My question is simple, did GOG patch this game to use more memory? I recently bought and installed it and it does seem to run a bit better than the ORigin client version which would crash occasionally, slow down, start stuttering, take longer to load after a little bit of playing, perhaps they never patched that version for it's memory leak or something? DID GOG patch this one, it came with a patch but I can't find any info on what the patch was. just wondering but I also saw some options in the main menu as well for full screen mode and I don't remember that option being in the origin client version either so maybe that helps performance?

There's a sticky concerning the changes:

Looks like they forked it away from the official version so not to call out to Origin.

ah. yea I spoke too soon. this version also has performance issues. I searched steam forums as well, found a 4gb patcher for the exe but I don't think that's really helping anyways. it might be idk, does seem to take a little longer now to start running into issues such as slowdowns/longer loading times and stuttering I mentioned.
