### Choose `intensity` and `worksize`
-Intensity means the number of threads used to mine.
+Intensity means the number of threads used to mine. The maximum intensity is GPU_MEMORY_MB / 2 - 128, however for cards with 4GB and more, the optimum is likely to be lower than that.
`worksize` is the number of threads working together to increase the miner performance.
In the most cases a `worksize` of `16` or `8` is optimal.
