Image blur filters are commonly used in computer graphics – whether it is an integral part of a Depth of Field or HDR Bloom, or another post process effect, blur filters are present in most 3D game engines and often in multiple places. Blurring an image is a fairly trivial thing to do: just collect neighboring pixels, average them and you get your new value, right?

Well, yes, but there are different ways of doing it with different visual results, quality and performance.

In this article I’ll focus primarily on performance (and quality trade-offs), as the difference in cost between a naïve and a more optimal solution can sometimes be an order of magnitude, but also different algorithms can be more optimal on different hardware.

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.

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

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.

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?

OpenGL 4.5 Specification Released

Khronos publicly released the OpenGL 4.5 specification today, bringing the very latest functionality to the industry’s most advanced 3D graphics API while maintaining full backwards compatibility, enabling applications to incrementally use new features. The full specification and reference materials are available for immediate download from the OpenGL Registry. New functionality in the core OpenGL 4.5 specification includes:

  • Direct State Access (DSA) – object accessors enable state to be queried and modified without binding objects to contexts, for increased application and middleware efficiency and flexibility;
  • Flush Control - applications can control flushing of pending commands before context switching – enabling high-performance multithreaded applications;
  • Robustness - providing a secure platform for applications such as WebGL browsers, including preventing a GPU reset affecting any other running applications;
  • OpenGL ES 3.1 API and shader compatibility – to enable the easy development and execution of the latest OpenGL ES applications on desktop systems;
  • DX11 emulation features – for easier porting of applications between OpenGL and Direct3D.

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?
