I always though that my GPU was in 100% use when rendering with OpenCL, because it can render twice as fast when compared to my 6-core CPU. However, today I discovered that it sits in ~50% usage when rendering, no matter the scene. Also, it doesn’t even activate it’s boost clock.
Why does this happen? Does the same happen with NVIDIA GPU’s?
My hardware:
AMD R9 270X
16 GB 1866 MHz HyperX
FX-6300 - OC @4.4 GHz
Windows 10
Catalyst 16.7.3
Moved from “General Forums > Blender and CG Discussions” to “Support > Technical Support”
If it’s any help, my MSI GTX970 works flat out rendering using the Nvidia driver and CUDA on Ubuntu, I cannot comment on Windows, I haven’t used Windows for more that 8 years now, preferring Ubuntu for my server and Mac for everything else.
Cheers, Clock.
Thanks. I just realised that it depends on the scene itself. This scene only stresses 50% out of my GPU, but the one of the BMW stresses 100%.
Hi, did you use big tiles for render?
OpenCL like it, try one tile for example.
