I have finally managed to get the demos compiled and running. However, I find the demos are incredibly slow. While I know that the configuration of my system isnt really state of the art to say the least, I'd expect them to run faster than an FPS of 0.5 (yes, 2 SPF rather
) on average.
Has anyone else had such problems? Or is this expected for rigs of the following configuration (because processing real time Physics is expensive, maybe)?
AMD Athlon(tm) 64 Processor 3000+ (2 GHz - single core)
1GB DDR2 RAM
NVidia Geforce 6200 AGP

make sure shadows are disabled in the demos

tuan kuranes! You just made my day. You were spot on about the shadows slowing down the app.
What I did was change shadowtype to none in OgreBulletListener.cpp as follows:
/******************* CREATESHADOWS ***************************/
#ifndef _DEBUG
mCurrentShadowTechnique = convertShadowTechniqueToInt(SHADOWTYPE_NONE);
So now the demo runs fine (60 FPS
). However on exit, I get a weird SIGSEGV. Here's the trace. I'll be stepping through code to get hold of the offending line... it might just be something do with my case. Any hints ofcourse would be appreciated.

Again... its such a relief to be able to get back to work after being stonewalled with the FPS for 2 days. Thanks a ton!
