Kunos need to be appreciated by the more main stream industry to make a sim that not only has brilliant physics but looks up to date also.
I went over to iRacing for a while but got bored by the physics and lots of crasher kids on track. Tried to go back to netKar but just cant stand the out dated graphics.

Beta testing C.A.R.S. right now but to be completely realistic the physics is not likely to match netKar quality.

I think a better graphics engine exists (for that driving school software Kunos created), but I don't think the graphics we have are that bad. iRacing's Spa's amazing, but when I'm playing nKPro I'm more focused on driving than looking at the scenery

Alot of sim racers are drawn to big flashy loud promo videos. The actual physics of a sim obviously doesn't matter.

I've no doubt I will come back to drive some formula ford or something just for the physics, I wouldnt uninstall netKar.
But the graphics just doesnt hold, although I tend to agree with you. Theres just no excuse for sims to look like this one or rFactor does any more when you compare them to the new arcade titles.
