Hi,
i’m working on a project with about 70 small fbo’s (200 x 200 pixel) that i bind to very simple 3Dgeometry (planes) as textures. I’m on a rpi 3b+, 512mb allocated to gpu, raspbian stretch, of 0.10.0. and a very good power supply. I’m getting a framerate of constant 40fps. i’m happy with that. but when i tried to add shaders with ofshader the fps went down to 6fps. if i want to use shaders i initialise the window with gles, like that:ofGLESWindowSettings settings;
settings.setSize(768, 576);
settings.setGLESVersion(2);
ofCreateWindow(settings);ofRunApp( new ofApp());
the shader is a very simple one. If i dont draw all the geometry textured with the fbo’s, oddly nothing changes considering the performance, still 6fps?
Is this drop in performance normal on a pi3b+ or are there any things i can do to optimize things?Thank you very much!
Oli
