We do not make hardware recommendations, however here are some general guidelines:
-The more processors you have available, the faster the rendering speed will be. So two, four or more CPUs will help more than anything. Design 3D CX 7 supports up to 24 tasks; a 12-core machine that is capable of hyperthreading equals 24 "tasks."
-Strata is a 32-bit application and can make use of 4 GB of RAM; a system with at least 4 GB of RAM is recommended.
-Remember, it's important to model efficiently and use appropriate render settings.
