If a video card tells the game it cannot support a feature, then what are we supposed to do?
Would you buy a Smart Car and expect it to keep up with a Ferrari? When it didn't, would you take it back to Smart Car and demand they make it keep up with the Ferrari?
There is a reason why video cards come in such a wide variety of prices and configurations. The feature sets are very different.
We cannot make a video card do something it is not designed to do.
