When I am at the driving range and at dusk the R10 does not pick up all the shots and I have the version 4.3. Is this part of the Doppler effect?

No.
The R10 is radar based, and light does not matter at all.
So not sure what issues You're having, but they are not related to light.
If your range has fans or heaters those can have an affect. I’ve used mine in darkness (range lights suddenly went out) and it’s fine.
