GpuTest / Failed to complete a test - What does it mean?
« Last post by Jonas MN on August 11, 2014, 02:47:01 PM »
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?

  • Fixed a bug that prevented G-SYNC from working when a G-SYNC monitor was unplugged and plugged back in without a modeset.
  • Fixed a bug that could cause framelock status to be incorrectly reported in the nvidia-settings control panel on some multi-GPU framelock configurations.
  • Improved the performance of OpenGL applications that request a large number of GPU mappings via the GL_NV_shader_buffer_load extension.
