RE: Which parts of DirectX interfere with Lua?

You can use "D3DCREATE_FPU_PRESERVE" when creating the D3D device (the behavior flag).

This will force Direct3D to not change the FPU control word, running the pipeline using the precision of the calling thread.

This is the easiest way to solve this problem, although there might be performance hit to enable this flag.

Subject: Which parts of DirectX interfere with Lua?

Hello:

I've read that DirectX causes problems with Lua because it sets the FPU 
to single-precision mode.  Which parts of DirectX do this?  If I use 
DirectSound but not DirectDraw or Direct3D, will I still have problems?  
Thanks.
