Barrel distortion

Mostly for performance reasons.
You are free to use a barrel distortion setup in your games.
Its just not included in the plugin because i have not found a solution yet that will automatically determine if the power of the deviceis big enough and then activate a distorted mode.
i have run some tests and concluded:
Pixel shader based barrel solutions :
pretty slow on 1080p devices
mesh based barrel solution:
runs fine , only too slow on old devices.
are there any other ways to do it without unity pro ?

Thanks for the explanation, I figured as much.
The only thing I can think of would be to incorporate the barrel distortion in a vertex shader and override all materials.
That would deform the final image somewhat, but might be acceptable.
The central area gets compressed so you don't have long edges there.
It would be pretty performant too, I think.
