I am using version 4.23.1 from git release downloaded as zip. Compiled in two different machines both with the same Ubuntu 19.04 clean installation.
It freezes between 27 seconds aproximately depends of the complexity of the scene. And got frozen for near 20 seconds. So it is usable in gaps of 20 seconds during 27 seconds of usability. That is very annoying.
There are nothing apparent related in the Logs. I don’t know how to discover what is happening.
I am using Vulkan and an AMD Radeon RX580 with 4GB where it freezes.
And in the other computer an NVIDIA GFX 750 1GB without the problem and with propietary 418.56 drivers.
So, it is apparently an AMD graphics related problem. I am using the open source drivers because there are no radeonpro for Ubuntu 19.04.
There are no CPU use neither GPU use. It is used as normally except when It need to draw everything after the freezes I receive a peak of GPU use.
But when I launch the game in Standalone Game that does not happen in the game.
I adjusted the garbage collector time without success. It appears not to be related.
Edit: As I wrote down, there are 100% CPU use in one core. I have a 8 core processor so that is why I treated it as “normal” CPU use (because average CPU usage was low).
