If they're consistent with each other it might be a graphics performance issue, if not you can be sure there's some other subsystem that does background processing and needs to finish its stuff. | ||
Move the view around, do you get stutters? If you do, then there's some pressure on your video card's RAM. As it needs to load the new geometry and textures that come into view, it might not have enough space left, so it might need to offload the "old" ones. Even like this framerate should stabilise once you stop moving the view around, or once the rate of movement is slow enough so that the video card can keep up. | Move the view around, do you get stutters?
