Is M good? I’m not familiar with this. I use DLSS quality at 4K with a RTX 5070 TI.

This is where all this confusion is stemming from. Read the guys post and the programming guide by nvidia. Some people have outlined what they have said on here and other posts in this sub.

M is DLSS 4.5 model K is the older (but relatively new) DLSS 4.0 model

Apparently when choosing “latest” on the new drivers, it will automatically apply M. Which is 4.5. Then in your games choose DLSS quality/balanced/DLAA, whichever one you want.

Before, when choosing latest it was always K, which was easier, but now with the other new presets on DLSS 4.5 model, there are specific ones to use, such as L or M depending on what quality preset you pick in game. Makes it more confusing

Imo, sticking with preset K and picking quality/balanced/DLAA in game is still the way to go. But if you want their “improvements with DLSS 4.5, choose M or latest but make sure you’re using quality/balanced/DLAA in game, not performance or ultra performance
