Available since LÖVE 0.9.2 |
This function is not supported in earlier versions. |
Gets performance-related rendering statistics.
The per-frame metrics (drawcalls, canvasswitches, shaderswitches) are reset by love.graphics.present, which for the default implementation of love.run is called right after the execution of love.draw. Therefore this function should probably be called at the end of love.draw. |

Function
Synopsis
stats = love.graphics.getStats( )
Arguments
None.
Returns
table stats
- A table with the following fields:
number drawcalls
- The number of draw calls made so far during the current frame.
number canvasswitches
- The number of times the active Canvas has been switched so far during the current frame.
number texturememory
- The estimated total size in bytes of video memory used by all loaded Images, Canvases, and Fonts.
number images
- The number of Image objects currently loaded.
number canvases
- The number of Canvas objects currently loaded.
number fonts
- The number of Font objects currently loaded.
Available since LÖVE 0.10.2
Available since LÖVE 11.0
number drawcallsbatched
- The number of draw calls that were saved by LÖVE's automatic batching, since the start of the frame.
Function
Available since LÖVE 11.0 |
This variant is not supported in earlier versions. |
This variant accepts an existing table to fill in, instead of creating a new one.
Synopsis
stats = love.graphics.getStats( stats )
Arguments
table stats
- A table which will be filled in with the stat fields below.
Returns
table stats
- The table that was passed in above, now containing the following fields:
number drawcalls
- The number of draw calls made so far during the current frame.
number canvasswitches
- The number of times the active Canvas has been switched so far during the current frame.
number texturememory
- The estimated total size in bytes of video memory used by all loaded Images, Canvases, and Fonts.
number images
- The number of Image objects currently loaded.
number canvases
- The number of Canvas objects currently loaded.
number fonts
- The number of Font objects currently loaded.
number shaderswitches
- The number of times the active Shader has been changed so far during the current frame.
number drawcallsbatched
- The number of draw calls that were saved by LÖVE's automatic batching, since the start of the frame.
Examples
display the estimated amount of video memory used for textures
function love.load()
love.graphics.setNewFont(24)
end
function love.draw()
-- some drawing code here --
local stats = love.graphics.getStats()
local str = string.format("Estimated amount of texture memory used: %.2f MB", stats.texturememory / 1024 / 1024)
love.graphics.print(str, 10, 10)
end
