Nvidia GeForce 6600 better than Nvidia GeFordce 7800GT ?

Hi, something weird happens in my PowerPC when testing a scene in unity.

First of all my PowerPC’s configuration is :

RAM : 3.5 GB
CPU : 4x2.5 GHz

Licence : Unity Pro 1.5.0

When using GeForce 6600 I obtain 70 fps and when using GeForce 7800 I obtain 30 fps. Why am I having less fps with a 7800 than with a 6600 ?

Are the game’s visual settings identical?
If a driver or device difference, or game-settings difference has one the newer card doing more than the other, or using another means to draw, it can slow it down regardless.

It’s possible something is cutting the FPS down deliberately, so as to not use up as much power, a driver setting perhaps. Unity Web player for instance is set not to go above 30fps.

Does this happen in this one scene, or in all players you’ve tried?
