And another point made us feel uncomfortable: Elsa's 4.02.04.102 drivers are faster in Viewperf than the succeeding 116 drivers, but there are quality problems.
In both screenshots you notice the strange wireframe models that 'shine' through the scenes in Solidworks 99 rendered with Elsa's two 102 drivers.
This is how the scenes are supposed to look. The 116 finally eliminates the problem. The overall performance of the Elsa drivers is still poor if compared to the Nvidia reference drivers. Even when compared to each other the Elsa drivers perform inconsistently. In Viewperf the 116 is slower than the 102.
