Hi there
i have installed two RTX cards for Leela.
Are there parameters to bring out the best performance for such setup?
Right now I get 60.000 nps - 65.000 nps in console mode after go depth 5000000
But ist different when using leela in a game.
Pretty soon the GPU load is going down to 70% - 80% on both cards.
PSU is big enough, so is this normal ?

Just a guess, but it could be thermal issues, so the gpus clocks go down...

Two RTX have about 500 watts TDP, this has somehow to leave the PC case.

Take a look at this sheet for different LC0 gpu parameters and nps:
For RTX gpus you should use currently the cudnn-fp16 backend, tunebale params are threads, nn cache and batch size for example.
