Which DLSS.DLL version to use with FS2020?

Hi. Iv’e got a 3060 Ti, and I wonder whats best: Using the DLSS.DLL (2.4…something?) or a newer version? Is it worth getting the absolutely latest version (3.5 ?) with my card, or is that for 4000-series?

With the version that comes with FS, theres still a bunch of graphic issues with water, fine textures etc - or was pre SU13. Are these fixed maybe?

In a word no. I have a 4070ti and the issues still remain.
