Examples

Use sleep to cap FPS at 30 (in 0.7.2 or older)

function love.update(dt)
   if dt < 1/30 then
      love.timer.sleep(1000 * (1/30 - dt))
   end
end

More sophisticated way to cap FPS (in 0.7.2 or older)

This takes into account the time spent updating and drawing each frame.

function love.load()
   min_dt = 1/30
   next_time = love.timer.getMicroTime()
end

function love.update(dt)
   next_time = next_time + min_dt

   --rest of function here
end

function love.draw()
   --rest of function here

   local cur_time = love.timer.getMicroTime()
   if next_time <= cur_time then
      next_time = cur_time
      return
   end
   love.timer.sleep(1000*(next_time - cur_time))
end
