FluidMark 1.1.1 Slower with SLI enabled.

[bbf]

Hello,

I got some strange results on my machine when running Fluidmark with SLI enabled/disabled:

Enabled:


Disabled:


Anyone have a clue why with with SLI disabled it's faster ? That would only make sense if when SLI was enabled, it wasn't using both cards for PhysX, and with it disabled, it was using a card dedicated to PhysX.

GPU-Z info (SLI Disabled):


Nvidia Settings:

Did you enable post-FX ?

I ran it in benchmark mode, so Post-Processing can't even be enabled.

Actually, when SLI is disabled, you must have one GPU for the graphics and the other for PhysX. That may explain why the benchmark gives better score when SLI is disabled.

I will do some tests with a GTX 295.
