Terminal Reality has said that the new Ghostbusters game will run at the same performance level on PS3 and Xbox 360.

Confirmation came at last week's Sierra showcase event, where Ghostbusters was up and running on both Sony and Microsoft's machines.

"We're demoing on both systems so you can see the game is fully running on both systems at the same performance level," said executive producer Brendan Goss.

However, there will be some differences under the bonnet. "Something unique for the PS3 is the displacement mapping," said Goss, demoing a scene where a Ghostbuster is walking down a cobbled alleyway.

"The ground you're looking at is only two polygons, it's a completely flat plane. We get the illusion of the 3D brick surface because of the relief map." Well there you go.

Ghostbusters is out on PC, PS2, PS3, Xbox 360, Wii and DS this autumn.
