But, you know, rF2 graphics engine can be a nightmare sometimes. I got FPS figures above 200 or even 300 in some track regions but it's still not a smooth gameplay for any reason. I got to mess up with Nvidia Inspector, screen setups (bordeless, windowed or full-screen) and multiple combinations of V-Sync types and no Vsync at all to reach a "acceptable" smooth gameplay, even though it's not fluid as other titles as F1-2018, AC, ACC, AMS or PC2. I really don't know what happens but I can feel rF2 is not running at the FPS numbers shown through Control + F. In the picture you can see more than 200 FPS and low CPU (i7-8700K/32Gb/1080Ti)
The problem with "smooth gameplay" is that it's not just a thing of framerate. For an image to be perceived as completely smooth, you also want the framerate to be as close as possible to a whole number multiplier of your refresh rate (because if it isn't, then some frames will be skipped, introducing perceived microstutters and/or unsmoothness - that's also why vsync on will generally give you the smoothest image if you can get the framerate high enough). And, perhaps more importantly, you ideally want the framerate to stay there, because jumps in the framerate are always very noticeable, even if the framerate itself is high enough.
It can be quite difficult to get the framerate in rF2 to be stable enough, because its framerate can vary quite a lot even from corner to corner, so even though your framerate is high, it is still all over the place and you will notice that. And basically the only way to keep it under control is to use some form of framerate limiting - so you keep the framerate locked at certain lower value (again, ideally close to a whole number multiplier of your refresh rate) and don't let it go any higher, even if it could.
It's hard to say what you should try on your system, but for a very smooth gameplay, what I do is this. I run the game in borderless window (fullscreen has less issues with smoothness for me in rF2, so it would be preferred, but I want to be using SimHub overlasy and those require windowed mode). I am using vsync - the "video" setting in rF2, the other ones are not suitable for what I do next. I have figured out my *exact* refresh rate using sites like
https://www.testufo.com/refreshrate - my actual refresh rate on my pleb 60 Hz monitor is 59.95. And I use this to limit my rF2 framerate in Afterburner to 59.94 fps - in other words, to a value that's 0.01 fps lower than my refresh rate.
Doing this gives me very smooth gameplay, but with a very low input lag - it is smooth because I'm running with vsync on, but that -0.01 fps limit trick lowers input lag significantly compared to running vsync on without it (I can't tell you how exactly this works because I don't really understand it myself, I just know it works).
An even slightly better option for me would be to run vsync off (because the input lag would be lower still) and limit my framerate at 120 (double my refresh rate), but I can't hold stable 120 fps in rF2 consistently, so the end result is less smooth than the above. And limiting at 60 with vsync off is a no-go for me, that gives me random microstutter in borderless window (would probably work in fullscreen).
So these are some tips for you that you can try.
