6.5 Video settings
The following right-button menu items control the video output.
On emulators that include two video chips (like x128
)
all options exist twice, once for each chip.
-
“Video Cache” enables a video cache that can speed up the emulation
when little graphics activity is going on; it is especially useful when
you run the emulator on a networked X terminal as it can reduce the
network bandwidth required. However, this setting can actually make the
emulator slower when there is little graphics activity and the amount of
work needed to maintain the cache is greater than the amount of work that
would be wasted by not using it (if any).
-
“Double Size” toggles double-size mode, which makes the
emulation window twice as big. It also selects a more accurate CRT emulation
renderer with scanlines.
-
“Double Scan” toggles double-scan mode, which causes the
emulator to draw only odd lines when running in double-size mode (this
saves some CPU time and also makes the emulation window look more like
an old monitor).
