Fixed bug 1338 - Direct3D renderer should set D3DCREATE_FPU_PRESERVE for not behaving vastly different on doubles (causes 3rd party lib crashes!)
Jonas Thiem 2011-11-29 12:28:02 PST
Direct3D renderer should set D3DCREATE_FPU_PRESERVE for not behaving vastly
different to OpenGL/software rendering on doubles and break some libraries
really badly.
Most notable affected example: Lua, which does the most unpredictable things
which are really almost impossible to debug/find out for beginners who never
heard this culprit exists.
Since I believe all renderers should behave the same on that doubles simply
work as expected in a program, this should really be changed! (also this wasted
a few days of my life wondering why everything in my program was so broken)
