Thanks Od1n to have clarify this to me, that's exactly what i thought about the new editing system.
Sure it's a little bit inconvenient to not have access to our editings in real time to test it (PC management only), but if the APEX 1000hz do the job as it supposed to do, i will not have to spend a lot of time in curve's editing ect.. like actually with the XIM4.
Cause actually i can't find the perfect settings with XIM4, because of "bubble AA shjt', so i can have fine micro-movements + rapid turns but bad bubble AA, or can have good bubble AA + rapid turns but with no more micro-mouvements, so i have always to deal with XIM4.
Before XIM4 i used MAXaim (Cronusmax), but XIM4 is far better and was a GREAT updated to me, i wish now APEX will be my next GREAT updated to achieve my Dreams to come true.
Can't wait to test it !!

As i understand the new APEX, with 1000hz to compare with 125hz, we'll have to multiply our sensivity by 8 to achieve the same sens in-game (if we use 1000hz). Because my Razer is only 8000dpi max, are the "over 100" sensivity on APEX a limit to not pass as i read before for the XIM4, or will we be able to go over the 100 sens in xim without in-game's inconvenients?
