"Improved visuals" that are "similar to the benchmark" ?
Sounds to me like they had one version for benchmarking, but sold an inferior one and are now updating it to previously-existing performance.
In other words, they sold a dumbed-down version in order to make themselves look good by publishing a patch that made it look like it was supposed to from the beginning.
Can't say I like that way of doing business.
But I don't have CoJ anyway, and now, I won't buy it.
