Better performance in OpenGL with old drivers.


We have a CAVE installation with two Quaddro 5000 card and 4 screens. We have two main applications base on OpenGL we use. One is made with VRJugger and the other one with OpenSceneGraph. Both applications work in stereo.

In the last week we try to upgrade the drivers so we can use NSIGHT but we observe the performance drop from 260Hz to 50Hz. We obtain the good performance with the driver version 310.90 and all driver newer than this one we try give the same low frame rate. We also try to change all parameters of the drivers without any success.

It is possible to submit this case to NVIDIA and expect to have a correction or explain us or to correctly configure the drivers if the solution is so simple.

Thank you, Sylvain
