ok folks i had many latency issues in 8.1 running a dj software causing spikes to 100% on cpu rendering my laptop useless i had all acer drivers and all windows updates. i paid acer premium to try and help no help there i tried acer no help there. anyone facing these issues when using traktor. ignore that acer say they dont support this model and upgrade to windows 10 with only important windows updates. your laptop will run as it intended to not how acer wants it to with their poor drivers.make sure you format the drive and get rid of them nasty recovery partitions too theyre poo. took me weeks to sus out it was acers crappy drivers making my system run like poo any questions fire away
