Ever since Arma 2, across 3 different PC's, from XP to W10, Nvidia and Radeon, i've been cursed with the problem where all onscreen action and sound freezes for x seconds and then resumes. Whilst the freeze is occurring, the player avatar is still merrily doing whatever he was doing before the freeze - which is a problem when you are driving a car, or in combat.
I've heard many reasons for this - network latency log jam, GFX RAM being flushed, game cache being flushed, CPU bottleneck, conflicts between legacy DX code in Arma's engine and DX9/DX10/DX10.1/DX11, and on and on.
That it still occurs in the Enfusion engine is amazing !
DayZ runs beautifully, except for this ancient legacy follow over from the Arma series.
