   I am trying to convert my png files for my particles to pvr because the performance increase in awesome but I must not be converting them right. They all are coming out as squares and not the shape I intended. I tried Conveter_PVR tool which uses the texturetool.

   Thoughts?

   let me get more specific. I am trying to optimize my game as I am starting to see slow downs at weird parts of my game that I would not expect. I have tracked it down to being the particle effects I am using. I want to use pvr's to see if this helps me.

   This would mean though that memory is an issue but I don't see any huge spikes in memory or any memory errors or warnings. I could be missing it. There are so many areas I could be optimizing. I tried to alter my particle system using zombie's technique of reusing particles but I had to back off and go for the low hanging fruit. I like it though and I wonder why if it will be incorporated into cocos2d.

   Any thoughts on this matter would be awesome. Thanks

   I took the fire.pvr from 8.1 and it also is coming through as a square on the simulator. I should have mentioned I was seeing this on the simulator and not tested it on my ipod.

   -- tested
   Still coming through as squares. Like the blank areas are being drawn too.

   Does the particle test (the one that comes with cocos2d) show blank squares too ?

   I tried the particle test and the fire.pvr works but when I put my stars2.pvr it does not. Also I grabbed the fire.pvr the test was using and it still comes through as blocks.

   Ideas? I can't see what the difference is and what I am doing wrong.

   Ok, I when I grabbed the fire.pvr from the cocos2d images I thought it had not worked but it did. So that means my conversion of stars2.png to pvr did not work the way I thought it would.

   What is the best way to convert png's to pvrs?

   When I tried it on my iPod it was squares. Now the simulator works fine with fire.pvr but my iPod does not.

    I found out what my problem was. It was with the conversion of the png itself. I used PowerVR's pvr convert tool and they came out awesome and worked both in the simulator and my device.
