I use DX11. This game has been pretty stable for me.
I was able to run four clients at ultra settings at the same time and barely a hiccup. It’s not like I have a powerful system also.
That is odd I have a system that was high end 3-4 years ago, and can still run games like Cyberpunk 2077 on ultra with no bugs or glitches. I too run the game on DX11 and for the most part runs smooth. But then when it gets to the 30-60 minute mark it begins to lag and stutter, especially during cutscenes. I know the game is in Early Access so I'm not really stressing it. I just posted the problem here to see if anyone else has had the same experience.
