Suggestion: For a diver:
When you are in prone position, you will go from swimming to prone position.
When you are in crouch position, you will go from swimming to crouch when the water gets shallow enough.
When you are in stand position, you will go from swimming to stand position when you get to the shore.

Optional: you might wanna add an position icon/picture to the HUD, for when you wanna move from water to land as a diver (maybe only regular mode)

These din't work sofar, still give d3d-errors.

5. Try disable VSYNC.
6. Try set shadows quality to Standard

Update: After 10 days, i still get random D3D errors and sometimes the game just freezes. Few times i've played for more then 2 hours. Mostly play online.
I've no clue what causes this, a memory leakage?

Is there someway to find out, activate more loggings?
