Hi,
I have problem with the TexturePacker:

GameWindow {
    id: gameWindow

    //licenseKey: "<generate one from http://felgo.com/licenseKey>"

    activeScene: scene

    screenWidth: 320
    screenHeight: 480

    Scene {
        id: scene

        width: 320
        height: 480

//        TexturePackerAnimatedSpriteVPlay {
//            id: image

//            source: "../assets/img/image.json"
//            frameNames: "image"

//            running: false
//            paused: true

//            anchors.top: parent.top

//            visible: false
//        }

        MultiResolutionImage {
            id: image2

            source: "../assets/img/image.png"

            anchors.bottom: parent.bottom
        }
    }
}

The performance worsens when I insert the TexturePackerAnimatedSpriteVPlay item, even if it’s hidden. Here are screens from my profiler:
Without TexturePackerAnimatedSpriteVPlay

With TexturePackerAnimatedSpriteVPlay

I am using the v-play logo image:

sd 64×64

hd 128×128

hd2 256×256

One of my image.json files:

{
	"frames": {
		"image": {
			"frame": {
				"x": 0,
				"y": 0,
				"w": 128,
				"h": 128
			},
			"rotated": false,
			"trimmed": false,
			"spriteSourceSize": {
				"x": 0,
				"y": 0,
				"w": 128,
				"h": 128
			},
			"sourceSize": {
				"w": 128,
				"h": 128
			}
		}
	},
	"meta": {
		"app": "http://www.krk-dev.com",
		"version": "1.0",
		"image": "image.png",
		"format": "RGBA8888",
		"size": {
			"w": 128,
			"h": 128
		},
		"scale": "0.5"
	}
}

I have the latest 2.8.5 VPlay lib.

Hi Pawel!

Can you send your test project to support@felgo.com? We will then have a closer look at the performance issue.

Best,
Günther

Hi Günther,
I got such issues even for a dummy project. However I’ve sent you the project as you suggested.

 

Best regards,
Paweł

I can confirm this, I just started migrating to spritesheets for my static images and my fps drop noticably when I use TexturePackerComponents.

 

Edit: Don’t know if it’s relevant, but I’m using Linux.

Hi Spike!

Thanks for your input on this, we will have a closer look at the issue.
On which devices do you have these issues, does it only happen for Desktop Linux or also on your mobile devices?

Best,
Günther

I don’t know about Pawel, but right now I’m exclusively on Deskop Linux. I’m not testing mobile atm.

I’ve sent this by e-mail, but I post it also here for clarity:

• Samsung S4 mini (GT-I9195)
• Samsung Galaxy Tab 4 (SM-T530)
• MacBook Air (OS X 10.9.5, NVIDIA GeForce 320M 256MB)
• PC (Windows 7 x64, NVIDIA GeForce GTX 650 Ti 2GB)

I got worse performance only on my PC. Which is surprising as it’s far more effcient than other devices.

Hi! Any update on this issue? I’ve encountered same problem while testing Texture Packer spritesheets. Fps is around 40 on PC and stable 60 on android device with one animated sprite only on screen.

[GüntherFelgo Team]

Hi Maxim!

We were unable to reproduce the issue with our tests back then. Also, the TexturePacker implementation does not handle Desktop platforms differently from mobiles, which makes it hard to get to the root of the issue.

Do you measure the FPS rate using the profiler only or is the drop also visible when simply showing the fps rate by activating GameWindow::displayFPSEnabled?

Also, which operating system and version are you using for development?
Up until now it seems that only some Windows and Linux systems show the issue.

Best,
GT

Hi Günther!

FPS drop was visible with GameWindow::displayFPSEnabled. I didn’t use profiler.

 

I’m using Windows 10 with Nvidia 1050ti if it does matter. I can see FPS drop even with only one frame in TexturePackerSpriteVPlay.

Hi Maxim,

Thanks for the additional information. As the issue popped up again now also for you we will have more detailed look what could cause this.

We’ll keep you posted on our findings.

Best,
GT
