0 - 100 % GPU spikes when mining [NVIDIA GTX 750 TI]

Question

when I start mining using XMR-Stark my GPU (GTX 750 TI) is showing weird 0-100% spikes like this: Task Manager, GPU-Z.

My CPU (i7-4790K) is consistent: Task Manager.

My hashrate (cpu+gpu) is consistently around 400 and my GPU temperatures are fine: HWMonitor

The only solutions I found when googling were to change the settings in the NVIDIA Control Panel to maximum performance but that didn't help.

I am not overclocking my CPU nor my GPU. I am using the latest GPU drivers, latest Windows 10 version, and latest XMR-Stark version.

Does anybody know how to fix this (and possibly increase my hashrate)?

Thank you

have you tried using a different miner to see if it's causing the problem? — Joss Bird, Dec 29 '17 at 19:23
@JossBird yes, I have tried using a different miner but same result. https://i.imgur.com/KkFNYJy.png — wiu9ahsduuh, Jan 01 '18 at 03:09

You must open nvidia.txt (a file that xmr-stak creates after running for the first time) and set bsleep and bfactor to something other than the default "0". Try "bfactor" : 8, "bsleep" : 25, then restart xmr-stak.

I tried "bfactor" : 8, "bsleep" : 25, but now the GPU usage only goes up to 12% and still has spikes to 0% – wiu9ahsduuh Jan 07 '18 at 15:14
