## Common questions

### Does T-Rex add a developer fee to mining sessions?

Yes. The developer fee is 1%, and 2% for Octopus, Autolykos2, and their dual mining modes.

### How do I choose which CUDA GPUs T-Rex uses?

Use -d or --devices with a comma-separated list of CUDA device IDs, starting from 0. If using Afterburner indexing, --ab-indexing makes IDs start from 1.

### How can I avoid rebuilding the DAG when switching back from a dev fee session?

Set the coin name with --coin, for example etc for Ethereum Classic or etc+zil for Ethereum Classic plus Zilliqa mining.

### Can low load mode be enabled for only some GPUs?

Yes. --low-load can be a comma-separated string that enables the mode only for selected GPUs, such as 0,0,1,0.

### How do I tune T-Rex for LHR cards?

Use --lhr-tune to set the percentage of full speed the miner tries to achieve on LHR cards. The value can be 10 to 95, -1 for auto, 0 to disable, and 74 is a recommended starting value for low power mode.
