That shows your CPU (which is a little low for PCSX2) but it doesn't tell us your graphics card which can also have a fairly big effect on speed as well.
PS2 emulation is very very CPU dependant... Requiring, in the more extreme cases, a 4ghz or higher CPU (though in general, 3+ghz is where you need to be) and at least a mid-range DX10-11 video card.
use latest official beta 0.9.7 (see the downloads section)
your cpu is average for pcsx2, some games will be slow.
and what about your GPU ? (because DBT3 is quite GPU demanding)
CPU : AMD Ryzen 7 3800X
Mobo : Asus PRIME B450-PLUS
GPU : NVIDIA GeForce RTX 3070
RAM : 16 Go
