Can someone help with Lossless Scaling settings for Torchlight II at 2880x1800 resolution?

My native resolution is 2880x1800, but my APU 7840u, isn't powerful enough to play this game native at 120 fps.

I do own Lossless Scaling on Steam, what settings would be best to get as close to native as possible, but able to maintain 120 fps?

I really don't understand any of these settings... so if someone could just tell me, it would be helpful.

torchlight 1 ran at native resolution and no fps loss, so I didn't need this software before.

I am not sure, this is what CPU-Z says, it's a laptop with 16gb of ram embedded ram modules. HP Ryzen 7840u 2880x1800 120hz OLED laptop 14" in size

I know how to scale, like the process of "hit scale" then within 4 seconds click on the app you want to scale. Problem is I just don't know what settings to use. Set in-game resolution to 1920x1200, then what scale settings to use?
