Ok, still trying to wrap my head around the concept 
But getting there. Hats to those of you here who understand all this
So I got it to run.
1080ti on Windows
Bat file >> Kangaroo.exe -t 0 -gpu -gpuId 0 -ws -w save.work -wi 30 input.txt
Starts off at 200Mkeys/s and then continuously drops
Also why does this algo seem to only work for bit ranges that are multiples of 5?
Glad you finally got it to work. But getting there. Hats to those of you here who understand all thisSo I got it to run.

Now that you finally got rid of the server command, you can play around with the grid size numbers for your gpu, up to you.
The MKey/s drop but shouldn't be that much. I have had 1070s that maintain above 200 MKey/s.
I do not know what you mean by multiples of 5...if you are referring to the puzzle, that's because every 5th address in the puzzle has the pubkeys exposed. This program works by only knowing the pubkey. But the program will work for any range, any "multiple".
