Network rendering with RTX on Tweet

[BorisGoreta]

Network rendering with RTX on is giving me brightness errors on the upper left quadrant of an image. Here are the settings on the master computer:

Two nodes are rendering as well.

If I disable the nodes but leave RTX on there are no errors ( only those three GPUs in the master computer are rendering ).

If the nodes are rendering and RTX is off there are also no errors.

Is this a known issue ?

This sounds like some kind of difference while rendering the same scene with the RTX feature enabled or disabled (or a difference while rendering the scene using different GPU architectures). Do you know if the image is the same if rendered with and without this option using your main system only?

Thanks,

Using only master computer the results are correct with RTX on and RTX off.
Using additional render node renders have errors with RTX on but not with RTX off.

Errors appear randomly, every 10 frames on average, could be 2 consecutive frames, could be 40 frames apart. The error appears as dimming of a whole image ( to cca 95% brightness ) or dimming of just upper left image quadrant.

Master is 2080Ti and two 3090.
Slave is one 3090 and two 3080.
