Perfect, I put D2D_POINT in DXDraws and work ok.

I used undelphix 1.06 and not 1.07 by stop of some seconds the first time I paint a sprite with alpha with undelphi 1.07 (With 1.06 works well).

I solved other problem, texture with alpha have limit 1024x1024 px for ATI. I have a NVIDIA and limit are 2048 x 2048 but people with ATI say me a problem and I solve it limit texture (with BlendMode := bmBlend) to 1024 x 1024.

Kotai.
