Welcome!

This may be because LOVE, by default, doesn't have a framerate cap; but then again, it doesn't do this on my computer. It could also be because you're doing some heavy duty processing; make sure you're not creating any resources in love.update or love.draw.

EDIT: By the way, what exactly is your avatar doing? I hope it's not what I think it is. :ehem:

You can use love.timer.sleep to slow it down.
Help us help you: attach a .love.

If you're thinking it's wielding a chainsaw, then yeah, that's exactly what it's doing.

How can I set the framerate??

I'm following this tutorial, so I use love.graphics.draw for any drawable object in a table may be this?

He was laughing :joker: , anyway to avoid problems i changed it.

Do you mean in the love.draw() function?

You can't. You can aim for a certain framerate with love.time.sleep(), but it's imperfect.

That particular tutorial has been criticised on this forum. Drawing things shouldn't cause problems like that.

Could you try running LÖVE without a game (you'll get the no-game screen) and tell us whether the same thing happens?

Also, could you upload a .love of your game to the forums, so we can look for clues there?

You can put it there, but traditionally, it's put at the end of love.update().

I'm glad you pointed this out. I didn't realize my CPU usage increases by 500% (from 10% to 50%) when I run my game. It runs at about 325 FPS. I'll give the sleep idea a try.

The best way to attempt to set the framerate, is to redefine love.run and increase the amount of time slept at the end of the function (the love.timer.sleep call). You may to do something like:

Code: Select all

love.timer.sleep(1000 / 60) -- 60 FPS

But, as I said, it is imperfect.

That's the point, drawing two elements every frame shouldnt be a problem.

I tried to run love without games and nothing happened, cpu was fine, but I also tried with a mario version posted by a user, with mario running cpu 100% and the temperature rise up to 90°
