Hi Claudio, osgNV has nothing to do with the stats, you don't need it.
As the orange bar is missing it looks like the OpenGL extension for querry pipe stats is not available. It could be that your old handward doesn't support it or the driver doesn't. Try upgrading the later. Robert. On 7/16/07, Claudio Arduino <[EMAIL PROTECTED]> wrote:
Hi Robert, how you intend for "NVidia hardware though due to use of extensions to get this time"? i have already seen the statistics but i dont have a orange bar... i have download osgNV but i dont say how to use it... my graphics card is Nvidia GeForce Ti 4600 with drivers version 6.13.10.3082.. I attach the screenshot of statistics.. please note that our model and our application are very simple and that when V-sync is disabled the frame rate is higher than 75 fps... could you please explain us if time between the two marks in the image attached is for GPU computation? thanks!!! ps sorry for my English > Hi Claudio, >If you run osgviewer and then press 's' a couple of times to full >stats you see the various phases of operation, the last phase is the >orange bar which represents the time on the GPU (this is only >available on NVidia hardware though due to use of extensions to get >this time).
