Dear members, in a dell 650 workstation i have twin Xeon CPUs and NVidia Quadro screencard installed. Supposed to give good to excellent performance, however the rendering speed is extremely slow. The computer runs very slow compared to much less powerful configurations. There is no system faults ( multiple thread is active )and no hardware conflicts. ( no viruses on system ). in addition installed apps, and utils is kept to a minimum. Further, the system accepts surprisingly low amount of polygons. One friend told me that there could be problems with speed due to the construction layout of the Xeon cpu in combination with NVidias screencard on Dell computers. Do the forum members have any experience / information about this? What to do to solve this speed problem? Any advice is appreceiated. thj,.
