Purple/Black Checker Issue.

Certain guns (i.e. pistol/magnum) and toxic water, and water when im inside.
All of those listed above is seen as purple and black checkered pattern.
Some thing weird about the water is that when im out side and stare down at the water, everything is perfect. However when my body is physically inside of the water, whole screen turns to purple/black checkered.
Something like this: https://img31.imageshack.us/img31/897/gmflatgrass0001.jpg
I dont mind them seen as purple black, but especially water stops me from advancing the mission.
I heard that it has to do with some textile issue but i dont know how to sort it out.
Please help asap thanx.

Or i could just redownload the game, but im afraid my saves will go away.
Anyone knows where the Save folder is ?

Put this in the launch options.

-dxlevel 90

That should fix it.

Hey, thanx man !

Hi, I had this problem, No fx, just squares and underwater etc a purple checkboard pattern, the way I solved it was go to nvidia control panel, set physyx config to nvidia from default, restart game. Worked for me.
