Did you do any profiling yet to find the hotspots in the interpreter?

Comparison with v2.2 is even scarier:

this is a lot even between 2.2 and 2.3 there is half performance lost.epilectrolytics wrote: ↑Fri May 01, 2020 9:06 am Comparison with v2.2 is even scarier:

Re: v2.3 Vs v2.4 performance
Here are results with GTX970 (2.3 vs. 2.4 build 20200430.12):
On this card CUDA underperforms OpenCL quite a bit...
Anyone else with this or similar GPU series can confirm?
P.S. With the very latest build, LuxCoreUI exits without any error message while evaluating PhotonGI best radius:

Re: v2.3 Vs v2.4 performance
A 970 GTX can not be 7 times slower than a 2070 RTX
Re: v2.3 Vs v2.4 performance
Indeed! I dont' understand if it can be something broken on my system or not...
I tested both with Azure-built and self-built binaries, results are the same.
Re: v2.3 Vs v2.4 performance
I should have fixed this problem.
