Get FPS and GPU information from my chrome extension.

[Samuel]

Hey guys,

I've created a chrome extension that uses the chrome.processes API which I can use to get various piece of information about CPU usage, memory usage, etc. However, I'd like to use also a google API to get FPS and GPU info (I know I can't get the GPU usage, but I'd like to know what info I could get from my gpu). Is there an API that I can use to get these info? What type of info could I get related to my GPU (using my chrome extension)?

Best regards,

Samuel

GPU articulation is done through WebGL, also referred to as Open-WebGL, it's documentation can be found here: https://developer.mozilla.org/en-US/docs/Web/API/WebGL_API

Thanks, is it possible to get the value of FPS from a chrome API? I know I can use the flag "show-fps-counter", but could I have access to this value via my chrome extension?

No this is not possible, no API exists which allows for fetching such variables.

Then, how is it possible to have this extension: https://chrome.google.com/webstore/detail/fps-extension/gdkkmimldhefhmmmlalioafomdlahcog

You could perhaps use requestAnimationFrame to get an approximation of the FPS. This won't tell you anything about the hardware specifically, but rather what rate the browser is trying to render at.

Thanks for you suggestion. I've developed the following code:

class FPS{

    constructor(){

        let time = new Date();

        this._lastUpdatedTime = time.getTime();

        window.requestAnimationFrame(this.step.bind(this));

    }

    step() {

        let time = new Date();

        let now = time.getTime();

        let FPS = 1000/(now - this._lastUpdatedTime);

        this._lastUpdatedTime = now;

        console.log("FPS", FPS)

        window.requestAnimationFrame(this.step.bind(this));

    }

}

const fps = new FPS();

But in the end, I got something close to 60 FPS, which I think is the frame rate of my display and not from my application (when I use the flag "show-fps-counter" I got something close to 30 FPS). Any suggestion?
