Can I restoring the initial settings?

When I first installed 2020, I could swear it flashed a message about detecting optimal settings or something. I never changed those initial settings but noted that it was definitely custom. Some things were high, some med, some low. etc so it wasn’t a canned preset. And it worked very very well.

Then I launched the game with GeForce Experience…which changed EVERYTHING, including resolution, most items on low. Looked terrible (and really wasn’t all that much faster.

In game I did a reset-settings, but that just loaded the High preset, which is too high for my hardware.

I just want to get back to that perfect mix I had. Is there anyway to ask the sim to do that initial detection thing again?
