support PhysicsX and/or Havok?

[mondo]

I've played most of the supported games with PhysX with and without a PhysX card and there is little noticable difference other than some added visuals like bits of debris.

I bet if they do put in support for any third hardware physics engine (bare in mind Oleg and Co have created there own physics engine for IL2 and were using facets of it in the updated flight engine for some time now) it won't be core to the game so I wouldn't worry. Given that users who don't have PhysX hardware will make up the majority of those who play the game I'd expect the load to be taken on the CPU like the current IL2 engine does.
