I'm not sure why you are showing me this, I'm not acousitc like you guys.
I like only like actually cool stuff, like fast cars, rockets, construction, giant machines. Police sirens are far out on the spectrum.
this might be a long shot, but how about a button in the f1 menu and instead of "disable TV" you can also select "disable TV screen" and it will save performance?
I just tested. It does still work, but its very buggy, stops working after couple seconds or meter or if someone moves fast. Def. much less reliable than tracking items, they used to work similarily well.
