Ogre 1.8 rc in Gamekit - GLES2 rendering slow

Post by j1230xz » Tue May 21, 2013 10:30 am

I am using gamekit to build a game targeted for Android. It uses Ogre 1.8 rc for the Android build. I have noticed that the rendering is too slow. I am having 36000 polygons on stage and 12FPS on Samsung Galaxy S (the first one). Also I have noticed generally slower rendering on OpenGL in contrast to DirectX (like more than 10 times slower). Am I doing something wrong or is there some issue with GLES2, or in that manner generally with OpenGL rendering.

Thanks,
N.

Update:

What would be the expected polygon count on Samsung Galaxy S to achieve 30 FPS? Consider simple scenes.

Thank you

I don't think polygon count has much to do with it actually. Can you turn on the stats and see how many batches are being rendered?

Thanks DanielSefton.

I did and found out that the characters made by designers consisted of many objects thus increasing the batch count. Once the designer set the object as a single mesh all went good.

Thank you again
