Well, Windoes 98 (vmmon) shows very different ones: /dev/vmmon[4355]: host clock rate change request 0 -> 19 /dev/vmmon[4355]: host clock rate change request 19 -> 0 /dev/vmmon[4355]: host clock rate change request 0 -> 19 /dev/vmmon[4355]: host clock rate change request 19 -> 63 /dev/vmmon[4355]: host clock rate change request 63 -> 200 /dev/vmmon[4355]: host clock rate change request 200 -> 201 /dev/vmmon[4355]: host clock rate change request 201 -> 1001 >> any rate they want (depends on the hw capabilities). i recall seeing >> rates >1200Hz when you launch some of the media player apps -- sorry i >> forget the exact number. I have seen some apps which seem to schedule themselves using some kind of SCHED_FIFO and therefore seem to get good RT: from an ini file... # This option determines the multi-tasking capabilities of WinDEU. # The priority determines the minimum number of milliseconds WinDEU # will work before giving control back to Windows. # For example, if you set it to 20, it means WinDEU will gives # back control to Windows approximately (at most) 50 times a second. # A value of 0 means WinDEU WON'T multi-task. # (Can be changed in the preferences dialog box.)
