I hold ~60 fps regularly, but for some reason I can't look down in certain areas, and the new feast arena is one of them. It drops down to 5 fps or so. Yes, 5, that is not a typo. One thing the areas seem have in common is water. Do you think this is an issue with either my CPU/graphics card? I've updated all my drivers, and ingame visual settings don't seem to affect the situation at all.

I used to be able to ignore this issue, but with the release of The Feast I often point my camera down to look over the barriers in the middle of the map. The other members of my 4v4 premade have noticed no change in fps when looking down so I'm thinking it might be an hardware issue.
