Default Re: OpenGL performance issues on SLI'd GeForce 8800's

Yes, I have tested against other "real" benchmarks for example the following:

Code:
Configuration       RHEL4 1 8800          RHEL4 2 8800's SLI
3dsmax-04          3.656                       0.1897
catia-02              10.28                       0.1661
ensight-03           14.23                       0.1278
light-08               8.235                       0.2644
maya-02            19.51                        0.3305
proe-04               7.545                       0.1151
sw-01                 6.157                       0.2864
ugnx-01              3.335                       0.02893
tcvis-01              4.356                        0.05313

This is a comparison of runs of SPECViewperf. I only use glxgears as a simple openGL application to demonstrate the dramatic effect of how enabling SLI for me inhibits my performance... 22,000 frames per second going down to 2.4 frames per second specifically. Similar performance characteristics are seen in my SPECViewperf benchmarks as well.
