No expected impact. If for some insane reason a game is also calling as servers your performance will be improved.
Consider the case of a web page. The content you want (the news article) consists of say 100 get requests totaling 1mb. The content you don’t want (ads) consists of 120 get requests totaling 1.2mb.
When pihole is in use the content you want does not have to contend with adversarial content. You have half as many requests, there’s 50% less data in the pipe, you get what you wanted faster.
Gaming is not impacted because your games don’t call advertising servers. If they did (for some insane reason) the real game requests get served immediately not having to wait in line behind the ad content.
