Keep "resolution" at 1280x720 for 99% of games (this is why it says recommended) and use resolution scaling instead. 1920x1080 can impact performance and even though games say they support it it doesn't mean they will necessarily render at the full 1920x1080 and if you're using resolution scaling it's useless because we scale from 1280x720 anyway.
