I am having problems with graphics performance when working with large (1.3 GB files) in Rhino5 - 64 bit. We are using Windows7 Pro, 32 GB DDR3 1600 RAM, Sata Drives, Intel I7-2600 CPU for hardware. We have tested GeForce 660 (2GB RAM) and GeForce 200 (512MB) and found the GeForce 200 cards to have superior performance.
When the Perspective viewport is rotated with a mouse action, the CPU usage immediately goes to 100% for the time the mouse is being activated. It then drops to 4% - 6% and nothing happens in the viewport. Disk usage experiences a series of “100% spikes” then drops to 2%-4%.
Are there any settings we can use to load the large file (with associated object links) into RAM so that we do not need the disk swaps?
Are there any CPU settings that can be used to activate more cores / threads and prevent “overload”.
Can a graphics card solve this problem - has anyone had success in speeding up the graphics performance for very large files?
