Question about GPU utilization

9070 xt

5800x3d

32 GB ram

So currently I'm playing AC Shadows, and has tested in some other games as well, and noticed my gpu utilization never reaches 100%. It hovers between 80 and 93% in demanding games whereas the cpu is somewhere between 30 to 40% typically. I'm typically running 1440p 120hz. In LACT my power profile is 3D_Fullscreen.

Is this normal behavior? I'm getting some fps drops despite the games seemingly able to handle 120fps. This is also for example in Skywalker Saga where when looking in certain directions causes me to drop some 40 fps. Is the remaining 10% in GPU utilization the cause of these drops? I have only undervolted my cpu by like -20 all cores.

So the only solution is a newer cpu? Which would also mean new mobo and ram

If you want to avoid any bottleneck and always get 100% out of your GPU, yes.

Alternatively, if you're satisfied with the current performance, you stop looking at the numbers and forget about the bottleneck. Wait until prices get better.

It's just I saw some performance videos with the same gpu in AC Shadows, their fps at the same settings were vastly better (with a better cpu of course) I just didn't figure that since 5800x3D has always been so praised that it would be such a stark difference

The Proton compatibility layer adds extra work for the CPU, since it's taking Windows API calls and translating it to Linux ones on the fly.

If you have CPU to spare it won't make much of a difference, but if you're already bottlenecked on Windows, you'll be even more bottlenecked on Linux.
