Optimization question

[Alienhead]

Is there a clear advantage to updating and rendering every other loop? Granted speed variables and a few other things need adjusting to compensate. I've recently began experimenting with a controlled rendering loop and have seen some nice results.  I'm just wondering if what I'm seeing is an actual improvement or just the results of 1 frame  updated every too loops increasing the fps.

Here's a short example of what I'm talking about.

 

sets = {}
sets.optimizationlvl = 2


while appquit == false  do

		Time:Update()
		--Render the world
		if rendertick == sets.optimizationlvl then

			-- do 3d

			world:Update()
			world:Render()

			-- do 2d

			context:Sync(false)

		end

	if rendertick == sets.optimizationlvl then rendertick = 0 end
	rendertick = rendertick + 1

end

 

I'm just wondering if I'm wasting my time with this or if this framework could be tweaked in some ways to provide some additional horsepower.

You should not do this.

Fraps actually reports lower fps than LE does when ran without the optimization loop, LE runs the scene at 59 fps while reporting 151. Fraps comes in at 45's - 50's.

I didnt think so.. As mentioned I'm just experimenting but wanted expert opinion.. Tyvm

All you are doing is calling Time::Update twice, in a really convoluted manner.
