Terrible lag in stages with water

Hello,
Normally, I am able to run PCM on full graphics with my Asus K52SM laptop, however there seems to be a problem in stages with huge areas of water, even with all graphic settings on 0 and "Reflection in water" turned off. While in 3D, the game lag for periods and it ruins the game play totally.
The problem has been noted on these stages:
Milan - San Remo
Tour of Oman, stage 3
... and I also noted in some custom stages I've made with water in them.
I am not the only one with this problem. Take a look at this thread on PCM.daily: http://pcmdaily.com/forum/viewthread.ph ... ost_543272

I expect Cyanide to investigate this issue as it is incredibly frustrating to play a whole stage with lag.
