We would like to welcome you to the Graphics Hardware/Drivers community. The intent of this community is to allow users to collaborate on their experiences specific to graphics hardware and drivers. Also, this allows Mentor to post information we discover to help our customers make decisions about their graphics hardware and drivers. We will kick this off with some general information.
Tested graphics configurations
You can find the details of our graphics card and driver validation in the 7.9.4 release highlights document available here: http://supportnet.mentor.com/docs/201206008/release_docs/EE7.9.4_rh.pdf (search for: “Graphics Card and Driver Version”)
One important note is that we’re aware of issues with the AMD FirePro V5800 and V5900 cards – for more details below.
Please share any additional hardware or driver versions that you know work correctly or which you found to cause trouble one way or the other.
Known driver and graphics cards issues
AMD FirePro V5800 and V5900
One of our customers reported problems with drawing narrow vertical lines on the V5800 card.
The problems were not reproducible using V5700.
As of today, we have successfully reproduced the problem on our side using V5900 cards and we have a fix integrated and planned for delivery with the next major release of our software.
When should I update my graphics card drivers?
Although many graphics card vendors suggest that you always keep drivers “up to date”, many people have learned the hard way that this may not be a good practice when using an older graphics card. Many graphics card manufacturers also acknowledge this issue.
Even though the new drivers state support for many old graphics card families and seem to work with them most of the time we’ve often seen that things don’t work as well as they used to on an older driver.
From the outside it looks the older drivers are often a better fit for the older graphics card and the newer ones seem to be targeted, tuned and tested mostly for the newest cards from a given manufacturer and may not work as well on old hardware.
Our suggestion is to be careful when updating drivers especially if things work well using the current one. We also suggest you always check release notes to see what kind of changes or fixes were made to avoid updates if they will not provide any value to you. This approach allows you to minimize the risk of being impacted with this kind of problem.

If your NVIDIA based graphics card is an older model, then we suggest you update your drivers only if you are experiencing problems while running newer software on your PC.”
