The big number your counter shows is an average, and the average hides exactly what bothers you.
A machine running at 90 frames that drops to 45 at the start drives worse than one locked at 60. Because the stutter always arrives at the worst moment: when there are twenty cars around you, which is when you need the most precision.
So the goal isn't "more FPS". It's never dropping. Two practical consequences:
In order of what gives back most for the least cost to driving:
These settings aren't decoration: they're information you need to drive.
If you can only change one thing: the number of visible cars.
Every car on screen costs geometry, shadows, reflections and physics. It's the setting that explains why you're smooth alone and stuttering at the start.
How to use it sensibly:
And something almost nobody checks: overlay apps. Telemetry, dashboards, live graphs. Each one is drawn every frame. Keep the two you actually use and close the rest.
Proof you got it right: you do a start with a full grid and feel no stutter at all. If that's true, anything else you could raise is optional.
If you're on VR or triples the bar is higher: covered in triples or VR. And if the machine is short to begin with, check the requirements before spending.
Stable above your screen's refresh rate is ideal. A locked sixty drives better than ninety that swings: what ruins a braking zone is the stutter, not the average.
Don't turn them off: you need them to race with people. What you can do is lower their resolution and update frequency, which gives back nearly as much.
Quite a lot. A stable cap avoids peaks and troughs and makes delivery uniform, which is what you perceive as smoothness.
Yes, and it's one of the biggest gains. But be careful: drop it too far and distant cars and boards become unreadable, which costs lap time.
What it is, why it rotates the car, how to practise it and the mistakes that end in a spin.
