GfxBench2D Client Updates for AmigaOS and Windows
Posted by Hans de Ruiter
Both the AmigaOS and Windows versions of GfxBench2D clients have been updated. There was a minor issue in which a graphics card whose name contains particular characters would fail to save. The reason is that files cannot use certain characters, and so attempting to save a file with say, a slash '/' character (which is used to separate directories in a path) would not work. This issue has now been fixed.
GfxBench2D for Windows 2.6
Posted by Hans de Ruiter
The Windows version of GfxBench2D has received another update. This version includes a workaround for an issue with buggy graphics drivers. On a small number of computers it would hang at the WritePixelArray test. This was due to a driver bug affecting the CopySubresource() function. It would allow the source-buffer to be locked for writing before copying of data from that buffer to the graphics card had completed, potentially enabling the old data to be overwritten before it had been used. Fortunately, there was a different method to wait until the operation was done, which waits for the GPU to be idle. This same method is used prior to each test to ensure the most accurate results.
