A C++ based renderer that uses the Embree ray trace engine. Tungsten does not build on my AMD processor and gives an error of
CMake Error at CMakeLists.txt:39 (message):
The target machine does not support SSE3. At least SSE3 is required
-- Configuring incomplete, errors occurred!
As best I can tell, the code hs an OptimizeForArchitecture.cmake file that has hard-coded a set of architectures that are supported. I see “Zen” listed but not anything newer. So I suspect a bogus check that prevents it from building.
It does run on my Intel CPU so I am able to get the following metrics
