Log attached. Thought it might be mod-related so I ran a scenario without any apart from SRS. Things tried so far: integrity check, updated NVIDIA driver, windows is current, DCS is current. In the past I've unlocked the core, tailored DCS settings to my machine, etc. Been a while since I've had crash to desktop. Logs mention lots of "voice chat log" related things - even single player. Multiplayer lags far more than it used to.
