Well, why would diablo release 32bit Client that allowes you to use 1920*1080 144hz and then
release better version wich is 64bit and then you are not allowed to choose your optimal
resolution... every single game on market even small small games can offer you 1920*1080 144hz
accept blizzard it seems.
And if you dont know what HERTZ does to your monitor.. just go desktop right click go to your monitor resolutions advanced settings and change your monitors HZ to the lowest and move your mouse around...your gona feel big difference on smoothness
of your monitor, no matter what you do if you are allowed to use your monitors optimal HZ.
