Ok, try the fifo_* options now (leaving xvideo no in also). Try fifo_moderate first, then fifo_conservative. I'd expect fifo_aggresive to be worse, but maybe not. No need to send any more log files for these runs, just check how the screen noise looks. depth 24 is the least optimized mode in the s3virge driver, as I tend to run depth 16 most of the time myself, and I don't think anyone else has really looked at it recently. -- Kevin _______________________________________________ XFree86 mailing list XFree86@xxxxxxxxxxx http://XFree86.Org/mailman/listinfo/xfree86
