Hello there,

First off, apologies if this is the incorrect section to be posting this into.

So currently i'm using OBS Studio to stream to twitch (As most are i'd assume), however currently i'm noticing my steams may be a little blurry, and the quality somewhat poor.

Two example videos here and here, if used in theater mode looks very blurry. I'm very curious if there's settings I can adjust in order to up the quality, i'm going to list some of the settings i'm currently using below as well as hardware:

Hardware:

CPU: 6700k
GPU: GTX 1080
RAM: 16GB DDR4

Video

Base resolution: 2560x1440
Output resolution: 2560x1440
Downscale: Lanczos
Common FPS: 60

Output (Advanced) - Streaming

Encoder: NVENC H.264
Enforce streaming service encoder settings enabled
Scale output: 1280x720
Rate control: CBR
Bitrate 4500
[Rest is default]

If anyone has recommendations for me it'd be greatly appreciated, i'm fairly new to this and just do it for some fun, but I still want to maintain some quality to the videos if at all possible.

Notes:

I use the same machine to play as encoding
I use NVENC H.264 as the games I tend to play eat CPU fairly hard, and will cause insane dropped frames if done with CPU encoding, for example planetside 2.

NVEnc is good for recording but poor for streaming. It needs more bitrate to look good, which is fine when you're saving to a hard drive, but bad when you're limited to what Twitch accepts and what people can download. Use x264 instead. Since you're worried about it competing with Planetside 2 for CPU time, set it to SuperFast preset and post a new log using that from a 5 minute or longer stream of high action content.

That's a great response as well as useful, thank you.

I'll give this a test in the morning to see what the outcome is like, and link the resulting video as well.
