[SOLVED] Ryzen 7 5700x questions about SMT and PBO

[Dropment]

I most play Call of Dute MW2 on my pc and i disabled smt and enabled PBO. Does mw2 rely on multithreaded cores?

is this safe more my cpu to always be on this?

You might have some misconception about cores and threads.
Cores are physical parts of CPU but threads are part of microcode. practically software built into CPU.
Loosely speaking. if a CPU has 2 threads per core it actually uses empty/idle times when a core is waiting for an input for a request to run a task. OS actually "thinks" that it's another core and uses it accordingly.
In some cases a program/game could run a bit better with threads disabled but that's only because of lesser load on CPU and actual core number is sufficient.

SMT disables threads not cores, game will still use cores.
PBO only increases available power to CPU which not necessarily need it. Doesn't make any effect unless very heavy load.

would it be useful to have smt on ?

You tried it both ways, I mean you did disable SMT after having it enabled, you tell us if you get higher FPS or not.

i have tried both and it does give more fps but the mw2 bench mark says the cpu is more of a bottleneck in 1080p

Do you care more about the benchmark or more about how the game plays?
Yeas, if you turn off the SMT the CPU will run at a higher percentage and so it will look like it is a higher bottleneck, but so what?! If the game plays better it plays better.
