Does this happen right away? Like you turn your pc on,log into conan and enimies are bouncing around?
Is your pc cleaned out? Maybe graphics card or cpu is over heating and needs a blow out?
Sounds like you tried alot of things so to me it sounds like something on your end is messing up.Run a virus scan,update windows, update or reinstall graphics driver,make sure all fans are running in the pc…hope this helps.
