I believe something is wrong with this one, I don't seem to be able to get the sens right (88.6314cm @ 360°; 16:9; 103 HFOV; 1100 DPI). Using 23.76 FOV Offset (103 Hdeg 16:9). If I use 3 WPS (my windows settings), it's way too fast. If I use 10 (default), it's way too slow. If I use 3 WPS and leave FOV at default in the calculator, it's still too fast. Any idea what the matter is with this one?
