Longer render times on 2.81 than on 2.80?

[egementncr]

Hi folks,
I searched through but didn’t see similar topic.
I was working on a project and switched to 2.81 immediately when it was released.
After that I noticed that rendering a bit slower on 2.81, especially with the GPU. CPU results are similar although it was slower on 2.81.
I am using Radeon VII and 3700X.
I also did BMW benchmarks on each version.
It took 74 sec on 2.80 and 83 sec on 2.81. (only GPU)
Is anyone else experiencing this issue?
Cheers,

See this topic:

Very slow GPU rendering in Cycles (opencl). Blender 2.81

Greetings! There are problems with rendering on the GPU at 2.81, it is significantly slowed down compared to 2.79 (nightly build) AMD RX 580 videocard [79] 2.79 [ nightly build] [81] 2.81 Last build Other scenes also have a big difference in different versions of the blender. Optimization under Opencl in 2.81 is planned?
