 Notice how the resolution values double for all values lower than 3. When the resolution value reaches 3, it is increased by steps of 2. Generally speaking, this means that the model detail halves whenever CPU load doubles. For lower details, declination in detail (and thus CPU load) decreases exponentially. Notice how the resolution values double for all values lower than 3.

-If you have a vertex count that is very different from the BIS values, you can try to estimate a fitting resolution value for that LOD. Remember that more vertices = lower resolution value. +If you have a vertex count that is very different from the BIS values, you can try to estimate a fitting resolution value for that LOD.

 For resolution values under 3, you should halve the resolution value each time you double the number of vertices. For resolution values over 3, subtract 2 each time you double the number of vertices. Performance-wise, lower resolution values increase system performance. For resolution values under 3, you should halve the resolution value each time you double the number of vertices.
