It doesn’t matter which model your Bloody mouse is, exactly in this way the macros are installed on all a4tech Bloody mice (V3M, V4M, V5M, V8M, V7M, T50, T60, T70, N50, A60, A70, A90, A91, R30, R70, R80, RT50, RT70, ML160, ZL50, TL50, TL60, TL70, TL80, TL90, AL90, P81, P85, P93, etc.).
How we will know correct sensivity ? for 2x ?
we should try in game and find ?
Depends on the game. For games / weapons with linear dependence on all axes, the sensitivity for different scopes is indicated. If it is not specified, then it is impossible to transfer the macro to other multiplicities without loss of precision.
