Application Startup
Show Splash Screen
Determines whether the application startup screen appears each time the application starts.
Use Only Certified Plug-Ins
Ensures that only Adobe-certified third-party plug-ins are loaded. The notation Currently
in Certified Mode indicates either Yes or No depending on its status.
Check 2D Graphics Accelerator (Windows only)
(Appears only if your computer hardware supports 2D graphics
acceleration.) When selected, allows hardware acceleration usage when the first document is opened. When
deselected, hardware acceleration usage starts after the first document is opened. This option can slow startup time, so
it is unselected by default.
Note: This option is available only when the option Use 2D Graphics Acceleration in the Page Display preferences is
selected.
