[QUOTE="Marcus Venturi, post: 1103336, member: 121570"] In normal operation every frame takes one single blit. In 3D mode I do 2 blits (left/right) into a backbuffer and then blit all to the screen. For this purpose I use the DX9 call "StretchRectangle". As the normal blit takes only 4.9ms I assume that this call is slower on your GPU.
