My game uses Streaming enabled and whenever you are driving throughout the map and a chunk loads in the FPS drops from 60+ FPS to under 20-30 and this varies depending on the players device.
The map has about 8 million triangles, which I believe is a good amount for the size of the map.
I am looking to see if anyone else has this issue or if they had the issue and how they came around to fixing it.,
Thanks
