Here you will run into options that only offer 2 choices, on or off! This is indicated by 2 numbers, 0 = off, 1 = on! Heres a few examples of these types of options...

GRAPHIC_TOWNLIMIT=0 <--- Turn off player sin town, and limit graphics, 0=off, 1=on! this should be set to on for those with low end PCs.

GRAPHIC_RENDERTREE=1
GRAPHIC_RENDERGRASS=1 <--- You can opt to turn rendering grass, and trees to on or off. I opted to have them on by placing the number 1 in each spot. those with low end machines leave off if lag persists.

Thats about it for now. Theres only one left and is the most important setting in the .opt file that needs to be changed in order for your settings to be set for good...

GRAPHIC_PRESETOPTION=4 <--- do not use the number " 0 " (zero)

Once you have everything set from trial and error, save your settings by selecting file at the top left corner of file and choose the "save" option. close out the file and replace the extension to .opt if needed. Fire up rappelz rupees, and enjoy!

If for any reason you messed up your settings or screwed something up, simply delete the file " rappelz_v1.opt " and fire up Rappelz to give you a default setting file again, rinse, repeat! If you dont feel like messing with the .opt file to your specs, you can still choose a decent selection of preset modes and have them work fine till the bug is fixed. Simply select either user modes low,medium,high and save and play. By choosing these preset options you may not get a total 100% settings you like, but still enough to be playable till things can get fixed.

If you want a custom set up file and dont feel comfortable playing with the .opt file(you shouldnt as theres nothing to really screw up,and isnt like you can start over again), VGG Medran has set up a few files to replace your current one if ya feel this is a better route for you, or your just lazy. Good Luck and hopefully this helps some feel they have a little control over their settings till someone with half a brain fixes this, and other craptacular bugs that E4 has gotten.

PS> This is more trial and error for me as much as you. I did find that i can create wider draw distances for everything and still maintain no lag in this game. Those with low end PCs and still getting lag, more than likely your PC isnt cutting it even on low levels, or your connection blows. I used to run this game on a really low end machine of 5+ years old, my connection was even screwed up making the lag worse.
