New gaming mice tend to be released with high DPI counts, but how much DPI is really needed to play games? Higher DPI obviously seems better. Like the steering wheel in a car you want continuous and smooth control over turning. The difference is that game graphics is made up of pixels, rather than the real world which has much more detail. At some point, having more DPI becomes unnecessary because the actual bottleneck is the screen. But how much DPI is enough?
I will use the example of playing an FPS game. If you are playing on a screen resolution of 1024 by 768 pixels, then we can roughly work out the number of pixels in a full horizontal rotation of 360 degrees. We multiply the number of pixels across the screen by 4 (since each screen is about 90 degrees viewing angle).
Pixels in 360 degrees = 1024 * 4 = 4096
Now we need to work out how far we want to move the mouse for a full rotation of 360 degrees. This distance changes depending on the gamer, because changing the game sensitivity changes how far you need to move the mouse for the same effect. By dividing the total number of pixels by the total distance (in inches), we get a rough idea of how much DPI is useful.
High Sens: 360 degrees in 0.1 m (4"), roughly 1000 DPI needed
Medium Sens: 360 degrees in 0.25 m (10"), roughly 400 DPI needed
Low Sens: 360 degrees in 0.50 m (20"), roughly 200 DPI needed
While 3D games don't need you to turn a whole pixel before the screen changes, this is a sensible way to work out when more DPI resolution stops being useful. What we find is that standard 400 DPI mice are ok if you have a low sensitivity, but there are times when more DPI can improve the game. If you have a High Sens and a huge 2560 x 1600 panel to play on, our formula says that our ideal mouse resolution is a whopping 2500 DPI!"
Ergó high senshez (100mm / 360fok), 1600p-ben is elég a 2500dpi. Bőven. Nekem, aki low senses (450mm/360fok), 1024*768 ban (amúgy 800x600ban/640x480ban csgozom), a 200dpi is BŐVEN ELÉG LENNE.
