I was playing a MPmission online with friends when I saw this issue.
Plusminus 1000 meter north of Camp Rogain there is a huge rock formation.
A little bit to the west. I do not have the exact coordinates.
I was walking below of the rock formation when I saw one of the big rocks completely disappear.
When standing still and looking a bit to the left then the rock was gone.. When you look a bit to the right, it is there again.
{F19399} {F19400} {F19401} {F19402}
I own an older PC.
It's not state of the art.
It works fine though and it should work fine, but I'm sure this is not the problem.
My fellow teammates saw the same and they do have a brand new, state of the art machines.
This screenshot I attached is from when looking to the left. I have also screenshots while I look to the right, but I can only attach one picture.
Later I will try to get back to the place to find the exact coordinates
This also happens while running past the rocks on the hill immediately south of Agia Marina, they're not as big as the rocks in your picture but it's still noticeable - And weird... Why are they doing that?
I also found out that on 048086, there is also a big rock and you can walk in it from the north side. From south (above) you are walking to a wall but when you "v" you get stuck in the rock. I've added a screenshot as proof. I found this by mistake when trying to find the coords for the original problem.
