I use DelphiX and Delphi6. What do you use Pailius?

Additionally, I've tried it to put system memory but performance's fallen. Also I need to scrooll stretched image(texture) on the screen (like Commandos 2 and lots of RTS game' s zoom scroolling). I use NVidia TNT2 M64 32MB video card. Do you think problem will end if I change or upgrade it? Please, open dxdiag and disable 2D hardware accaleration then compile one of your simple stretch project, you can see zoom effect is clear. I think it depens on some accaleration features and there should be a way to prevent it using directdraw properties.
