I know many posts were already posted on the topic but... still very unclear for me as I never solved the following issue.

If a texture is directly set in VRAM (not using sceGuCopyImage but directly writing the texture in the VRAM address), is it :
- possible to swizzle it (I was not able..) ?
- if not, what's faster ? swizzled in RAM or like that in VRAM ?

Thanks for any help...

Swizzling is independent of where the texture is. Reading and writing to VRAM should be slower than to main RAM, but rendering from VRAM should be faster. Other than that, you can do it however you want.
