Arma is on an intel SSD. Since the last update I have been experiencing "microstutter" where the game freezes every two seconds. It will do this steady - same intervals in all game types, with and without mods, on all maps. It is also visible in the background splash screen of the menus, etc. Present if GPUs are running SLI or not.
UPDATE:
Second issue involves TeamSpeak 3. Upon turning on Teamspeak 3, the game drops to 1-4FPS in all game modes and is unplayable. Problem persists until PC is rebooted.
