The problem appears between 57 and 58 plotpoints. Plot3D[Sin[5 (x + y)], {x, 0, 2 Pi}, {y, 0, 2 Pi}, Mesh -> None, PlotPoints -> 57] is fine, but Plot3D[Sin[5 (x + y)], {x, 0, 2 Pi}, {y, 0, 2 Pi}, Mesh -> None, PlotPoints -> 58] shows already a degraded picture. I have a Nvidia GeForce 8400 GS like yours (without the M though). Is this a general problem with Nvidia cards?
