[Solved] No Physx option with GTX 460 in Batman Arkham Asylum :(

Last week I got a gts450 in order to replay Batman Arkham Asylum with physx - but the bmlauncher.exe settings gave me no options for it.
so i changed the BmEngine.ini code; 'physXlevel=0' to 'physxlevel=2'
Game ran fine but slowed down extremely in phsx bits, and often crashed in areas with cobwebs etc.

SO

I just traded up my gts450 for a GTX460. Which NVIDIA says should run Arkham asylum with physX.
downloaded and clean-installed the latest nvidia drivers
and still I get no physx option from bmlauncher.


(yes that's my doodle in the BG)

So again, I edited the BmEngine.ini as prevoiusly stated
This time, the game crashed while loading my savegame and gave me a smug eff you:

"Couldn't file file for the package A_physX requested by async loading code.
?int?version.ID.Unreal? ?int?version.ID.local> FMOD: 42200/42200 game
BLAH BLAH BLAG etc etc and so on"

The game runs fine without physX on but I WANT MY PHYSX dammit
so what should i do?
And is there some way to test if physx is working at all in my system?
