Texture Size

[ORI]

Hi, After doing some animation, Im now at the part where Im doing Seambased UVW unwrap to give the many faces of the model the proper texture by UV mapping .,

 I noticed most redemption characters use Texture of 256x256 res but I was wondering if anything limits me of giving a 512x512 texture to it?(since Im making it all from scratch) are there implications on preformance if I choose to do this?

I've made swords that use 512x512 textures and the game seems to work fine, but 512x512 is the MAX.
