Playing gp3 in modern systems on hardware mode

There is any way to play gp3 in hardware mode on windows 8.x?
In my case, i have a notebook with the Nvidia Optimus (Using the Intel onboard chip when not playing games). In software mode, the PO is under 30%. But in HW mode, the PO skyrocketed.
There is any config to make the game playable? Or there is any wrapper to make the game more compatible?

1. deinstall/disable all widgets that you don´t really need on your system
2. deactivate all(!) graficcard-functions in nvidia-controll-panel (Antialiasing, VSync,...)
3. set your systemaudio to 44100kHz/16bit

4. after grafic-calibration open gconfig.txt (in gamedir) with texteditor and paste these values:

;gp3 generated file - do not edit

[Software 3d] good 128 1 1280 3 1280
[*your cardname*] good 128 1 1280 3 1280
[*your cardname*] good 128 1 1280 3 1280

5. when using GpxPatch set the RCR-distances to 3800 or less (find button in GPxLap)
6. disable GpxPatch 3D-sound

7. ingame do a sound-recalibration
8. goto settings-grafics and optimize performance..


hope that helps!

The game only recognize the Intel gpu, not the Nvidia one.
I do all that things, and they don`t have any effect.
Thank you for your help!

nvidia-driver is already updated?

Yes. but even if i can recognize the nvidia gpu on gp3, the PO is always skyrockted...

..sorry, no idea further more
