[TM2] Other - Water flickering in editor and game

[Whitestar]

Hi, I'm experiencing water flickering both when I terraform with water in the editor and when I play.
Even if I use the new 320.49 drivers from Nvidia. I'm running two GTX 670 cards in SLI.

Is this a known bug?

AA or other filtering setting?

Or what kind of flickering is it?

[Whitestar]

It looks like a texture flicker. I am using FXAA. Just remembered I'm using it in both the drivers and the game. Should I try to disable it in one place?
I'll try to provide a video when I get home.

yeah, I also sometimes observed some flickering or strange noise artifacts in the background.
I keep texture and shader quality high, filter settings max 4x (both AA and anisotropic).

Make also sure the settings of the game do match the settings in the video driver configuration where you cannot set them to "handeled by the application".

For some reason the flicker goes away when I set Water Reflection to Medium. Oh well, guess I have to settle for that then.

[TMarc]

Is it perhaps also due to antialiasing? Waves create lots of small moving polygons, so lots of short edges to filter.
And it is known from animations that AA causes some flickering.

Perhaps you could shoot a short movie to show it.

Looks like it's a SLI issue. I tested with and without SLI on 320.49 drivers. Results:

Single-GPU | water reflection Medium : OK
Single-GPU | water reflection High : OK
SLI | water reflection Medium : OK
SLI | water reflection High : Water flickering

Nemesiss, can you confirm?

I know I've said it before, but I WILL post a video.
