BigTinz: Folks are just mis-remembering, or trolling.
There is ZERO documented proof of the grass not rotating, and 10+ years of video showing the grass rotating.
I was even fooled for a bit, but I've come to accept that the grass was always supposed to rotate, and does.
Please look at this video (I timed it)
https://youtu.be/mebA1iXuZEY?t=468 The guy look around , and if you look at the grass it may rotate on self but at a distance it's not visible.
Now, if I do that in my game the whole thing start spinning in a very unnatural way. I know game of that era use that technique, but not all the grass spin, usually some grass around you.
The fact is, in this video it's how it's supposed to be, and my game is not reacting like that. You could see all the grass going all over the place with that kind of view.
And please dont say people are trolling because they have an issue you don't know of
edit :I think I found the issue and why it causes some confusions.
The grass is indeed suposed to rotate in the original game but at the certain point, the game will load LOD grass that are not supposed to rotate (or at a very slow pace). I don't know how but my far cry 2 installs were broken surely because even when uninstalling the game some files would remains.
What happen to me I think is that for some reason the grass far away was rotating as fast as the grass at my feet where the LOD should have a much slower rotating speed (that's why it was shocking).
I managed to fixed it by making sure I uninstal the game, delete every far cry 2 files on my computer, re install my nvidia driver with physx and audio driver + geforce experience. Then the only mod that I used is the farcry2 launcher multi fix.
