FPS problen in GrSim

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)

Solution

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