Hi every body

I registered CT scan and MRI. When I switch to 3D mode (VR and GPU) only with CT scan or MRI loaded performance is outstanding.
Problems start with CT and MRI scans loaded together. In 3D mode any mouse manipulation causes renderer window freezing and its not possible to work with that. Picture is skipping with long delays. Looks like my machine is not enough fast ?

Any suggestions ?

My medInria version is 2.2.0 64bit, Windows 7 64bit rating 7.8, 64GB RAM, i7 3.3GHz, AMD Radeon HD 7900 Series PCIE 3 264.0 GB/s

best regards

Pawel
