Even slower now laggy playhead 23.5

Stop your empty words. Yes, we have troubles and it is Adobe which brings raw, untested product. Problems with multicamera, monitor buttons issue, exporting issues and etc. What kind of computer I need to use to avoid this headache?

This is where people go to communicate with their peers. Most people  that come here are for their problems. Adobe lets everyone run what they brung. They are not mandating the latest hardware, etc. I think it's great that way. You didn't say how many processes you have running. How old is your Windows installation?

for what i see is that a lot of people have my problem. 

It's beed for couple of years no fix now, no fix in the future. Typical adobe. 

I guess that's it? Like I said, many of us are not having that issue.

Here's a screenshot of my fairly optimized machinel. I work hard to keep the processes down, as each one takes a small slice of processort time, each clock tic.

Done that, reinstalled premiere couple of times, same thing

Hold down shift as you click to start PP, you'll get options...

Alot of us are not having those problems, so what have you done to try and fix that on your end?

Reset the preferences back to default? Clear the cache, etc...

Well your comment didn't feel very positive. 

gpu 3090

cpu 5950x

ram 128

and i got specific. Everything laggs what else do you want me to say more? Every option that i make laggs. Multicam laggs, nesting laggs, single footage lagss, slow motiong laggs, fast motion laggs, 1080p laggs, normal footage laggs. changes in lumetri laggs, 

You didn't mention your hardware except for the 980pro or such. What's your hardware like, you didn't even say mac or pc. Rant if you like but if you want help you need to get specific. And you can still download version 22, and previous versions of 23.

What to optimize more? Quantum computers are still in development.
