      the 3dmark dx12 test causes graphical defects to occur

      in the image below some of the vertex's of objects are not being stored correctly in l3 cache (breaking cache coherence)

      the test works by testing how many draw calls the GPU can handle to help the GPU the same texture is used on all objects
