performance too LOW!

[zzz654321]

love2s VS cocos2dx-lua, performance is too low!

What method can solve this problem?

Without looking at your code, it is impossible to tell.

Hmph. I even don't bother. If I'm after performance only, I'd use machine codes.

Löve's performance really depends on what you're trying to do. My experience is that Löve is fast enough to run more or less any 2D game even on crappy netbooks, as long as you code it right. It sounds to me like you're doing something stupid that's destroying your performance.

Or maybe you're running it on a Windows machine with poor OpenGL drivers?

I under android and windows 2003

love2d project: 5000 triangle, ontimer move all triangle
cocos2dx-lua 2.2.5 project: 5000 polygon, animation.

love2d FPS is low.

Some time ago, I read an article about a performance comparison of LÖVE with some other game frameworks, and LÖVE performed slowest among the tested ones. Unfortunately, I don't have the link to the article at hand.

But the important question is: Is the performance only lower than in other frameworks, or it is "too low"? Have you actually tried to make a game and failed because of LÖVE's performance? Or did you just do a test and find that the framerate is lower and in Cocos2d? Because, if LÖVE is slower than other, but still fast enough, then there is no problem.

Do you need that many polygons in your game? Can we see the code you used?

Do you need that many polygons in your game?

Yeah... exactly my same thoughts... real world tests are a better way to test any program. Unless you really need to render a few thousand triangles for your game... What features do you need to be fast?

The answer is probably spritebatches.
