Gaming on linux.. anyone???

I’ve been a windows user for years now. i have also tried and used linux for a year now. i love computer games especially those released on M$ under the DirectX platform. i really like linux but the downside is it lacks support for games such as those realeased under MS. im not sure if im informed enough on this matter. i was wondering if there a directx type of software for linux. one that could accelerate games for the platform.

is there anyone willing to share their ideas on this???
