Question / Help Blurry stream (high spec single PC)

New Member
Hello,
I'm trying streaming at 1080p 60fps on Youtube but the stream quality gets very blurry in the middle of the game (when action is heavier).

CPU i9900k
GPU 2080ti
Internet 500Mbps up/down
While streaming GPU max load is under 40% and CPU under 15%. I'm using NVENC at 15k bitrate.

What am I doing wrong? Any help would be immensely appreciated.
 
Keyframe interval should be at 2 for streaming. Also, never stream above 10mbps, as YouTube won't allow it. For recording, it would be best to use CQP values of 18 or 14 or a high bitrate of 50000, but for streaming, set your bitrate to something like 6000, or 8000 if you're pushing the limits. Your computer is pretty decked out, so it should be fine to push these settings. Also, depending on your CPU, you might be able to stream at x264 medium, fast, or slow, if your 9900K can push it. Might give slightly higher quality.

Thank you for your reply.
I thought YouTube allowed for whatever bitrate as long as you can sustain it (and your viewers can).
I tried lowering the bitrate and i just lose quality (more grainy).
I gave it a shot with x264 but I don't see an improvement over NVENC, they quality is similar and the artifacts are still there during high action scenes. I tried different setups, at slow I start lagging frames.
Also recordings are perfect with the same settings, no blur at all.
I will try to see what happen if I stream on different service (maybe it's just YouTube not working for me). Anyway if you have any other suggestion I'm happy to try.
Thanks!
 
YouTube allows high bitrates but transcodes everything, so there is always quality reduction.

Some suggest upscaling to 1440p to trick YouTube into giving you a higher quality transcode.

You're still going to get artifacts under high motion on complex frames.
