Hi All, I decided to start a new clean thread here, so people can find what they need to build FG to perform.
As we know, using the CMAKE command: cmake -i . produces a question/answer type script so you can build as a 'Release' and configure any optimisations to suit. Using: ./configure CXXFLAGS= -O3 ... will build Simgear/FG with similar optimisations. Today I tested again OSG, and there are two options that made me wonder - so I turned ON to use a float matrix rather than double: //Set to ON to build OpenSceneGraph with float matrix instead of // double. OSG_USE_FLOAT_MATRIX:BOOL=ON //Set to ON to build OpenSceneGraph with float matrix instead of // double. OSG_USE_FLOAT_PLANE:BOOL=ON Oh my!!! Again a huge increase in performance on my lowly 1.2GHz machine. For the first time ever I saw 60fps+ today... three weeks ago I was lucky to see > 35fps. This gets better and better...
