Yes, for Rainbow Six the higher the better, but the original KeyMander only supports 10K dpi at this time.Set both the mouse and KeyMander to 10K dpi. Also it is important to note that Rg@ has a pretty poor aim/look mechanic and has some issues with low speed movement on long range shots when using ADS. It's the non-linear movement that is built into the game that does this so while we are trying to improve on our end, there isn't a lot we can do to smooth it much more.
