Were you using Blastcore Mod while you encountered that problem?

This also happens when the Blackfoot fires. No mods at all.

I made some testing, and I can confirm that issue. It applies to the Blackfoot,as mentioned above, and in addtion to the Jets machinegun and the AA.

No mods/addons launched, just vanilla game.

This is actually pretty bad, I can't create levels with Blackfoots or any AA sometimes. It's also the main reason for bad multiplayer frames for me. Hope they can fix this.

I'm fairly sure this is related to the way sounds are handled. Try dropping the available sound channels in options menu, though this'll probably cut some sounds out. Most integrated soundcards can't handle too many concurrent sounds.

I tried while playing as the gunner of a blackfoot and having it as AI only. Even with the sound samples lowered, went from 128 to 64, I still had problems with the game slowing down. The game actually crashed with the all to common : DX11 error : buffer Map failed : DXGI_ERROR_DEVICE_REMOVED
DX11 - device removed - reason: DXGI_ERROR_DRIVER_INTERNAL_ERROR
after firing the 20mm gun for about 30 seconds without stopping.
