I tried the PocketTest.zip file and what I found....
thx for your support.
Setting up the project from scratch using recent svn 134, it works using the MSVC 2005 Compiler. On a 400MHz Qualcomm with coprocessor(fpu) PDA, using warmstart ON, positioncorrection ON, 60Hz, 10 Iterations gives about 30-40 % faster executing code using the fixed point compared to the floating point library.
Broadphase fixed 11 vs float 6 fps,
Domino 20 vs 13 fps,
Pyramide (2 rows down) 8 vs 5 fps
I have the impression, that the influence of positioncorrection in the floating point library is remarkable higher on speed than in the fixed point library. Turned off pos.corr., in fixed point lib the pyramide starts with 11 and goes down to 5 fps, in the floating library starts with 8 and goes down to 1 fps (top row is "down") .
... roughly compared
