Today i was working on TNT , and my dad saw the HUGE lag after the blow . And he asked " ... again you are plaing yor stupid game ... what is this ... omg why it lags so much , it has 2D graphics , no any cool 3D graphics , its simplest graphics , so why it lags so much ? " (i maybe added something mine) . And i asked myself , why it lags so much ? Why the 2D game needs so much powerful pc to play with no lags ?

Because of the physics calculations of every pixel.

Ok but most of new 3d games have physics , and they arent lag on my pc.

CC lags because of it's physics engine and the ridiculous amount of objects and such.
Graphically, it probably runs fairly smoothly.

CC has an absurd amount of objects, and is RAM intensive, giving it the whole workload.
Most new 3d games and such are graphically intensive; and they can make use of your graphics card for that.

tl;dr CC overworks your RAM

Can you imagine CC with Crysis graphics or something close to that?
Now that would need a super computer!

If it used Source engine, it would run pretty decently I think. CC just isn't well-optimized at the moment.

Using a 3d engine for a 2d game would certainly mean it was well optimized though, right? I mean, 3d is BETTER than 2d.

[/sarcasm]

You don't seem to get it. The source engine typically doesn't run 100s of objects moving and bouncing around realistically at once. It also doesn't have constantly deformable terrain which can also turn into a bunch of little moving, bouncing things when you blast through it. The source engine also doesn't take its player models and make them out of five or more separate objects.

So don't run your mouth about optimization. That really isn't the issue here.

Um yeah, 3D engine with most likely a different scripting language does not work with a 2D pixel graphics game with deformable terrain.

What did you say?

Did I hear optimization, well it is practically as optimized as it can be, the engine is to powerful, my ping rockets on online games because I play it.
This thing is made with godly amounts of 'realism' which is good in this game, because it is being used correctly, not like GTA4.

That was sarcasm notice the head roll smilie? Oh well...

If Cortex Command had WORMS physics it wouldn't lag at all.
But then again, Worms doesn't have physics
And then cortex command wouldn't be fun.

If an engine advertises itself as 3D then buddy, it's got 2D covered.

Problem with this topic is that people think a software graphics engine is like a car engine. It's not. You can't throw a fuel-efficient Source engine or a V8 CryTek engine in CC to make it all better.

It just wouldn't work.

The "engine" data has written up for CC is pretty much the best there will ever be for CC in it's entire existence.

The problem is simple, too many physics calculations for today's technology. Every pixel has to be checked for collision with other pixels, and must determine their behavior based on:

- Impulse force
- Bounce
- Friction
- Priority
- Color
- Will it change color on being knocked loose?
- Collision, of course. Has to check for other pixels (all with this information as well) to determine behavior.
- And.. the perVolume calculations
- Likely more stuff behind the scenes.

This is for EVERY pixel in the game. Which is pretty much everything you see in the game.


The solution is to, of course, optimize the software. I haven't seen the source code behind CC so this is where I stop.

and data says its coming. (the optimisation)
so expect it somewhere within the your lifetime. maybe.

basically, the graphics of a game only mean so much as to how much it lags, and even then the grapical lag will likely be your GPU's fault. the physics in other engines arent nearly as complex as they are in CC, nor are they calculated for every stupid pixel in the scene each frame.

worried about lag? play in editor scene woo.

tl;dr: what everyone who knows what theyre talking about said.

As far as I can tell, CC does not take advantage of multi core processors, or graphics cards. If that ever happens, I think you can expect some big levels and great explosions =D
