The OPC project group has approved the latest version of Viewperf, the industry-standard benchmark for measuring OpenGL performance. Viewperf 5.1 can be downloaded for free in this issue of the GPC News. Viewperf 5.1 did not require changes to current viewsets, so results are comparable to previous ones under Viewperf 5.0.

The new version of Viewperf includes a compile-time flag to determine whether function pointers are used in the inner loops or not; submitting vendors have the option of using or not using the pointers. Viewperf 5.1 also corrects the walkthrough mode behavior on Windows NT systems and provides better documentation.
