When selecting vehicle, I find the background totally black and can't see any models of the podracer.

Then I click 'OK' and start the race, but it only shows white screen and the shadows of the pods.

Screenshots has been attached.

There should be a ddraw.dll in the Star Wars Racer folder. Check if it's there.

Of course it's there.

Looks like the game is not using it though. Try replacing it with dgVoodoo.

I have tried this before, but it did not work...

What happened?

What are your system specs?

I copied all the files from the folder of 'dgVoodoo\MS' to the game folder, and run the game, but nothing has changed and I still can't see any 3D models of podracers.

I run the game on 64-bit Windows 7 and GeForce GTX 1050 Ti.
