It's the whole dynamic nature of the game. Nothing's baked, nothing's faked. We run everything real-time......One thing you can see, everything's reflected in the road surface. We're not doing this just locally to the track surface. You can fly out as far as you like. It goes all the way to the top of the mountain, so if the sun pokes through you'll get massive highlights where the rock formations are. And of course all the materials interact differently. The grass gets wet differently to the rock, which is different to the tarmac, which is different to the plastics....We've got a deferred rendering system, tile-based rendering system, a forward rendering system, all mixed together just to get all the variety you can [have] in certain situations and put them together......We'll be adding things like screen-space effects to actually get all the water droplets on the screen. We'll get the wind-screen wipers working [too], that'll have a full simulation pass so that you get proper droplets," Perkins explains, using his own, private debug build to demonstrate. "It's all modelled. Because of the atmospherics system, everything has to be modelled. It all sits in and writes at the same level. It's one of those things that's really subtle and helps tie it all in.....It's a mixture. There's a pixel-based system that we're using, there's a temporal-based system, there's FXAA and there's actually a material-based system as well. We've only got four systems in place and we've got another for the key points that we don't quite hit. We obsess about the small details, so we're getting another one to go on top of that, to get on top of the very final image quality issues.
