Subject:   -37- Frame control on low- and mid-range machines
Date: 8 Apr 94 00:00:01 EST

  Frame control on low- and mid-range machines: Currently, the video
  clock (pfInitVClock, pfGetVClock, pfVClockSync) is supported only
  on systems with VGX, VGXT, RealityEngine, RealityEngine2, Elan, XS,
  Extreme, and Impact graphics hardware. On other systems,
  pfVClockSync returns immediately. Because libpf normally uses
  pfVClockSync for frame rate control, frame control is not rigorous
  on other platforms.
