So I was so ulucky that I've found 16 badly coded games made on most popular engines (UE3, Source, ID tech 4, Cry and few others).
I'm talking about CoJ because it's most visible there but It's not only visible there -.-
Like I've already said, you won't notice MS if you're CPU bottlenecked and I was bottlenecked quite often with qx9770@4GHz with 4870 CF...
