Are they? I don't remember MPs, Alan Wake, Quantum Break and Control having very significant bugs.
This boss is so bugged I lost my patience and just did the "accesibility one shot setting" to kill it cause it never stopped crashing:
Also on Control, I gave up trying to get 100% even though I felt like trying (I almost never do but I try for some games I like a lot), but the Jukebox quest was bugged since I completed it and the game never marked it as completed, it's a bug that even affected the PS4 version and the "solution" is to start over again to see if it doesn't happen in that new save... Damn.
In Quantum Break, I was getting shadows and sky flickering when moving the camera if I set the resolution over 1440p, even if I could run it easily at 1800p or even 4K, never understood wtf was going on.
And all of them are heavy on GPU. Even Alan Wake was one of the less performant games I played back in the day on my PC.
it's a shame because they are some of the best looking games so playing them on PC should be a given.
