God dammit.
If you went to the topic I linked you, you would see you can run shaders on Max and get 70FPS. In this topic I said you could get a stable 60FPS on medium, no matter how many bricks there are. But again, taking a look at the link I posted earlier, you can run them on max. It just depends on how many bricks there are.
I'm guessing you can get above 30FPS on max, I'm not 100% sure because 60FPS is smoother, so I keep it at medium and just about any build doesn't cause it to dip below. But there is no doubt that you can get a good performance on max settings. It just depends on how smooth of a framerate you want.
