I got a great upgrade with the 1.7 patch! My frame rates are up about 15%-30% and it just seems a lot smoother moving around (getting nearly 40 fps in the dense part of IF). Textures also look sharper. This is with a stock dual 2.0 G5 and Radeon 9600 Pro/64, 1.5 GB RAM, 128x960 & medium settings. The weird thing is I can't find anything about Mac improvements in the patch notes but I don't think I'm imagining it. Anyone else notice a change?
