Perfect.

Delete line {$Define DrawHWAcc} all graphis are ok and I can load circuits > 4096 pixels and and I can use Alpha without lowering fps too much.

Only one problem not solved deleting {$Define DrawHWAcc}: The first time that shows sprite on screen the game freezes a second when DXSpriteEngine.Draw is done (without do3D no freezes). I try to load all the sprites before entering to the circuit, but there is some as the cars ghost that cannot be created until an event happens and when it happens game freezes a second.

Some solution?

Thanks.
