You’r site is runing very fast and i don’t know how it is interpreted like this by the webpage test.
But when you look at it, it says that the first byte load time (which takes 2,5 sec) is related to this URL: https://www.lost-in-games.de/new-3ds-xl-im-snes-look-erscheint-naechsten-monat-japan/
From the console it looks like there’s a call to this page on your homepage load and that’s the first resource your site gets, before anything, even any js or css files.
Regardigng the PVC, it takes circa 150 miliseconds, and it is asynchrounous, does not influence your site load.
I think it would require a deep look into your site to find out what really happens, but this is obviously out of the support scope.
