I am running Pro/Engineer 2001 on Windows 98. Does anyone know if it is possible to improve the shading performance of a model with only 8MB on a 2x AGP card? My system is a Celeron 400Mhz with 128 MB RAM with only a AGP 1.0 slot (1x/2x). It cannot accept one of the AGP 2.0 4x/8x AGP cards. The PCI slots are also of the older configuration and will not accept the newer PCI cards. Wire frame images are fine, but when I view a simple model with shading, portions of some of the features to not appear and the shaded surfaces of those that do look very grainy and even looks this way when the model is not being dynamically rotated. Also, colors to indicate surfaces and edges do not appear. System is set at 10280 x 1024 with 256 colors. Any help would be appreciated.
