I have been watching multiple benchmarks and have seen that there is a noticeable FPS drop this year.
I have also been doing some benchmarking myself and see similar results.

Anyone else noticing this crap?
COD just continues to become more and more unoptimized every year.

Back in MW3 I had a 4070 Ti and got 400 FPS, and now we have 5080–5090 cards and are getting nowhere near what we should be getting.

I guess games are just not as optimized as they used to be.
