Is it really true the DiRT will only... ONLY work on the specified requirements?

If your computer does not meet certain minimum requirements, it does not work. Wouldn't that be quite logical, no?

ps. My main issue with Dirt is that it's quite turd.

My issue is that in dIrT the carrier don't save.
But i've figured how to solve it: sell this pieace of shit. Micromachine v4 has a better physic engine than DiRt

It can work even if your computer doesn`t have the requirements for running the game.
But there are a lot of things that probally will occur if your computer don`t, for example meet the minumum spec needed to run the game.
The most normal thing would be that the game would be very very slow, like 1 FPS, the second that it simply would not start, the third would be systemlock, blue screen and death to your computer, but in most cases it would be solved witha restart
