Is it more efficient to handle square textures over rectangular textures on modern graphics hardware or does it not matter? e.g. is 512x512 generally better than 2048x128? Thanks

I can't say for sure, but I'd be very surprised if it was more efficient to use square textures. Using power-of-2 textures will probably make a difference, but I doubt using square ones will.

If in doubt, knock up a quick test program to use a 512x128 texture and a 256x256 texture and see [smile]

Thanks, Steve. It's all in the name of efficient and non-memory wasting texture atlas research! :)
