Don't calibrate the graphics.
I'm really not trying to be snide here.
I have often had GP3 crash when I try to calibrate the graphics after installing a new carshape, for example, but GP3 will run perfectly well anyway if you choose not to do so.
The only thing that the graphics calibration seems to do is for the game to recommend a screen resolution and choose the automatic graphics settings. With a new computer, you will very likely be able to run GP3 satisfactorily at all the maximum graphics settings, so don't calibrate the graphics and then choose the manual graphics settings option in the advanced graphics menu.
