I have had the same issue. My upload is 5mb, of which I am at 2000 bitrate. When deepbot is up it would drop the frames in OBS even lower than 20%. For me it seems to happen every other update. It started to happen to me randomly one day, as soon as I closed deepbot, i jumped back to 30fps, the green square stayed green even when the fps dropped. If I opened deepbot it would drop the fps again. Then there was an update to deepbot, and it seemed fixed. Then with the last 2 recent updates, the first one, the fps issue started again. Then with the last it fixed it again. I have no idea why it does it. I have tried everything to fix it myself, posted on this forum, but no one knew what to do. But then with the update, all is fine now. Try it again, have you tried recently?
