He's testing the update maybe max 1 hour long for days. If he starts to check grammar for that i can guarantee any stutter person can get read out whole game faster than him reading the update.
He's having so called crashes never doing a thing about it. I'm pretty sure he's lying about it. If i was having these problems and im depending on this game i should change config or change some parts or even install new os. But he's just ignoring and praying it to go away.
