Problems with demos Blend4Web

02 November 2015 21:26
Hello,

I see a slide show when run b4w demos and it: http://eyes.nasa.gov/curiosity/

I think it is because my second video card doesn't run.

Asus K53SV; 8 GB RAM, i3 2.2 ГГц (2 core), Intel HD Graphics 3000; Nvidia Geforce GT 540M (1 GB)

But demos from treejs.com and babylonjs.com works very good. And I don't have this problem when I run desktop games.

Hello and welcome to our forums!

To verify that the issue is connected with GPU switching, try to enforce Nvidia GPU usage, e.g by following the procedures from here. Additionally you may check whether Nvidia card is actually being used.

Also try to measure performance in some other WebGL demos, e.g in the pool demo.

Yes, I switch on second card but this example is a slide show: http://eyes.nasa.gov/curiosity/

My cooler noise.

I try in FireFox and Chrome.

That's strange, how many FPS gives you the following demo?

In beginning: 19-20

In 1 minute: 25-26

I show "Display GPU Activity Icon" and run FPS demo but Activity is None. But I set High Gr. and click on Apply.

This demo works very fine. But Activity is None.
