[GEM-dev] problem to play movies at normal speed with GEM objects

Hello,

I come back with my problem.
I try different option on the nvidia driver (180.44) in the part opengl
settings and antialiasing settings but nothing new. I always get
slowings down on my movies.
They seem to start during long scenes of the movie (no logic here, i
know, but it is what i observe).
Any help ?
