Using FastSync with a Maxwell-based 980Ti

So for now, I still have my old monitor which is 1920x1200 @60Hz.

 

At first, I thought that only Pascal cards supported FastSync - the main reason I was originally going to buy a 1070 (but dropped it due to the price rise), but I was setting up the NVIDIA Control Panel (which is utter garbage btw) and I found this:

So it looks like Nvidia added Maxwell FastSync support with driver 372.54, now a few questions:

 

Since this feature is designed more-or-less to combine what V-Sync does with lower input lag, if I enable it in the Control Panel, what should the in-game V-Sync setting be?

I suppose it should be turned off, as it could potentially override the Control Panel setting, right?

 

Another question: What if I wanted to use a framerate-limiter as well? Would FastSync work if I capped framerate of a game to reduce heat, noise and power draw since such a card is basically overkill for my current resolution?

Also: Does running the game in Windowed/Borderless/Fullscreen matter for FastSync?

 

Thanks guys!

The way I do it is on a per-game profile, with the in-game Vsync off (or used to without SLI, it's not enabled on SLI). You can also use a framerate limiter, I used to as well. Regarding borderless or windowed mode, the Windows Desktop Manager takes over and syncs output, but slower and more inaccurately(it's fairly alright in most cases, but input latency will be greater). So I'd suggest avoiding those if latency is your prime concern. On the other hand, if you do use borderless, the latency will be a bit less than Vsync.

If you choose Fast it doesn't matter what's set in-game. The Nvidia Control Panel will override it
