In an unusual move, SimBin has released the playable press demo of GTR, their upcoming FIA GT racing simulator, for the public. Awkwardly, the demo is still protected by a password though, so you'll need to enter "GTR_Press_Demo" during installation. The demo contains the Spa track, drivable in the Lister Storm and Morgan Aero 8 cars, but as a work-in-progress release it doesn't offer the polish expected from an official public demo.
