This is a reduced-to-very-essentials version of the old "Advanced Video Control UI" by Xabora.
As the project name suggests,this little mod allow to tweak the spell's particle intensity and to force low quality shaders.
Xabora's mod had a bunch of other features,but given the fact that not all the people are tweak-freaks,i thought to keep it simple and only implement the two most requested features from AoC players.
Once installed the mod you will find the tweaks in the Video options "advanced" panel.
These tweaks can really improve video performances on low-end PCs and the particle density option also improves gameplay when turned to 25% during raids: spells particles will not flash into your face violently anymore XD

follow the readme to install the mod.
have fun,
Aedon

before taking any personal initiative concerning this mod,please send me a PM here or on AoC EU boards,thanks
