The latest version (7.5 b1) is causing web pages to open 3-4 times slower than when adguard is turned off, up to 30 seconds from me clicking a link to it opening the page ( not including the time it takes to actually load the page) .
It's weird because my browsing experience for the entire 7.4 stable release was super sluggish (may have been a botched upgrade, I didn't uninstall/reinstall) but the upgrade to 7.5 beta 1 resolved those issues.
To do this, find Network and Sharing Center assuming you're using Windows, and you can set your DNS settings there like I have shown below
set your dns server here
If you have ipv6 connectivity you can also set your dns settings there also (ignore my loopback as my ISP still uses ipv4 stacks to resolve ipv6 addresses):
