UseDeviceBitmaps
With this option selected device bitmaps (off-screen video memory) are used.
Default
selected
Effective
after rebooting
Applications can store bitmaps, which are not longer displayed but should be recalled quickly in the video mem-
ory (off-screen video memory). If you experience errors as display corruption or crashes and suspect that they
could be related to the usage of device bitmaps or to the display driver in general, turn this option off.
The simplest possibility to bypass all conflicts in storage management is to deactivate the use of device bitmaps.
However, this will cause a decrease of graphic performance in most cases.
In general the following simple rule brings good results: For all resolutions smaller than 1600×1200, 32 bpp use
device bitmaps else do not use device bitmaps.

Perform transparent bitblt in hardware
This option has no effect on the display properties of A
Synchronize with graphics engine
With this option not selected the graphic performance can be increased accepting a longer interrupt time.
Default
selected
Effective
after rebooting
Extensive graphic operations may cause modem data-loss (lost bytes). In this case, the Synchronize with
graphic engines option can be selected.

Enable write combining
With this option selected write combining is enabled on CPUs with Pentium Pro, Pentium II, Pentium III, Pen-
tium IV or Celeron processor.
Default
selected
Effective
after rebooting
Write combining enables the CPU to transfer images to the graphical boards faster but may cause rendering er-
rors if used with incompatible hardware.
