Changes

;Water reflection

:Choose from None, "Sky only", "Sky and terrain", "Sky, terrain, and trees", "Almost everything". Have set to NONE unless you have a semi-old card (FX5600 or better atleast) and a good CPU (AMD athlon 2000+, 2GHZ P4). It has a great effect on performance, turning it on will use alot, but with a good comp it only gives a small drop in performance and it does make the water look nice.

:Choose from Extremely Sparse, Sparse, Normal, Dense, or Extreme. Have this set to Extremely Sparse. It makes it much prettier, but you also have a harder time finding anything on the ground, unless it is on/in Dirt, road, water, rock or sand. Large performance drop if used.

;Tree Render Distance

:With newer graphics card that supports it, this will make waves on water and make it look much more real and nice. If this gives you problems or you have a very slow computer, turn it off for a small performance gain.

;Use VBO if available

;Fast Yield

:If turned on you can get a performance gain, but you can also have trouble writing and moving your mouse in-game, if no keyboard or mouse lag, have it on.
