I have 3 month old Macbook Pro with following: Mac OS X Lion 10.7.4 2.4 GHz Intel Core i7 Memory - 8 GB 1333 MHz DDrs Video Graphics - Intel HD Graphics 3000 512 MB - AMD Radeon HD 6770M Parallels Desktop 7 for Mac (7.0.15095) Windows 7 Home Premium 64 bit (Service Pak 1) Problem: I am running a HD 3D program called Sidexis that is used to create color 3D models from CT scan. For some reason it will not generate the 3D model and movements are slow and "jumpy". I have 4GB of Ram dedicated to partition. I think Parallels is using the Intel HD graphics 3000 (512 MB) card which is not adequate. Is the solution to have Windows utilize the AMD chipset? if so, How do I do that?
