Schooner: Please check your latency-test results with the NVidia drivers loaded and working. I found it very hard to backtrack to the nouveau or vesa drivers when my 8 or 9 microsecond latency-test results were replaced by several hundred milliseconds of lag. I was limited to about 2 ipm while doing sw stepping on an older athlon single core board. The motors sounded very ragged, and were simply were visibly stopping while glxgears was running. In short, 5 years back up the log, using the then current NVidia driver kit was IMO, totally incompatible with linuxcnc as it locked out the IRQ's needed in order to get the performance it gives to the video. If that situation has improved, and NVidia drivers now play well with LinuxCNC, I'd be happy but unaffected as the real machinery here is being driven by D525MW intel boards. I do have an NVidia based GeForce 8400 GS card in this machine, but have studiously stayed away as generally, the nouveau drivers are good enough to watch a new site video. Thank you.
