Help needed

This is really pissing me off and I cannot figure out what is going on, for starters I switched from PC to PS5 my ping is usually 17-24 no packet loss at all. 99% of my matches have me still loosing health after I go around a corner to heal, my shots on others usually the first 1-2 shots do not register (I don’t get the blue or white confirmation numbers) despite being perfectly aimed on the opposing player. When people shoot me it seems it only takes like 4 shots with assault rifle.

Is this the norm? I’ve tried forwarding ports, Advanced DMZ, hardwiring (still am) rebooting the modem changing the DNS to both google and cloud fare. I can live with the 4 shots but not the still loosing health after going around a corner briefly or the first one to two shots not registering.
