At the moment I'm using DA at 450 dpi, and I moved from 1024x768 (4:3) to 1280x800 (16:10) which I use for quite some time now.

But would I benefit for having higher mouse dpi settings considering Im playing on kinda higher res with only 450 dpi ?

If I were to play on 1680 x 1050 how much better would be to use 1800 dpi instead of only 450 dpi (ofc even if I use 1800 dpi I would just quarter my in-game sens, so my real sens stays the same) ?

In short, whats the optimal setting between mouse dpi and monitor resolution ?
