I can add that it has definitely someting to do with compiling with the source code engine vs binary distribution. I just did a cooking process with the binary distribution and the FPS rate is at 60 vs 30 on the source code distribution.
What I can not say is whether this error/warning exists on the binary distribution as well since it does not write any logfile. That’s the reason why I use the source code in the first place so that I can compile it with the flag that writes logfiles on the shipping version.
So it’s possible that it has the same problems just does not print ouot these tons of warnings and therefore is not slowed down by logging. Or it could be that the error does not occur on the binary at all. Without a flag to be set in the binary that turns logging on and off we can not know
