The base version of the game does not perform at all on modern hardware. I have a Xeon E3 1231-v3, 32GB RAM, and GTX 1060 6GB and the frame rate will slowly drop to slide show speeds. There is a bug in the base game that causes performance issues on PCs with more than 2GB of RAM, fortunately, the Star Wars support site has a patch for this issue called EAW_RAM_MPLobby_update. After installing the patch the game was much smoother. Wish GOG would include that patch with the download so I didn't have to hunt it down.
