I am confused. I have NVidia GeForce PCX 5750 in my PC. (I know it's old -- my son stole my real graphics card.) I was only getting frame rates of around 8 to 12 fps, and strange things happened with other windows overlapping the simulation window.

So I tried the new shaders and the frame rate jumped to about 68 fps! However, the colours have all changed too. Everything is several shades lighter and I can't adjust it back using the graphics settings in the simulator. Is the ground supposed to be green in the tutorials?

I still have strange behaviour when I overlap a window. For instance, I just put the Dashboard over the top of the simulation window and half of the simulation is showing in Physics view and the other half is fully rendered! It changes as I slide the Dashboard up and down the screen. Really weird.

So what is the recommendation? Should these shaders be used for all older NVidia cards?
