To be honest I think it likely says more about the game. As Beanie says the Dirt games have never been a graphical tour de force.
It’s just weird that it’s the first thing we’ve seen (I think) running on next gen Xbox and even then it’s on an S.
I think it’s being shown on S because the expectations are lower there, but I don’t think X will look that much better outside of a resolution bump.
It has made me more cautious about considering either at launch though. Money might be better spent on a PC. GamePass Ultimate covers it anyway.
And with Oculus Quest 2 just announced (Facebook issues aside for the moment), and Switch Pro 4K AI upscaling rumours gathering momentum there’s actually a lot out there to compete for the spare space around the telly.
