That graphics card is a 2d card, which requires rendering to be in software. That system supports a mid-range 3d accelerator, GXT3000P. Hardware rendering in DX will take advantage of the OpenGL support in that card. Your workstation will support a 2nd processor, if you don't have one already. Computational operations in DX can run in parallel with the two processors. Since your dataset is not that big, my guess without seeing any further information, is to get the hardware accelerator.

Dear list members, I'd appreciate if you can share some experience with dx. We have IBM's RS/6000 43P Model 260 with 256MB RAM. We use data explorer to <100 * <100 * <20 rectangular gridded scaler/2d-vector data. We use 3-D isopleths the most. Our problem is that when we use dx interactively, rendering takes long time. So we want to figure out where to spend money to let the system respond more quickly. Our system has 256MB, and graphic card is POWER GXT120P (or 240?) Graphics Adapter. We have OpenGL (is this a library or a hardware?), and OS is AIX 4.3. -- yosuke kimura Center for Energy and Environmental Resources The Univ. of Texas at Austin, USA
