Phoronix has posted a review on the Linux Port of X2 - The Threat

Announced last week by Linux Game Publishing was word that Egosoft's X2 The Threat had finally went gold with its Linux port. Today at Phoronix, we are performing a GPU showdown with a handful of popular graphics cards to see what reigns supreme as well as looking at what will be required to appropriately run the game with Linux. We have taken six PCI Express cards from both ATI and NVIDIA and now have our X2 The Threat results for your viewing pleasure.
