Ok, all the more reason not to use AA then (SSAA even more taxing than MSAA) I think the originals had AAA as well but quite frankly I couldn't tell if any form of AA was used when AAA was selected. Or maybe it only kicked in with very high settings. Would explain the perf. drop maybe. Played 2033 and LL with ingame set to AAA, 2033 @ High, LL @ V.High and Vsync + SMAA/FXAA forced via RadeonPro. Naturally with Nvidia you can just force Vsync+FXAA with driver.
