My PC is no slouch (4790K, 32GB DDR3, R9 390, 2560x1080 res), but quite literally because of this, I'm upgrading to the 9700K, 32GB DDR4, and a RX 590 just so I can buy the 5K2K ultrawide so nr2003 looks as good as this.
All my other games look great, this is the only reason I am making the jump to >4K. Great work.
Also, I must say overall your AI is solid too. Much more fluid and lifelike. Great work there as well.
Real 3d grandstand lights. Updated large TV. Cloudy weather shadow changes. Fog. This pushed my own computer to the brink. Fog makes my game stutter for some reason even though I stay above 60FPS. But it was worth it to see the track in all it's glory.
