if you get an error Launching the game its the direct x
on the launcher in the bottom right there is an ( Auto ) tab.
click it and choose 11 or 12x depending on what you have… 
So far the launch of this update is going way more smoother than the last two, I’m actually able to play the game instead of it being a lagging crash-happy mess, and have not noticed any wonk yet. No Orbital Station 2.0 another map running at 9fps for no given reason boogaloo
Trying to find something good to say about it…it’s neat to see more parts of a build a teammate is using when spectating people after death, even if I usually just switch off to a web browser and resume watching a video and so on instead of paying any attention how the rest of the match goes after I do a die
today (an hour ago lol) I was kicked in CC loading screen dozens of times. Usually it happens once max every time I load \ open the game.
(Plus alot of Lag in the Brawl, but you don’t like it)
