Dropped Frames when 4K 60Hz AV1 Streaming to YouTube

Hello, I am a 'Starcraft Remasterd' YouTube streamer living in Korea (ISP : KT)
From on 2024.02.07 I encounterd a problem on bitrate goes to virtually 0 issue (100kbps or below) and frames go to 0 litteraly.
Before than I did not encounterd a single problem almost a 1 yaer.

<My previous streaming setup>
- encoder : AV1/HEVC hardward encoding NVENC (using 4070Ti)
- bitrate : 30,000 kbps (30 Mbps)

The problem can be solve to set bitrate down to 10,000 kbps (10 Mbps) but the video quality dropped significantly due to that.

I first checked the upload speed on 'speedtest' website by setting destination to 'San Diego" it was normally 100Mbps level which is way over my previous settng numbers.

So just in case I checked the GPU side by encoding videos and it was okay with both AV1/HEVC.

Before I expreience this, I have not updated any programs including windows and any hardwares(routers, ISP plan etc) since the last time use.

My first speculation was ISP is restricting uploading speed on YouTube, becauase I heard that Korean ISP should pay a lot of money to forerign ISP when I uploaded/downloaded a lot, and due to I am a streamer I usually use 150GB per day in total.

So I contacted them but they said they have not resctrict my internet service.

I really hope to know the reason, of course if possible, the solution. So If you have any ideas about my currenly situation, it would be very thankful if you leave any replays.

Thanks.

Hi, I'm sure you have probably found a solution by now - although I wanted to leave a reply here in case anyone runs into a similar issue (I ran into this post myself while looking for solutions).

For me personally what fixed the issue was turning off the nvidia overlay completely (especially if you're testing out the new nvidia app), other than that turning on hardware-accelerated gpu scheduling in windows settings might fix the problem if you're encountering stuttering without having dropped frames.

Hopefully this helps!
