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)
to solve this problem ,i just updated fedora 20 to fedora 21. may some package update helped me. problem wasn't graphic driver surly!
