Lc0 settings for Leela on GPU- Nvidia RTX 2080 Super

[corres]

I'm using T40B.pb from http://data.lczero.org/files/networks-contrib/

T40B.4-160 or -260 are strong nets for a single Ti.
Maybe 42872 is stronger in some situations.
For 2-4 x RTX 2080 Ti J13B.2-188 is even better.

Which of 160 or 260 do you recommend
I usually test setup positions. Often imbalances ones.

To decide this one would made a lot of tests.
I think practically there is no big difference between them.

I now have two indentical cards.

Is demux the best backend for identical cards.

Demux or roundrobin i've been told.

Also is it wise if i copy TCEC settings.
