In response to post #116454623. #116456368 is also a reply to the same post.
Fair enough.
Although, it maybe worth taking a look at the comment (with links) from user, "redflamingolingo" in that LOD Restored thread.
They had uploaded two .zip files containing their modified .csvs. After loading those up to test, they are definitely hard hitting. I can't say for sure which is the most taxing among those tweaks, but I lose 12 or so frames in some areas.
One area that was used for testing was in front of the Dectus Lift, while descending the stairway (on my rig) I lost nearly 20 frames. Likely the grass modifications, but I can't say for sure.
I'm on a 3080 Ti + 9900K with 32GB of DDR4 @ 3840x1600. So seeing those types of drops is surprising, even for adjustments to LOD.
