Hello,
I am writing software to display a multi computer display for syncronized video. I have 4 PNY Quadro FX 3000G cards and am having problems getting the cards/software run correctly. I have an OpenGL application that runs on each of the computers with the Swap Lock enabled. I have enabled the frame lock from the nvidia-settings. My problem occurs only when the swap lock and framelock are enabled. I am displaying data of frame times and without the locks enabled I get a solid 60hz refresh(but the displays are not synced). Once the syncs are enabled, I have recorded and can see visually pausing happening one each of the visuals. The pauses do not happen at the same time on each channel. I have very little info on programing these cards in opengl for linux. If anyone else has seen this or can tell me what to look at that would be of great help. Also if there are any examples or documentation that would help out too.
thanks in advance.
Rob
