8756 G-Sync No Longer Works!
I am posting here because no one from nvidia ever seems to look in the workstation area - sorry.
I have three machines with FX4500 cards connected to G-Sync boards. After installing the 8756 driver and setting things up again our OpenGL apps stopped synchronizing. The nvidia-settings setup works fine (as before) and it shows that the machines are sync'd. However when we run any application that uses the GLX_NV_swap_group extensions to activate things the join functions fail! The query function shows 1 swap group and 1 swap barrier. But the attempt to join fails.
HELP nVidia! Guess we will have to downgrade...
