On Windows some users experience a "pure virtual function call" error on startup:
According to this user, 14.9 and 14.9.1 beta drivers work correctly, and beta drivers 14.9.2 cause a crash.
On Linux, the 14.9 driver causes our application to crash under some conditions. All persons experiencing this problem have AMD GPUs:
I am unable to produce any of these errors with an R9 280 on Windows 7 or Ubuntu 12.04. I can provide some Steam keys for the application if the driver team doesn't mind using a Steam account to test it. The application will install for both Windows and Linux.
The problems on Linux appear bad enough I have temporarily removed support for AMD graphics on Linux from our Steam page.
Our application makes use of most OpenGL 4 features, so it might be a helpful tool for future testing before releases.
