I'm really hoping somebody has encountered this before and knows what could possibly be causing it. I added quite a few house mods/city mods since noticing this problem but since then I have un-installed most of them completely via OBMM. I would love to hear that it is not possible for something like this to be caused by a mod, that would put me at great ease. I've spent so much time modding Oblivion over-time for a mod to cause this would be quite crappy. I'm just hoping maybe it is a driver error or something, I posted in the Mods section cause the people here just seem a lot more knowledgeable about the game and if it was caused by a Mod I don't think anyone else would know that in the other forums. So i'm crossing my fingers here!
Here's a .gif showing the problem. It is when I move the camera to certain angles/positions the foliage on the trees will just vanish (although a few blackish dots are visible if you look closely.) I have also noticed on the foliage, on a few bushes when moving the camera in the same way (just seems to be certain random positions,) I got green boxes around the leaves on the bush. Seems textures aren't loading properly somehow? Don't see how that could have changed.. but here is the .gif please tell me what you think.
Oh, I'm using an ATI Radeon 5970HD with the Catalyst 10.4 drivers.
