I have a problem with an app that is slowed down significantly when an openFrameworks based app is launched. Both apps use little cpu and memory, so i don't think there's a bottleneck.
I can reproduce the problem by running
alone compared to
in one console and
glmark2 -b jellyfish
So openGL rendering somehow affects the CPU performance and it is not clear to me why.
Can someone explain ?
(System is Ubuntu 14.04 i7 with intel HD3000, however a system with an Nvdia card showed the same effect)
