<br>
My company makes a program that uses OSG for 3D windows of terrain models. I am not the OSG programmer. But a user sitting next to me has trouble with a totally new PC with good specifications and an NVIDIA Quadro P4000 graphics card. The 3D maneuvering is lagging to the extent of being difficult to use, while other PCs with much less specs have totally smooth maneuvering in the same model.<br>
<br>
Any tips on how to go about finding out what the cause could be are welcome!<br>
<br>
<br>
Thank you!<br>
<br>
Cheers,<br>
