Is it my internet or my ps5?

My husband just downloaded the game, had never heard of it till caseoh began playing.

However, we’ve done everything we can to fix this, but there still seems to be a lag. I’ve restarted both my modem and router, cleared game data, cleared cache, restarted the PS5, switch HDMI cords and I’m still having lag/loading issues.

I’m curious if there’s any settings I can switch to help it not lag? If it helps, my WiFi is 1000mbps (I’m clueless with this stuff lol)
