Profiler graph

This article is incomplete. Please help expand this article to include more useful information.

The profiler graphs show the performance of Luanti in a more detailed fashion. This information is useful for engine developers. The profiler graphs are shown when you hit the debug key (F5 by default) twice.

The following graphs are available:

• rudp_rtt: ???
• rudp_jitter: ???
• packets_lost: ???
• num_processed_meshes: The engine generates geometric meshes from MapBlock data for drawing. This is the number of those meshes that finished generating in each frame.
• mainloop_sleep: If the game runs at a faster rate than wanted_fps, a sleep is inserted into each frame after drawing in order to not consume excess resources; this is that sleep time in seconds.
• mainloop_other: Time (in seconds) spent in each frame for everything else than drawing.
• mainloop_dtime: Total time (in seconds) spent per frame (mainloop_other + mainloop_draw + mainloop_sleep); FPS = 1 divided by this, averaged.
• mainloop_draw: Time (in seconds) spent in each frame for drawing (rendering).
• client_received_packets: Number of received high-level protocol packets in each frame.
