I'm working on a anti event lag system, and i can't simply trust the VX Ace FPS display (F2 in test mode), it sometimes display a FPS of 20-40 while no noticeable lag on the screen, and sometimes displays 50+ FPS with a noticeable lag.

Also, when i uncheck "Reduce Screen Flickering" option (F1 menu in game), the FPS display goes up although no real difference is noticed on screen.

Someone have a idea of how to have a more accurate FPS display?

Use Fraps.

If you want I have a script to display fps on screen :

Code:

module Graphics

  @fps, @fps_tmp = 0, []

  class << self

    attr_reader :fps

    alias fps_update update unless method_defined?(:fps_update)
    def update
	  t = Time.now
	  fps_update
	  @fps_tmp[frame_count % frame_rate] = Time.now != t
	  @fps = 0
	  frame_rate.times {|i| @fps += 1 if @fps_tmp[i]}
	  fps_sprite.src_rect.y = @fps * 16
    end

    def fps_sprite
	  if !@fps_sprite or @fps_sprite.disposed?
	    @fps_sprite = Sprite.new
	    @fps_sprite.z = 0x7FFFFFFF
	    @fps_sprite.bitmap = Bitmap.new(24, 16*120)
	    @fps_sprite.bitmap.font.name = "Arial"
	    @fps_sprite.bitmap.font.size = 16
	    @fps_sprite.bitmap.font.color.set(255, 255, 255)
	    @fps_sprite.bitmap.fill_rect(@fps_sprite.bitmap.rect, Color.new(0, 0, 0))
	    120.times {|i| @fps_sprite.bitmap.draw_text(0, i*16, 24, 16, "% 3d"%i, 1)}
	    @fps_sprite.src_rect.height = 16
	  end
	  return @fps_sprite
    end

  end
end

@Zeus81
