Rivatuner - it's a 3rd party app that does frame limiting, among other things. Worth a look at as very effective. In that post I compared with Chill and the borderlands 3 in-game limiter and got broadly similar results. I opted to use chill with 70-70 limits rather than RTSS as didnt want another app running alongside the AMD one which I use to OC.
There's another post I did on page 913 about 10 down which is probably more helpful for what you are trying to do. Basically when I set the Chill range to the same as my freesync range, 48-75, the average fps was 61. So that's quite a lot of lost performance but the payoff is a very significant saving in power and temp. It depends whether you want to optimise performance or power efficiency as to what range you use. Chill is not a frame limiter - it optimises power efficiency but boosts up performance based on mouse speed, although in my testing normal play movement was not enough to max it out. The only way to get it to behave like a limiter is to set the min and max at your target framerate and even then you should drop down a few fps since actual fps fluctuates and will occasionally go above your monitor max. I would only enable Chill in games where the framerate exceeds the monitor max. You could set globally and and I'm sure it would be ignored in games which fall below the limit with no detrimental impact but I prefer to set just for the games that need it. When fps exceeds the freesync range you will be at the mercy of whichever tech you have chosen to use - enhanced sync or vsync (or neither). I use enhanced sync in case of this. Equally important is keeping the minimum fps above the lower freesync range limit but Chill wont help you here - only reducing the game perf settings or resolution will do that.
Spot on. Try 140/140 Use the overlay and perf metrics built into the new driver with a game benchmark and write out to a file so you can analyse how many frames go above 144. If more than 1% I'd suggest dropping below 140/140 and retesting. The new metrics are one of the really useful features. No idea if FRTC will make a comeback - it's not on the list of features you can vote for so I suspect not
RTSS is a proper frame limiter and works very well. But in my testing Chill did the same job with 70/70 limits as RTSS did with a 70 cap. Hence I went with chill as 1 less program to launch at startup
Cool disco mode. Looks like it massively improves the game.
I wouldn't bother. The comments tell you all you need to know and way more entertaining
