GrandPrix 3 2000 graphic bug

Hi!:-)
i got a new graphics card (gtx960) and installed the latest drivers for it and all of a sudden i got some huge graphic bugs/problems with the game.
Before i played GrandPrix 3 2000on a GTX660 with Geforce 320.18 driver without any problem.

I have try to install the 320.18 drivers on my new GTX960 but that is not possible.. quote "Drivers are to old for this card".

Here are some pictures of the cars that are missing parts.



wings, tires, backwing and parts of the wiels are missing.
I tried everything i know to solver this but still not luck.
Has enyone a solusion for this?.

regards
Vink
