Expected performances for PCVR

Hello, I've recently got my hands on a Pico 4 and even if I need to strengthen my "VR legs" I'd also like to enjoy the world of PCVR.

My PC specs are :

• intel i7-9700k (not overclocked)
• nvidia RTX 2070 (not the SUPER one)
• 32Gb of DDR4 Ram
• games can be installed on a m2 drive

I have not yet bought anything specifically for the Pico PCVR so I have only a normal wifi (5GHz) from my ISP. I can have a wired USB connection if that's better than wireless, I already have long USB cables.

What can I expect in terms of performances. I know the hardware is not current to of the shelf but its otherwise handling itself quite well.

I'd like to know if that can get me a good experience (number of fps and quality) already?

If not, would I be more constrained in what games I could play or just having to adjust settings? What settings have more effect in bettering the experience? Lowering resolution (4k --> 2k / 1080p) or lowering quality (ultra --> medium)

If i go the upgrade route, is it purely a display thing meaning just upgrading the GPU or would it also need a CPU upgrade?

Thanks in advance!
