I have a feeling that Arma3 launcher is wrecking my drive every time I start it. Having lots of mods and lots of those beeing from Steam Workshop will cause a launcher to have huge startup delay, and during that time delay your HDD/SSD activity is skyrocketing causing entire system to be sluggish.

What I am suggesting is that, since not all would support this, option is added to the launcher to disable auto check for updates/signatures, and if so another button is added to do so manually. If not make this the default launcher behaviour.

As a plus I dont think its just updates that causes the delay but I have no way of checking what launcher is actually doing on startup. I can only assume that it is checking for signatures and whatnot on every launch. If so Id rather have this set to manual.

This can be fine for someone starting launcher once a day to hop in MP and play some, but for someone doing other 99 things in Arma3 this is a problem.
