How to monitor the FPS?

[Loopan]

Hi all

What do you use to monitor the FPS ingame?

Thank you and have a nice day

Try "MSI Afterburner", that gives you lots of info about CPU/GPU load, Ram usage, etc. and of course FPS

@maximov Is there a way (.lua) to modify the font size and colour of the RCtrl+Pause Stats? Thank you!

For some reason I lost text.

I took Raspberry Pi4 and installed Grafana (frontend in screenshot) and Prometheus (metrics database).

On DCS host I installed the windows_exporter (collects metrics and sends exports it to prometheus) and lua script that collects FPS.

I did imlement LuaExportAfterNextFrame which calculates the FPS after at least 4 seconds.

I can send you the example but currently, since it is work in progress, it breaks SRS connection for some reason (possibly I overrode a function I do not need, or have a syntax error somewhere).

This way I have the means of recording and keeping the performance data for longer time, and if necessary compare the performance.

local start_time = nil
local fps_counter = 0
local file_path = "C:/Users/XXXXw/Saved Games/windows_exporter/textfile_inputs/dcs.prom"

function LuaExportStart()
	-- on startup open export file
	start_time = LoGetModelTime()
end

function LuaExportStop()
	-- on stop, close the export file
	export_file = io.open(file_path, "w")
	export_file:write("# HELP dcs_fps DCS frames per second\n")
	export_file:write("# TYPE dcs_fps gauge\n")
	export_file:write(string.format("dcs_fps %.2f\n", 0 ))
	export_file:close()
end

function LuaExportBeforeNextFrame()
-- Works just before every simulation frame.
end

function LuaExportAfterNextFrame()
-- Works just after every simulation frame.
	local end_time = LoGetModelTime()
	fps_counter = fps_counter + 1
	local interval = end_time - start_time
	if interval >= 4.0 then
		export_file = io.open(file_path, "w")
		export_file:write("# HELP dcs_fps DCS frames per second\n")
		export_file:write("# TYPE dcs_fps gauge\n")
		export_file:write(string.format("dcs_fps %.2f\n", fps_counter / interval ))
		export_file:close()
		start_time = end_time
		fps_counter = 0
	end
end

function LuaExportActivityNextEvent(t)
	return t
end

As seen it writes metric in the file, which is later read by windows_exporter, and exposed via HTTP interface toward prometheus.
