<marquee>Low FPS with daylight Water!</marquee>

hi guys,
I’m using the Daylight Water in my project, but I noted, that everytime that the camera come close to water, the FPS stay so slower. Withou this object, the FPS is arount the 25~30, whit this object, down to 13~15.

Have some other way to solve this? I need use water fx just in a little part from my scene, but I can with this problem.

Thanks

Which graphic card do you use? maybe it doesnt really support the water FX and it switch to software renderer?
