horizon 3 to work by setting the frame rate yo uncapped in settings. Unfortunately I can't seem to add a custom profile in rtss so I can use that to cap the frame rate. I can set a global frame rate for it but I don't want all my games capped at that fps..

You should be able to set an RTSS profile for the game, you just have to take ownership over the Program Files > WindowsApps folder first. It is hidden and locked at default.

This page has a step-by-step guide for unlocking the WindowsApps folder:

I have access to that folder but the executable itself I don't have access to. I get an error when I try to add the executabl. It did take some work to get access to the folder itself.

Launch the game, then press shift + the add profile button in RTSS. It should open a dialog with all currently running 3D apps.

I did that too while running Forza and it didn't appear on the list unfortunately.

I welcome further input, questions, and discussion regarding the G-SYNC 101 series, or G-SYNC functionality in general...
After reading your tests, it is better with G-sync to cap fps 3 frames below refresh rate,
i was wondering if with non G-sync monitors like most BenQ, would it still matter or uncapped fps would be better ?

@casinca,

I don't know if you missed it in your first read through, but the "G-SYNC vs. V-SYNC w/FPS Limit: So Close, Yet So Far Apart" and "V-SYNC OFF: Beyond the Limits of the Scanout" sections in my "G-SYNC 101: Input Lag & Optimal Settings" article already answered that question.

I'd try to repeat my answer here, but the subject is too multifaceted without knowing what you specifically want to achieve with your configuration. Short answer: it depends.

Please read those sections, if you haven't already, and check back here if you need further clarification.

Thanks for replying,

I didn't notice that you could scroll left and right for the other refresh rate graphics, i can see the other results now.

But besides that, where i'm not sure on "V-SYNC OFF: Beyond the Limits of the Scanout" is when you compare on the graphic :
"G-SYNC + V-SYNC" and the others "V-SYNC OFF" with different FPS limit, is "V-SYNC OFF" on the graph means "G-SYNC ON + V-SYNC OFF" or "G-SYNC OFF + V-SYNC OFF"
My question was more about seeing input lag results of "GSYNC OFF + VSYNC OFF" with different FPS limit, so if this is the same thing and doesn't matter, then it's all good but wanted you to confirm to be sure. Thanks
Hope its not too confusing :oops:

Sorry i love this stuff so i had to butt in and reply. "Gsync off and vsync off" should maintain a low average input lag even over the refresh rate of the monitor. Because it uses vsync off behavior when it is above the gsync refresh. You might notice tearing and a desync of fps and monitor refresh may create a microstutter. But on average the input lag will be similar. The only time it would not be similar is when the game engine uses techniques that make input lag and framerate relationships. Like in overwatch you might get more input lag if the graphics part of the pipeline is too slow. However this is very unlikely at the high refresh rate of a monitor (144fps or above for example). And if it is happening you can always turn down a graphics setting to eliminate it.

Yes, if you're on mobile, you can either swipe the charts or tap the large grey dots below the charts to cycle through them. On desktop, there are both left/right arrows and dots.

"V-SYNC OFF" = G-SYNC and V-SYNC completely disabled.
"G-SYNC + V-SYNC 'Off'" = G-SYNC enabled and V-SYNC disabled (this scenario was featured earlier in the article).

To be clear, all the entries labeled "V-SYNC OFF" in the "V-SYNC OFF: Beyond the Limits of the Scanout" section have both G-SYNC and V-SYNC completely disabled.

I acknowledge the information in the article can be a bit overwhelming (and even confusing), but that's just the nature of the subject material; it's complicated stuff ;)

If you have further questions, don't hesitate to ask them.
