I will just copy paste my post from the other thread about the same topic.
LA Noir on PC. I can run crysis on high at 1920x1080 at a nice 30 FPS and tons of other high end "power" games with zero problems, but I can't even run LA noir at 800x600 with everything turned off. It's literally a slide show it runs so terribly. I'm well and beyond the minimum specs as well, but it's literally unplayable. Between that and GTA 4 being in basically the same boat I will never buy a Rockstar game on PC again.
Also, Dragon Age 2. That game made me so dam sad after how much I loved Origins.
