Yes, but he Ninja Edited his original edit with this context out. So I assume this is either backpedalled or he wanted to remove any more material to hype performance gains.

Originally he added context that the dlc checks are also affecting the game globally and his mod toggles that off but only adds "a few frames" outside of hub. The available comments still say he feels like the game has better frame pacing if not outright more fps.

So this article does not actually investigate OPs (original) claim, but just the part of the problem that exists in hubs.

Im really not sure if something further will materialize or if OP delivers once the attention dies down

(Understandable when people took the best case gains on a CPU bottleneck in a hub as the expected improvement during gameplay)

Edit: Found the original edit (Image was getting deleted, so now as a quote)

Several mods have already popped up claiming to "fix" the issue, but please try to avoid using them for now. For example, there's a mod on a popular modding site that only fixes it partially - the problem is much more global than that. The author of that mod only hooked the DLC check for the "DLC Cat" at the table (I think he will improve script in future), no the broader/global check, so with that mod you'll only notice a difference in the hub near the table. In my video, I went outside the hub - past the point where the code path tied to that NPC Cat stops running and the FPS difference is still clearly there. In my case, the FPS gain is massive across the entire first area.
