Just tested RickRuski's recommended setups and installed the new NV drivers.
The SLI setup is much smoother now!

Although I have only recently gone Sli I feel that I have found some things that help to get it running reasonably well.
(1) make SURE that all settings are the same in all adjustments (control panel, Invidia Inspector, etc) sometimes I have found that they aren't.
(2) Try and get all cards balanced so that voltages, frequencies, etc are the same. ( I use EVGA precision Tool for this purpose available at EVGA , my two cards are from different stables and therefore not the same clocks etc.)
(3) Overclocking sometimes has a negative effect (although my cards are factory O/C I have turned them down to stock settings and find them more stable)
Hope these few things that I have found during testing help others who might be struggling.
Here are my new "Profile" settings applied after 285.27 beta driver.
Sli compatibility bits (DX10) 0x00000011
Sli compatibility bits 0x00000011
AA-mode override any application setting
AA-setting 2x (2x Multisampling)
AA-Transparency Multisampling Enabled
AA-Transparency Supersampling Off/ Multisampling
Text filtering-Anisotropic sample opt. OFF
Text filtering-Negative LOD Bias Clamp
Text filtering-Quality Quality
Text filtering-Trilinear opt. OFF
Max pre-rendered frames 3
Multi-display/mixed-GPUacceleration Single display performance mode
Power management mode Adaptive
Treaded optimization Auto
Triple buffering OFF
Vertical Sync Force on
Sli : -
AA-SliAA AA MODE SELECTOR SLIAA ENABLED
Number of GPU's to use Sli SLI_GPU_COUNT_TWO
NVIDIA predefined No.GPU's SLI_PREDEFINED_GPU_COUNT_DX10_TWO
NVIDIA predefined No. GPU's SLI_PREDEFINED_GPU_COUNT_TWO
NVIDIApredefined SLI mode DX10 SLI_PREDEFINED_MODE_DX10_FORCE_AFR
NVIDIA predefined Sli mode SLI_PREDEFINED_MOED_FORCE_AFR
SLI rendering mode SLI_RENDERING_MODE_FORCE_AFR
Other : -
Do not display this profile in the C/P CPL_HIDDEN_PROFILE_DISABLED
Enable application for Optimus 0x00000011 (Il-2 Sturmovik: Cliffs of Dover)
Now have smooth play after cards reach operating temps.
Get EVGA "Precision" tool to show fps and card temps, also to balance frequencies and voltages. These will display on screen instead of using "Fraps".
