Halo Wars 2 campaign

Why is the campaign not running properly?
It is really annoying how often the game freezes, why does that happen, not even playing online…
P.s. I’m having the game cd, no download

I’ve had 1 total freeze but more stuttering from time to time for no apparent reason .

With my spec of computer is well over th recommended

Level 11 always freezes while I’m trying to destroy the base ( on easy mode), just the background music keeps on playing. I’m trying to do this level for the 3rd time right now.
Maybe people who are not getting it done to create a campaign that runs fluently , should not produce games anymore…

I’m very upset how long it takes to load the campaign (as I recently wrote , I own the game on CD !)
