  • The Light Learning scheme— for improved performance is now default. This should improve convergence for scenes with complex setups involving many lights seeing the most improvement. This version is not deterministic and small differences can be seen if not well converged
  • Checkpointing with Deep Data   is supported as well as additional performance options for output. See the documentation for more details
  • Further imporvements to improvements to OSL performance — The SIMD version of OSL is optimized to execute 16 samples at a time with Intel® Advanced Vector Extensions 512 (Intel® AVX-512).  It can also execute using Intel® Advanced Vector Extensions 2 (Intel® AVX2), Intel® Advanced Vector Extensions (Intel® AVX), or Intel® Streaming SIMD Extensions 4.2 (Intel® SSE4.2) at reduced performance levels.
