I have a geforce 6600gt vga card, and when i enable the hw vertex processing option at the advanced settings, the game has a lot of graphic bug. anyone know what causes this problem and how can i solve it? :\

Do you have the latest Catalyst drivers? I played the game on a 6600GT, and the only bug I encountered was a serious drop in framerate when having the water quality at medium or high settings (which unfortunately can't seemed to be solved).

i have never installed catalyst drivers, because i have never had an ati vga... I use Z-Tweaked 82.12 nvidia driver...

I set the water quality to high, and i had playable frame rates, when the hw vertex processing was turned on, but graphic issues appeared. disabling the hw vertex processing causes unplayable frame rates...

sry for my english, maybe its not so good

My mistake, I meant Forceware drivers. Have you already tried to use the official drivers?

Official drivers are worse than tweaked drivers

now im downloading a patch for the game, i hope it will solve the problem

hmm, it looks as i have a pre-patched version of the game...

Tweaked drivers are usually less compatible with games.

i dont use the tweaked driver just for fun... i experienced its better for the games. maybe neither, if i see beyond good and evil... if the new forceware come out, i will try again to play this game.
