# Maximum file size (in KiB) IDE should provide code assistance for.

# There are two possible values of idea.popup.weight property: "heavy" and "medium".

# Experimental options that do a number of things to make truly smooth scrolling possible:
#
# * Enables hardware-accelerated scrolling.
#     Blit-acceleration copies as much of the rendered area as possible and then repaints only newly exposed region.
#     This helps to improve scrolling performance and to reduce CPU usage (especially if drawing is compute-intensive).
#
# * Enables "true double buffering".
#     True double buffering is needed to eliminate tearing on blit-accelerated scrolling and to restore
#     frame buffer content without the usual repainting, even when the EDT is blocked.
#
# * Adds "idea.true.smooth.scrolling.debug" option.
#     Checks whether blit-accelerated scrolling is feasible, and if so, checks whether true double buffering is available.
#
# * Enables handling of high-precision mouse wheel events.
#     Although Java 7 introduced MouseWheelEven.getPreciseWheelRotation() method, JScrollPane doesn't use it so far.
#     Depends on the Editor / General / Smooth Scrolling setting, remote desktop detection and power save mode state.
#     Ideally, we need to patch the runtime (on Windows, Linux and macOS) to improve handling of the fine-grained input data.
#     This feature can be toggled via "idea.true.smooth.scrolling.high.precision" option.
#
# * Enables handling of pixel-perfect scrolling events.
#     Currently, this mode is available only under macOS with JetBrains Runtime.
#     This feature can be toggled via "idea.true.smooth.scrolling.pixel.perfect" option.
#
# * Enables interpolation of scrolling input (scrollbar, mouse wheel, touchpad, keys, etc).
#     Smooths input, which lacks both spatial and temporal resolution, performs the rendering asynchronously.
#     Depends on the Editor / General / Smooth Scrolling setting, remote desktop detection and power save mode state.
#     The feature can be tweaked using the following options:
#       "idea.true.smooth.scrolling.interpolation" - the main switch
#       "idea.true.smooth.scrolling.interpolation.scrollbar" - scrollbar interpolation
#       "idea.true.smooth.scrolling.interpolation.scrollbar.delay" - initial delay for scrollbar interpolation (ms)
#       "idea.true.smooth.scrolling.interpolation.mouse.wheel" - mouse wheel / touchpad interpolation
#       "idea.true.smooth.scrolling.interpolation.mouse.wheel.delay.min" - minimum initial delay for mouse wheel interpolation (ms)
#       "idea.true.smooth.scrolling.interpolation.mouse.wheel.delay.max" - maximum initial delay for mouse wheel interpolation (ms)
#       "idea.true.smooth.scrolling.interpolation.precision.touchpad" - touchpad interpolation
#       "idea.true.smooth.scrolling.interpolation.precision.touchpad.delay" - initial delay for touchpad interpolation (ms)
#       "idea.true.smooth.scrolling.interpolation.other" - interpolation of other input sources
#       "idea.true.smooth.scrolling.interpolation.other.delay" - initial delay for other input source interpolation (ms)
#
# * Adds on-demand horizontal scrollbar in editor.
#     The horizontal scrollbar is shown only when it's actually needed for currently visible content.
#     This helps to save editor space and to prevent occasional horizontal "jitter" on vertical touchpad scrolling.
#     This feature can be toggled via "idea.true.smooth.scrolling.dynamic.scrollbars" option.
#---------------------------------------------------------------------
#idea.true.smooth.scrolling=true

# Change to 'enabled' if you want to receive instant visual notifications
# about fatal errors that happen to an IDE or plugins installed.

idea.fatal.error.notification=disabled

Updated MaxGCPauseMillis to 2 seconds because that's really not that long and will rarely happen anyway except on very large projects.
