The 5060Ti 8GB needs to be treated as the type of card it is, a low-end GPU ideally meant for 1080p gaming. This means you keep settings realistic that it can handle so it's not swapping textures in a saturated VRAM situation that tanks the performance. The screens you posted do not do this, they're simply trying to make the card work hard at something it clearly cannot support like the 16GB variant.
Browsing through the HWU video it would have been better to post images of the medium settings tested to show that the card is indeed capable of what it's designed for, low-end gaming by today's standards. Sadly, most of the games tested were always tested at high/max settings with and without RT that showed the card unable to perform; the exact way we'd expect it to fail with only 8GB.

These screen grabs show the card is capable of playing these games fairly well when set to acceptable setting levels and resolution. Anyone that gets this card or even the 16GB version and expect to max out settings and have everything playable at quality performance levels, you're sadly mistaken and need to rethink what you're doing.
I'm not supporting this 8GB card and saying it's a good value (it's clearly not and I'm not saying the 16GB version is a good value because I don't feel that it is), but what I am saying is that the card needs to be treated exactly as to what it is; a low-end, overpriced, gaming card not meant for maxing out settings over 1080p....and even then that's a bit of a stretch to do with some games.
