After the latest round of modpack updates I've started experiencing unusual frame drops in ARMA. Standing without moving my FPS jump from between 130 and the high 50s for no apparent reason (maybe this is normal, I haven't paid much attention to FPS since I got my latest rig since it's always been fine).
I've read through 8 pages of results from searching "FPS" here and can't find any suggestions that seem applicable. I've got the latest drivers for my graphics card and I verified the ARMA files. Suggestions welcome.
EDIT to add: It seems to be related to Teamspeak - with no TS running my FPS is fine, as soon as I activate it, FPS starts bouncing all over the place.
I've deleted and reinstalled TS and TFAR - no joy.
EDIT: In TS Addons I have task_force_radio_pipe throwing an error "Plugin failed to load: Failed to open plugin.: 0 (minimum: 21, current: 22)" in red. Reinstalling didn't fix.
