How large can the skybox get? I'm working on a map set dockside, and the ocean side needs a fairly long sightline. As a result my 3d skybox is about 3000 HU across by 2000 deep. Is that safe or is it pushing it?

(My own computer is extremely fast and it isn't slowing down a bit but I don't want to create a map that's unplayable on slower systems)
