Every 15-60 seconds, the game's frames per second drop to an unplayable level. Tabbing out/back in fixes the issue every time, but it's still extremely frustrating. This is on version 1.4.23 (first version I've played, so can't say if it's a version specific problem.) I don't have the same problem with single-player ArmA, so I know it's not a graphical issue. And it happens regardless of server, so I don't *think* it's connection. Specs: Windows 7/4gb RAM/intel M430 @2.27Ghz/Geforce GTS 360M/All drivers up to date
