What is FurMark?
 
FurMark is a very intensive OpenGL benchmark that uses fur rendering algorithms to measure the performance of the graphics card. 
Fur rendering is especially adapted to overheat the GPU and that's why FurMark is also a perfect stability and stress test tool (also called GPU burner) for the graphics card.

The benchmark offers several options allowing the user to tweak the rendering: fullscreen / windowed mode, MSAA selection, window size, duration.

This benchmark requires an OpenGL 2.0 compliant graphics card: NVIDIA GeForce 5/6/7/8 (and higher), AMD/ATI Radeon 9600 (and higher) or a S3 Graphics Chrome 400 series with the latest graphics drivers.


The startup interface allows you to tweak the benchmark features such as:


Benchmark mode or stability test mode (for overclockers) 

GPU temperature monitoring and recording in a file 

Fullscreen or windowed for each type of run mode 

Window size selection (standard or custom) 

MSAA samples selection 

Benchmarking parameters: time based or frames based 

Contest Mode


The Contest Mode allows to enable the "anti-cheat" protection against some usual techniques used by cheaters to get a high score. 
This mode is useful to organize a contest based on this benchmark. 
If the Contest Mode is disabled, the final score is displayed in a simple message box.

If the Contest Mode is enabled, the final score is displayed in a more elaborate dialog box.

The default benchmark settings are: Fullscreen, MSAA None, 1280x1204, duration 1 minute. At the end of the benchmark, just read the o3Marks score in the result dialog box. The o3Mark score is simple: it's the number of frames that have been displayed during the benchmark. Thus the higher the score, the more powerful the graphics system is.

Xtreme Burning is a mode where the workload of GPU is maximal. 
In this mode, the donut is fixe and is displayed in front side which offers the largest surface. In this mode, the GPU quickly becomes very hot.

The Xtreme Burning mode can be started in command line or directly by launching the file start-Xtreme-Burning.bat. 
This mode is perfect for testing your new overclocking parameters.

Okay let’s see the main bugs the Catalyst 9.1 has brought to OpenGL users / developers:

OpenGL

* 1 - first of all, a nice crash in one of the most basic OpenGL function, glGetString(GL_VERSION), when an OpenGL 3.0 rendering context is enabled.
With an OpenGL 2.1 context, there is no problem.

* 2 - second bug with Catalyst A.I. (A.I. for Artificial Intelligence) 
(or CCC A.I.):

o CCC A.I enabled (slider on Advanced): crash
o CCC A.I enabled (slider on Quality): OK
o CCC A.I disabled: OK

The crash (in the glTexImage2D function) with CCC A.I. came from texture pixel format. Some textures used by FurMark were in 3-channel RGB format and when CCC A.I. is set to Advanced, I think the driver expects a 4-channel RGBA texture to perform some clever (what?) anti-aliasing tricks. 
And if the application provides a 3-channel RGB texture, the driver crashes in glTexImage2D. So I simply bypassed Catalyst bug by setting to 4-channel RGBA all textures used by FurMark. Now, no matter if CCC A.I is enabled or disabled, FurMark works fine.

Some Geeks3D readers have reported crashes with other OpenGL applications like Second Life. Disabling CCC A.I. fixes these crashes.


FurMark 1.6.5 ChangeLog:

* Change: Workaround for Catalyst 9.1 when Catalyst A.I is enabled: all textures used by FurMark are now in 4-channel RGBA format (in the previous versions, some textures were in 3-channel RGB format…).

* Change: the OpenGL version used by the renderer is now displayed in stability test mode (near renderer’s description) - thanks to David Legrand ;)

* Change: by default the creation of an OpenGL 3.0 rendering context is disabled. If you want to enable it, just start FurMark in command line with the /gl3 parameter or use the batch file called Start-FurMark-OGL3.bat.

* Change: small modifications in OpenGL 3.0 context creation.

* Change: workaround for Catalyst 9.1 bug in glGetString(GL_VERSION) when an OpenGL 3.0 context is used.

* Removed: timer check in contest mode.
