My review on Steam Sometimes certain people meet, and create magic Lucas and his creation ILM - Starwars Bonham, Page ,Plant and Jones - Led Zeppelin Zimmer and Nolan - The Dark Knight Reiza Studios - rFactor mods , Gamestock Car Extreme, Automobilista using the rfactor engine And now the magic continues using the Madness engine. Ignoring its Pcars roots, the engine is very capable and is still one of the most modern made for commercial games development. Slightly Mad Studios built it well. Its the best VR racing engine to date. It models temperature bleed from hot tyres into brake discs, tyre wall flex, tyre damage, advanced suspension dynamics, under-body vortex and suction know as ground effect are all built into its code, but it was at the hands of a developer that was more interested in selling its engine to others so they could focus on console games. We now have that developer. Reiza turned an ageing rfactor engine into one of the best sims ever made, with Automobilista. Now they are using a 64bit 600Mhz fully VR capable, unique SETA tyre model sim engine. Hold on to your seats because your sim hardware is in for a treat, as are you. edit: i put 600Mhz because i was sure that pcars 2 was running at that rate on PC but it can (in a powerful sim rig) run up to 2000Mhz
