If you like Misa's and the RPG feel you will love this pack.

What's Changed in this pack:
Custom Rain, specifically made in low res, for those who have issues losing FPS during rainfall.
Changed some of the transparency on the leaves.
Went through some pixels and did some touch-ups for the resolution.
Made some of my own custom textures in the mix.

Changelog

08/11/2011 - 9:20CST: Fixed Rain

Scubavision version:
Based on Misa's 2.2.1 texture structure, mixed with LB Photo Realism/LB RPG Realism 64x & 128x textures.
Also includes textures from Mitchell's HD Texture Pack, and HeroCraft.
Original Artists for minecraft files, which may include some textures in another pack,I don't know
about them to give credit at this time.

Resampled and chomped down some KB's in texture data sizes, reduced nearly all un-necessary colors
helping the drawing time.

Drew a little myself and cleaned up the textures some. Lightened up most of the color.
Lower memory resources needed than Misa brings a higher FPS and faster chunk
loads.

Thanks for giving my texture pack mix a try, I hope it makes you happy and
assists your want for high res textures, but the computer is just too
framed to enjoy Misa.

Additional Notes

I Almost feel bad remixing this and taking any credit, but I did it more for myself... I just noticed performance improvement after I made it. I thought others could enjoy the same and so I'm sharing it. Should be impressed somewhat at least... I hope.

Sorry, I don't have a good way to show all the pictures, best is to try it yourself... Might even be impressed with its performance and look.

In order for this to work with Optifine/Optimine, it must be set to Graphics: Fancy
