I thought this may help someone as it helped me. This only affects AMD ATI Radeon graphic cards.
*DISCLAIMER* use at your own risk i am not responsible for any damage caused to your computer by using beta drivers
After spending alot of time testing between my different gaming machine setups i found a driver combo that runs viewer 3 great.
First 11.8 catalyst drivers are very problematic, especially if you are running crossfire(dual gpu) setup like me. So for overall stability i'd recommend rolling back to the 11.7 drivers.
Secondly there is a preview version of OpenGL 4.2 drivers which are *Amazing* download immediately and thank me later.
These drivers along with the viewer 3 beta drivers makes the experience smooth as butter. *For me anyways*
So make sure you install the 11.7 drivers first then install the opengl drivers overtop of the 11.7 drivers.
The opengl drivers only affect the opengl drivers used. So if u have 11.8 and install the opengl 4.2 preview drivers you'll still be 11.8 basic graphics drivers which are unstable.
Let me know if these work for you.

Thanks Drager. I updated my video drivers to version 11.8 when I saw there was an update. Performance seems the same with 11.8 and11.7 drivers. If you set the antialiasing to 2x there will also be an increase in performance for slviewer2. I also uncheck the anisotropic filtering in slviewer2.

I use a HD6950 viedo card and when I upgraded to catalyst 11.8 my viewer 2 V3 video performance became erratic and jumpy. i reinstalled an older version of the viewer..still bad. I ran Firestorm and it works fine. I noticed while viewing my AMD System Monitor that Viewer 2 is more GPU intensive whereas Firestorm is more CPU intensive. I have been happy with viewer 2 for a long while but i guess I will have to switch to Firestorm.

Hello, Drager. Thanks for the info. I have a few questions.
I am using 11.8. Would I download and use the driver you linked to in addition to 11.8 or in place of 11.8?
When you say viewer 3 beta driver do you mean the actual viewer 3.0 or is there an actual viewer 3 beta driver?
I don't have crossfire, would your recommendations be of benefit to me?
Thanks for your help

Hello Charolotte, I think I might be able to help you with your questions. The link provided is for beta drivers for ATI video cards. They are beta so they might help performance or maybe not. I rolled back my video drivers to version 11.7 and there was no difference from the version 11.8 video drivers. I think you know there is the v3.0 slviewer and also a beta v3.0 slviewer and not v3.0 slviewer drivers. I like to uninstall the video drivers before I update to newer drivers. I use the uninstall in the control panel to remove the drivers.

Thank you, Rc.
I had not previously uninstalled the old drivers when installing the new drivers, but I saw that is part of the instructions in the link provided and your doing the same reinforces that this is a step I should be doing.
I do know about the beta viewer, thank you for that clarification.
Once I roll back to 11.7, will I also be wanting to be using the open GL 4.2, or is it one or the other type thing?
Thank you for your help and patience with my questions.

Hello Charolotte, You are correct in saying one or the other. openGL and everything you need is in version 11.7 drivers. There is no need to install anything else. You can use just the version 11.7 drivers or just the beta preview drivers. From what I read on the ATI web site version 11.8 has the updates for openGL but I could be wrong. You are very welcome and glad that I could help.

There is a slight misconception about my post. There are actually 2 parts.
One is rolling back to 11.7 which will include opengl drivers. However they will not give you the performance boost just stability.
The second part is to download the link for the openGL preview drivers. These specifically update the opengl drivers for your card and overwrite the 11.7 opengl drivers.
What this achieves is stability of the regular 11.7 overall graphic drivers and the improved performance of the opengl 4.2 Preview drivers.
Both are needed to get the most out of the card.

Hi Derry I have tested with viewer 3 and firestorm. They both work equally well with the driver setup i posted however, i have a very beefy system so its hard to notice much difference.
In general tho i believe firestorm/phoenix always seemed to do more on the gpu side. I think since firestorm uses a huge amount of base code from viewer 3 its not the case so much.
