Failed to complete a test - What does it mean?

[Jonas MN]

I ran GPUTest 0.8 on a MacBook Pro with a NVIDIA GeForce 8600M GT 256 MB

I have run through the different tests, but when I run PixMark Julia OpenGL 4.0 The screen flickers and the drawing can not be seen. What does this mean? Is the graphics card bad?

Hi Jonas,

the PixMark Julia OpenGL 4.0 requires the support of FP64 in the GLSL. And I think the 8600M GT does not support OpenGL 4 FP64.
Can you run the PixMark Julia FP32 (OpenGL 2.1 / 3.2) ? What is your OSX version?

Hi,

I run Mavericks.

I have tried running all alternatives of PixMark Julia and they all flicker. With FP64 the entire screen flickers, with the other versions only the window that runs the test flickers.

G8x (your videocard as 8600M GT) has up to OpenGL 2.x/3.x support but OpenGL 4.x requires Fermi (GF 400- or 500-series) or newer card. lool

So that means that there is something wrong with my graphics card since it can not run PixMark Julia FP32 or lower?

I am experiencing flashing screen when I work with my computer now and then, but it does not seem to be connected to any specific program or kind of screen output, that is why I try to figure out where the problem lies.
