;Water reflections([[Wikipedia:pixel shader|pixel shader]] effect)
:Choose from "Mone", "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 at least) and a good CPU (AMD Athlon 2000+, 2GHz P4). It has a great effect on performance, turning it on will use a lot, but with a good comp it only gives a small drop in performance and it does make the water look nice.
:Choose from very low, low, normal, high. Set to normal, the difference in performance from low to normal is minimal, and in a cave you don't need great performance mostly. Even set to the highest does not drop your performance too much. If you find your cave looks to ''spiky'', set it to very low for flat walls.
;Shadows([[Wikipedia:pixel shader|pixel shader]] effect)
:Set this to none for a great performance increase. Setting this to the highest setting will cause the client to render everything twice.
;Render cloud shadows([[Wikipedia:pixel shader|pixel shader]] effect)
:Turn this off for a noticeable performance increase.

;Render bloom ("glow", [[Wikipedia:pixel shader|pixel shader]] effect)
:Set to OFF for performance. Very pretty, makes the game look great, but has a large effect on performance. Makes the game look...well, more lifelike, look at the sun and you will not see much :P ''The effects of this option depends greatly on your hardware (some users may experience a heavy performance drop, some close to none)''.
;Pretty weather
:Have OFF for performance. Performance will drop a great deal when it starts to rain, but on will make weather (mostly fog) look nicer(but more annoying), but weather is really nice anyway so it´s up to you.
