Not getting full GPU utilisation

Keep in mind that you're looking at thread usage, rather than core usage. Each core is dealing with two threads. I've found it usally the case in real world tasks, rather than synthetic benchmarks and stress tests, that you can reach the limits of your CPU (or at least one core) and still have the overlay say it's not at 100% usage thanks to Hyperthreading. You could try going into your BIOS and turning that off and then see if you're hitting 100% usage on the CPU (obviously you'd want to turn it back on afterwards). Another good test would be to turn DSR on in the driver control panel so that you can up the game rendering resolution to 1440p. I'd guess your framerate won't change much, if at all. The 2080 Ti really isn't a 1080p card and even a 9900K at 5GHz will create a bottleneck for it much of the time at that resolution. Faster RAM helps somewhat in CPU-bound scenarios, but you're never going to get 100% out of the card at 1080p all the time. GPUs have simply advanced too far beyond CPUs at this point.

That quite clearly says that you are running at max 97% gpu usage at some point.
Turn g sync off its only needed if you are getting below 100 fps.
@Dumphole
You could always swap your 8700k for a 9700k and try for 5.2ghz.
You can get them new for about 330 but you might find one cheaper second hand.
But it's not going to be much difference. Benchmarks here

The issue isn't the cpu.
It's g sync and 1080p.
He's hitting 270fps he says so when g sync drops it to 240hz then obviously the gpu isn't going to be pushed to its max.
He needs to up the Res which he can't without buying a new monitor.
Therefore he needs to either Ip the settings to ultra if not already.
Or turn g sync off and put fps on unlimited. He needs to turn any fps cap off.

Up the resolution to 1440p via DSR. That you can enable and setup in the nvidia 3D settings and then select the desired resolution in the benchmark/games you are looking at. If the GPU runs up to max then 1080p is the issue.
IMO the 2080Ti isn’t built for 1080p. Buy a 1440p 144hz/165hz/240hz etc monitor or use DSR. The frames you will lose due to bottlenecks will be next to nothing. Yet you will be able to enjoy the higher resolution.
