I use either the i810 built-in graphics or one of the generic XVGA clone boards without high-end graphics accelerators. The high-end accelerators may use large DMA transfers to main memory that cause rt latency problems. The low-end graphics cards eat up a lot of CPU rendering the 3D view in software, but that is at least pre-emptable by rtai, so it doesn't interfere with the motion. That seems to be born out by what performance I get, and which machines get latency messages and which don't.
