Hello Carsten, yep, totally forgot about the mipmaps :D I just set the texture to GL_LINEAR and I got 60 fps! (and still looks good because its not a static texture on geometry) Thanks a lot!
Yes, we are using changelists, but its quite some load on the network each frame.. "works" for small resolutions, meh The best solution I think would be an OpenSG Video Node, and just sync the frame ID, I'll try maybe when I'm on vacation ;) best regards, Victor On Tue, Feb 16, 2021 at 10:49 PM Carsten Neumann < carsten.p.neum...@gmail.com> wrote: > Hello Victor, > > On Tue, Feb 16, 2021 at 4:33 PM Victor Haefner <victor.haef...@gmail.com> > wrote: > >> I use libav and OpenAL, but this should not matter as I decode everything >> in a thread.. >> There I also write the frame data into OSG Images and store them for >> later.. >> >> When I reach a certain frame I set the OSG Image to a texture chunk, and >> my draw time goes up drastically.. >> > > does the time go up only for the frame where the TextureChunk gets a new > Image or for all subsequent frames?
