When i run grsim, fps is about 1! also after put robots or ball,they disappear when touch ground. i use Fedora 20 and tried install ODE with yum. problem is this:
ODE Message 2: mass must be > 0 in dMassCheck() [mass.cpp:49]
ODE Message 2: mass must be > 0 in dMassCheck() [mass.cpp:49]
ODE INTERNAL ERROR 1: assertion "dMassCheck(mass)" failed in dBodySetMass() [ode.cpp:495] Aborted (core dumped)
after a lot search, i found that the solutions are compile ODE, change some codes(in ODEMath.h) and some other. so i recompiled some changed codes and at last grsim lunched(with FPS and robots disappear problem)
with
optirun glxgears
results ,i have no problem in graphic card(output fps is about 60)
