What do I have to set everything in OBS to be able to record Minecraft with 1080p and 60fps? If I want to record Minecraft or any other program, the video quality is very bad, but the processor is not overloaded, since OBS tells me that only a maximum of 3% of it is charged, so it must be due to the settings. And I've already set 60 FPS and 1080p
You should of course have set 1080p in Minecraft, and own a 1080p screen.
Under File> Settings> Video all set to 1920x1080P, and below 60 FPS set. Everything would have to go.
If it still does not work, then play around with output at the bitrate. At present, 3000 are set for me.
That only a maximum of 3% is used by him,
You have probably chosen the right settings. And be glad that OBS eats only 3% with you, with entry-level devices (Ryzen 5 1500x and RX 570) it is 7% with the same requirements.
What bitrate do you have that must be high mind. 8000
