About a year ago I used OBS to record Minecraft it would record well at 1080p 60 with shaders and everything on full. I tried again to record some Minecraft recently and it was really bad. I tried 720p 30 with bitrate set to 1000 and CPU on ultrafast and it had huge lags. I was getting around 1 frame per 5 seconds. What happened and how do I fix it?
