The day has come ! Batman Arkham City is the first game that made my computer show its limits. Like with every other game, I maxxed everything and assumed it would run fine, but I get an average of 18fps. I lowered some stuff in the parameters and still only gets an average of 30fps with major framerate fallings on some scenes of the performance test. My computer : i7 2600k nVidia 570GTX 8GB Ram Anybody knows what will most significantly increase the fluidity without making the game too ugly ?
