CPU Bottleneck? Ryzen 9 3900x & RTX 3080 Ti

It’s impossible to diagnose what the Nvidia card is doing. It’s clear when you compare RDNA2 to Ampere, that Ampere is using a lot more CPU time, but what is actually going on is a mystery because of Nvidia’s black box approach. I don’t even think games developers have the ability to see what is happening.
 
latency in ms for GPU and CPU in warzone.
GPU time: 3-4 ms
CPU time: 9-11 ms
Very good initial analysis.
This is aligned with what you are experiencing. GPU is fast enough to run 250+fps (1000/4ms/frame = 250fps), while CPU is struggling to reach 90-110fps (1000/11 = 90 fps).
So clearly CPU is holding you back.
I would guess that nothing is actually wrong with your settings. Maybe some 5% could be gained by spending time to overclock CPU and memory, not worth it imo.

To get a bigger improvement, upgrade to Zen3 5800X as recommended above.
This alone should give 15+% fps in warzone, without changing anything else. And it opens an option of getting faster memory later (3900X will struggle with anything above 3200)

5900X and 5950X will be a marginal gain over it (say 1-2%), although I am not familiar with warzone and how much it likes additional cores.

PS. Stumbled upon this, may be worth a try:

anyone ever tried the 1usmus ClockTuner for Ryzen?
Did some research and seems like an "easy" overclock for a beginner like myself

Unless it's somehow been improved I seriously wouldn't bother. I used it on my 3900x and it was great for a high cinebench or other artificial benchmark, but gaming performance was dreadful.
 
You will want a 5950X and tuned RAM to get the most in Warzone (or a 10900K) - I don't think Zen2 will cut it if you are after max possible frames.

Edit: Should add that with my 5800X and 3600 CL16 RAM it is good for 140+ in most places so might be an easier upgrade for the 144Hz screen you have.
