I used to get super good fps while streaming (capped 240), but I switched to a 4:3 resolution and now, when I have obs (streamlabs obs to be exact) open in the background, the game is smooth at first and then all the sudden drops to 10 fps. When I close obs, it doesn't fix, I have to manually restart the game to fix it. How can I stop this lag? I have a good enough pc for sure, considering my old streams in full 1080p60 were smooth at butter. Thanks in advance.
