Debugging performance issues

If you want to report a vanilla game performance issue, please supply the following info

• The type of lag: Overally low framerate, short or long lag spikes?
• Is it Client or Server lag: If on client the framerate will be low or the screen will be frozen. If its server lag you might get a disconnected icon on the top right corner, have blocks reappearing or animals not moving

If its client lag

• Whats the framerate and fps graph look like? (hit CTRL+F3 to see)
• Whats your graphics settings and what graphics card and RAM capacity do you have?
• Whats the current memory usage? How long have you been playing? Is it single player or multiplayer?
• Make a screenshot of the frame profiler output (hit CTRL+F10 to toggle). You can also type the command .edi to get additional frame profiler output.
• On just individual lag spikes, please run the command .debug logticks 40 let it run for a while and then send us the client-main.txt, it's found in %appdata%/VintagestoryData/Logs
