Hi there, since Tanoa's release I noticed some quite jarring problems with grass LOD's due to the new system for phasing the LOD changes which only was a big problem on Tanoa for me and pretty much everyone else. E.g. the grass would change in very close proximity to you in a very noticeable manner.
After a recent driver update on my Nvidia card it seems this LOD problem has become even worse for me, but now on terrains like Altis as can be seen in the video linked below: https://www.youtube.com/watch?v=OUI8c94eYNI
I believe this is not intended.
