Anand's article. I find it notable that all the noticeable changes were 64-bit independent. Note that the performance changes were without the graphics improvement - the IQ improvement's performance hit is not being offset by 64-bit. Perhaps this is a bad omen for 64-bit gaming - meager improvement over 32-bit even when the OS and the game are both 64-bit. Or maybe a bad compile, whereas [maybe] games designed in 64-bit with newer instruction sets will perform better? Or perhaps it's good - a fairly major game released in 64-bit.
