High ping on Windows 8.1?

Question

Windows

The other day I sinned and installed Windows 10 on my computer. Somehow reconciled with the design and began to use it. I wanted to play my favorite zombie mode in black ops. After suffering for several hours, I put 8.1 in the hope that there would be no problems with it at least. So, the question is, because of what there may be an unstable high ping in the game, given that I am the host. According to the results of the measurement in the speedtest, the ping was 2ms, the speed was about 100 Mbps. In the game, the indicator is from 50 to 200. Does it make sense to put sevens, but is there another problem? Changed network driver
