The controls are there so you use 2 hands to control turning and throttle, it makes things far easier, trust me. The following keys are GP4's defaults from memory:
A and Z are the acceleration and braking respectively, , (<
and . (>
are the buttons for turning left and right. Toggling pit in setting is "Enter". To change the view point, use Page Up. Page Down defaults to a chase view, much like older and most other racing games. Default reverses this view, so you're looking backwards. Home puts the focus on your car, in whatever viewpoint it may be in. "Right" defaults to the T-cam view or the in-cockpit view. "Left" I think defaults to the TV camera position. Insert switches to a director's cut, and should only be used when you're not controlling the car because the focus may not be on your vehicle.
I hope this helps. Please don't be infuriated, GP4 is a great game, it just needs a little love and attention to get the best out of it.
Regarding the white textures, I think setting the texture detail in the "Options" menu to the maximum setting solves that problem. If not, use search as the problem's been around for a while.
