First proper test was a Porsche Cup race at the Nordschleife. No AI warm-up, no practice server, straight into a grid. Probably not the sensible way to do it, but it told me what I needed to know inside a lap.
Looking into apexes, judging the distance to the car ahead, placing the car on the kerb, all of it just happened. The resolution is clear enough that your brain stops thinking about the screen. There's no pixel structure to look through, so you stop looking at the display and start looking at the track.
The field of view is the headline, and it earns it. This is real peripheral vision. Checking mirrors, feeling where a car is alongside, knowing where the edge of the track is without turning your head. It feels almost made for simracing. You're inside the car, not looking at one.
The finding I didn't expect: VR feels slightly slower than triples, and in a good way. You're more present, so the chaos of a first lap feels calmer. The same speed, less panic.
