Thanks for your advice, guys. I downloaded and am currently using something called lolminer, like the first person suggested. It works, but the hash rate is very bad. Plus, I can imagine that they are taking some of it for the developer. since it's not a free miner like ethminer used to be.
Nevertheless, I guess it doesn't matter as ETH mining will cease to exist in a couple of days, right?
Russian miners have information about this, I will translate:
The hash rate drops on WIN 10 by 6 GB NVIDIA - install Gminer 3.05, driver version 512.16https://bitcointalk.org/index.php?topic=5408254.msg60663759#msg60663759But since there are less than 18 hours left before the end of ethereum mining, this will not help you much.
