demo = spoilers?

I think You should at least check if it the demo runs properly on Your computer (from a technical stand point). There's nothing worst than spend the money on a game You'll be unable to play.

True on that.

I bought Need For Speed: Shift for 50€ and it didn't even work very well on my computer even though I have half better specs than the ones given in back of the Shift's box.

I searched for patch or hotfix, and there's no such thing which would improve the gameplay in any form, just adds more cars etc. .
Also, I noticed that people with almost the same specs than mine, get same bad results and people with lower specs get great gameplay without lags.
