Meant to be Seen

Hi. I have got this tomb raider underworld going and it looks fantastic to me. I have a problem thou and cant find a solution to fix it. I am running planar setup on 162 driver with GF7950GX2.
The game looks good in 3d and mostly all is fine exept under water but when i switch on PDA or how you call it black screen apears. Then i decese convergence or separation and it comes back in place (the sonar, messages). Is there any tweak to make it render in 2d? or render it correctly in 3d?. Also what does the enable3dosd function do in reg?
Thanx for looking

I'm not familiar with the nvidiastereodriver but the iz3d driver looks great (1.10b1 or 1.10 b2, NOT 1.10b3 or earlier). There are some flaws in reproduction but no worse than you can stand them. The pda is 2d and the sonarmap is in perfect 3d.
