If the changes in the update are related to an already implemented "feature" then you may see an improvement, however if there are new features in the update that ED hasn't yet implemented then DCS is not going to be able to take advantage of them.
I think this is what @Glide is saying, and he's right.
If you see an improvement then that's great. I personally didn't BUT I'm not using DLSS only DLAA (which I saw no improvement in) and settled back on TAA.
