I recently both a new PC with the following specs:
Intel Core i7 X 990 3.47GHz
2x AMD Radeon HD 6900 Series
24 GB DDR3
Software is all installed at SSD
But now I am running C4D R12 and the weird thing happens. When I add a cube (or some other primitive object) it starts lagging as soon as I select the object and try to adjust the settings or just simply move around the camera.
If I make the object editable it all gets back to normal.
Someone knows the problem causing this issue? I already figured out when I deactivate OpenGL it all gets back to normal.
