Weather
1. NASA data was used to accurately map out the night sky — so wherever you are in the world you’ll see the correct star constellations for your location.
2. If you’re lucky, you’ll get to see the northern lights — it’s possible to see the aurora borealis from the northern tracks in Norway, Scotland, and Canada.
3. All clouds are full 3D models to ensure accurate light diffusion from the sun. They’re calculated at massive distances in a fully volumetric form, so thin clouds cast lighter shadows than dense storm clouds, and their color impacts the feel of the landscapes and cars.
The Environment
8. High resolution NASA data was used to accurately map landscapes and mountain formations — which were then tweaked to ‘improve’ on their natural beauty and make them perfect for high-speed racing.
9. The team spent weeks out on location and covered a minimum of 200km every day to get a feel for each country’s roads and atmosphere. They captured thousands of photos and recordings along the way, in all weather conditions and different times of day.
10. Road tarmac textures are hand-modelled rather than tiled or tessellated. Stones and bitumen are all placed and then rendered procedurally to give realistic surface detail with huge visual variety and no repeating detail on any road surface.
Flora and Fauna
13. Some tracks boast more than 1.2 million road-side trees — and this number keeps going up as the artists try to out-do each other as development progresses.
14. There are more than 100 different varieties of trees, bushes, mosses, and flowers. The team consulted botanists at Kew Gardens to learn which plants would naturally grow in each location.
15. Wildlife is realistically tied into the day/night cycle. You’ll see flies and butterflies only during the day, and moths and bats only at night.
The Cars
21. A typical Driveclub car is made up of 260,000 polygons. The staggeringly detailed cars you see in promo videos are the same models you drive in the game — they’re not pre-rendered CG versions.
22. Each car takes approximately seven months to create — from initial licensing, reference collation, CAD data processing, asset production, physics modelling, through to the final car in-game.
23. Evolution snapped in excess of 1,000 photos of the interior and exterior of every car as part of the reference gathering.
38. Each reference car was fitted with at least 16 separate microphones to authentically capture the sounds of the engine from 360 degrees, inside and outside of the car. Some had four mics on the exhaust alone.
39. In-game, the engine sound reacts to your perspective. Pan around a stationary car gunning its engine and the sound shifts with the camera position (relative to where the engine is).
40. When you race, the engine sounds are different based on which of the six camera views you choose — inside or outside of the car. You’re not hearing the same engine audio with a filter — it’s all recorded separately.
Handling and Physics
44. Although not a sim, Driveclub’s handling model is based on real world physics, using technical data about performance provided directly by the manufacturers.
45. To fine-tune the performance of every vehicle, a virtual “rolling road” test is used to check acceleration, top speed, weight distribution, and braking performance.
46. Aerodynamics are physically modelled. For example, activating DRS on the McLaren P1 affects the levels of downforce to increase top speed and acceleration.
Artificial Intelligence
48. The AI drivers adapt their racing tactics and braking strategy based on pressure from players or other drivers. When alongside them, they will try to brake deeper into the corner.
49. AI drivers always try to predict overtaking opportunities based on the track, the performance of their car relative to opponents, and also how opponents are driving at any given moment.
50. When an AI driver has a car with KERS (Kinetic Energy Recovery System) fitted, they will use the energy strategically at opportune moments to pass or block opponents on the track.
