Difference in FPS between Firfox and Google Chrome

[Dad72]

I used the 'sprites' to make the grass. I must have 1800 sprites on the stage. I note a large difference in FPS between firfox and Google Chrome.
On Chrome, I have 40/41 fps
On Firfox i have 25/27 fps

on firfox, my fps, quickly drop. If I removed the sprites, my fps goes back has 60 on firfox and on chrome. I think that there is a performance problem with the sprites. If i put 4000 sprites, my scene lag, the fps are very low.

I cannot fix Firefox

Ah Ah, recess. But why much difference. I asked if you have an idea of why.

With Google Chrome as well, when it adds a lot of sprites, the fps, down very much. Why?

[GameMonetize]

Too much sprites : 4000 is a lot

[Dad72]

1800 sprites is also apparently much?

 

Therefore, there is nothing in Babylon which permettes to make the herbs on a field in large quantity? The grass allows you to make the scene more realistic. This brings a touch of nature. It is disappointing not to be able to put grass in large quantity.

Are there solutions to put large amount of grass?

[Dad72]

There would be a solution to make large expanse of grass with the sprites. With isvisvible. To hide the herbs at a certain distance from the camera by placing isvisible on false. This would allow a lot of grass. Only 1000 could see, the rest would not be rendered as a camera does not track.

 

This would be has add with the request of here, or you forget to answer me:

For me this should be resolved by a shader and not by sprites

 

The shader has more raw power and is only used on visible pixel. You can use a dynamic texture where you define where grass is and inside your shader you can use this texture to draw grass or not

[Dad72]

Thank you very much for the advice. I have of very poor knowledge in shader, but I am going to try to study question.

[GameMonetize]

look what I did with ground shader in worldmonger demo

[Dad72]

I find the solution.

with google chrome, if I put the object to false isvisible to hide objects far from the camera the FPS remains acceptable.

By contrast with Firefox it must add visibility 0 in addition isvisible false for the FPS is acceptable, otherwise, the FPS are a 16.

 

thus:

 

Google Chrome :

mesh.isvisible = false;

 

Firfox :

mesh.isvisible = false;

+

mesh.visilility = 0;

[GameMonetize]

To be fully removed try to use this: mesh.setEnabled(false)

[Dad72]

Yes, it is perfect, it works well. It is better than what I had done.
