SLI Problems

[PTK1982]

So i install drivers (158.43) and reboot
Next it detect that i have SLI capable system and wants to reboot again (for shortwhile Nvidia Control Panel is Not responding then ask reboot)
Now appereantly i have sli enabled i go to nvidia control panel put the resolution to 1680*1050 and color depht to 32bits.
Next i go to look 3d settings and i notice that SLI rendering mode is: Single GPU and i cannot change it to Multi GPU mode.
Only options are: Single GPU, Force SFR, Force AFR, Force AFR2 where is multi GPU mode????

My earlier SLI experiences are from win xp 7800GTX sli + 91.47 drivers so is SLI enabling method changed from that time or is something wrong???

Answer for me GURUS!!! THX

Enable Multi-Gpu should be in a different tab...from memory..

To answer my own question:o

It is changed from earlier win xp sli

Global setting is single GPU (appereantly for aero no need to keep both gpu busy) and game profiles are saying how to use sli single or multi.

But this raises second question

Now that SLI is appereantly working in my case how is it possible that i get worse performance in NWN2 than single 8800GTS. Is the SLI still borked in Vista or is it that for NWN2 nothing is enough?
