hi,
As i anderstoud OpenGL and OpenCL use différent driver to process their command on GPU and I wonder how the GPU procees those command. Is there a pin for OpenCL command and a pin for OpenGL command ?
So openCL will use a spécific part of the GPU and OpenGL another part of the GPU. I ask this because OpencL work with matrice and openGL work with vector except is i use compute shader and image.
But using OpenGL it is hard to retreive data to CPU. So i conclude that their are two différent part in the GPU.
Could someone explain how it work on the porocessor.
thanks.
There aren't dedicated parts of the GPU for OpenCL vs OpenGL - they can both use the shader cores / memory etc, and the drivers will use all the shader cores they need, so if the processing is large enough that it can use all the cores, then the OpenCL & OpenGL workloads will most likely go one after the other.
thanks,
But the diuble time processing appends also when using only OpenCL. For exemple using OpenCL alone after 60/100 frames i can go from 63ms per frame to 100ms. Using OpenCL and OpenGL it is from 63ms to up to 200ms.
In this case it isnt a problem of core used. So, it loock like this could be comming fron some where else. It is just my analyze. That is why i asked thequesion.
By the way when GPU start to slow donw the CPU pocesing is also slowing. It look more like mémorie acces problem or heat problem after 60/100 frames.
i did some test today and i foud out that the problem come from the masive use of multicore threading and big data processing. But no idéa why this slow donw the GPU.
