Hello. After a lot of tests I have seen that it is running really good with a high framerate. But if the framerate is for example only 30 it is not that smooth anymore. Of course, 30 fps is only the half of 60, that's true. But if you look at tripe A games, they have also no problem with a smooth camera movement at 30 fps. What is their secret? I know, Gamestudio is using the windows mouse driver, as far as I know, but maybe their is another trick, another algorithm?
