+**-lowlatency**
+
+ This tells MAME to draw a new frame before throttling to reduce input
+ latency. This is particularly effective with VRR (Variable Refresh Rate)
+ displays.
+
+ This may cause frame pacing issues in the form of jitter with some
+ systems (especially newer 3D-based systems or systems that run software
+ akin to an operating system), so the default is off (**-nolowlatency**).
