Thanks for the reply Borris.
I disabled memory management as you suggested (DisableDriverMemoryManager=true) in enblocal.ini. Just tried the game again, but stil the same thing - 0.6 fps.
But your suggestion got me thinking... So i played around with the memory settings in enblocal.ini and found a solution - it seems it wasnt the memory manager setting that was the issue, it was 'ReduceSystemMemoryUsage' which is default 'true', i changed it to false and this fixed it, now back to normal fps.

I would suggest that this setting be set to 'false' by default, instead of 'true'
Thanks again
