Grammar. Beyond that what are you PC specs and what is the mod you're talking about.

This is a cryptic question, what mod was this? If it is a texture mod the number usually indicates the resolution...

The higher number has more detail but will have a higher impact on your game's performance. You could pick both and try them out one at a time to see which one you like the most.

There's a subforum for mods though.

You might want to try to ask in the MOD forum.
