GLES2 vs GLES1 overral performance decreased

Postby asktomsk » Tue Jan 17, 2012 5:43 am

Have converted my project to GLES2 (yes it was fkng hard).
Gles1 fps ~ 55
Gles2 fps ~ 40

Time between activities and scenes switching increased at least twice.

Is it OK?

I am noticing a slight decrease in performance in my game as well. All I did was fix the code for GLES2.0.

I also experienced this drop in frame-rate. I'm using a Desire HD and had the same drop as asktomsk.

I've narrowed it down to the colour modifier for particles:

particleSystem.addParticleModifier(new ColorModifier<Sprite>(0.3f, 0.4f, 0.3f, 0.2f, 0.0f, 1.0f, 0.0f, 5.5f));

The simple initialiser seems OK:
particleSystem.addParticleInitializer(new ColorInitializer<Sprite>(0.7f, 0.0f, 1.0f));

Thanks for pointing me towards the particle system!

Edit:
Oh looks like this problem is fixed in the latest version of AndEngine, where "ColorModifier" is now "ColorParticleModifier". Watch out the constructors for the modifiers have had the variables move around, now the time float numbers go first!
Edit:
Latest version of AndEngine doesn't seem to be faster...
