Driver Crashing Right now I am having a problem with driver crashing. I am getting an "Nvidia Open GL Driver Lost Connection" I am running OSG 3.2.1 RC-3 on a Windows 7 machine. This also happens with OSG 3.2. I am running multiple 2 Quadro cards and 4 processes each displaying on 1 screen. I have Quadro Sync+ warping and blending setup through the driver. This occurs infrequently (out of 4 computers running this overnight ~14 hrs I got 1 to fail).
My overall system load seems good. I am running at 60 Hz. I am getting some large hangs (over 300 ms) at points. I am not doing any paging, and these do not seem to be related to either a location or creating new objects. (For creating new objects I am just adding a reference to an existing model that was loaded at the start). My GPU memory usage seems good; I am at like 70% usage at peak. I strongly suspect the problem with the driver failing is related. Any advice in terms of tracking this down would be appreciated.
