Hi, thank you for your detailed reply, Robert! Yes, you guessed right, I'm using Windows 8 ;) My hardware causing the trouble is a AMD-HD7970. I tested the program on a Nvidia gtx-970 and there where no frame drops at all! Although the hardware specs of the gtx are a bit better, I would have at expected at least some frame drops. So it really is a driver issue.
I used the windows process explorer to verify, that memory is not unloaded from the GPU when looking at other directions, which did not happen on both machines. The main memory is freed after the upload, so setUnRefImageDataAfterApply does its job well. So it might be the frame caching issue. I will have a look into those sync settings you suggested, when I need to use a larger model. Until now, I'll just leave the culling disabled.
