Hi Speeeder, welcome to PGD and nice screenies!

I recommend checking out the turbo site for the lastest version of UnDelphiX by Jaro as it has been updated to include hardware acceleration on top of the other updates that allow the use of DirectX 8.1 and I think DirectX 9 aswell.

It will help up the performance of your game if you are having speed issues using the alpha effects.
