I've installed version 2.79.4 and it is a bit slower than 2.79. I render with GPU 980TI, and the same scene with the same settings (opened and rendered without any changes).

  • Older - 1000 samples, denoiser, 2K res - 3:45min
  • Newer - 1000 samples, denoiser, 2K res - 4:00min

Am i missing something? Or should i turn on or off something? It's not a big deal, but 15sec is about 6% slower. Just asking

Thank you in advance!!

With the amount of changes that happened between versions, I am not surprised at the performance difference.

Blender 2.79a also switched from CUDA 8 to CUDA 9, which Could be slightly slower on older generation hardware.
