Almost all flight sims suck when they come out...
Especially when a new 3d system is in it. Remember Rof when it came out, Il-2 when it came out (on my system anyway...).
Dcs A10c the first few days, I had too many problems to count. Even though Dcs already had it's graphic system well tested.
So really we are beta testing something that NEEDS hundreds of beta testers to be really get debugged. The first videos we saw were from FPS kiddies with old machines who had not patched the game. It will get immensely better like all those sims did (except WoP).
PS: There is relationship between the complexity of a software and the number of beta testers that you will need to clean it. A little like he number of people you need is a survey to get at a certain projected precision of the results. There is a whole field dedicated to that kind of thing, lt's called software engineering, and large companies with a lot of budget can actually apply it's vey effective methodology. But in real life you don't have those kinds of resources unless you work for Boeng or the pentagon...
Breathe through your nose...It WILL get better.
