The NVIDIA 177.76 Linux driver
was released a week ago with a few changes from the earlier betas that made it out of NVIDIA's Santa Clara campus roughly a month ago. Now today NVIDIA has issued another Linux beta driver, which is at version 177.78.
The only changes since the NVIDIA 177.76 release is fixing a performance regression within the GtkPerf GTK benchmark, using /sys/class/power_supply for determining the power-state within the driver, and fixing corruption when using SLI in SFR mode with OpenGL-based composite managers.
