Hello everyone,

I want to ask you about settings of OBS because I have bought new GPU about few days ago and after switching my stream is blurry with absolutely same settings like before but before Ive got no problems.

My uploud is 20mb/s
OLD GPU: nvidia 960 GTX 2gb memory
NEW GPU: nvidia 1080 GTX 8gb memory
CPU:intel i5 4690k running around 4,5gHz
drivers was reinstalled right but I didnt reinstall whole system maybe it can cause a problems but I dont thinks so.

Im encoding with NVENC bitrate 5000 resolution 1920x1080,30FPS. I cant stream throught CPU bcs it cause stream lags :(

I really cant find solution why is my screen blurry like a hell with much stronger GPU when it was everything ok before.

Thanks for every help.

www.twitch.tv/wheaze last video is with new GPU you can see small pixels and with 60 fps its unwatchable :)

The most recent video at the time of this reply, have a different resolution (1080p) from a few days before (864p).

Did you change in-game settings?
Increasing in-game quality like texture resolution and more grass details can worsen video compression. Extra details still have to compress to the same, constant bitrate, losing quality of live stream anyway.

Hey @wheaze https://www.twitch.tv/videos/213328347 is hardly unwatchable.

Honestly looks better than 80% of most PUBG streams I've seen.

The only thing I noticed is that your stream source didn't specifically say 1080p60 like I've seen on a few other streams. I'm not sure if this is a twitch transcode v2 thing or if maybe you need to double check that your FPS is set correctly in OBS. If I'm reading your log right, I think your keyframe interval is set to 120 as well, which I've seen everyone say it should be set to "2" in all my streaming research.

Great looking stream though man!

If you want to do high quality 1080 via x264, you need a better CPU.

Your i5 4690 is a 4th Generation Intel CPU and outdated (today's production is in its 8th Generation). It has 4 cores, but only 4 threads, and thus does not support Hyperthreading which is very beneficial in parallel environments, like doing x264 encoding.

If you want Intel 8th generation, go with the new i7-8700 (6 cores, 12 threads).

Thanks man but i can still see some pixels which wasnt there with old gpu and in setting Ive got set keyframe to 2 so idk why its in log as 120 :O I will try to stream in 720p maybe it will be even better :)

I know I cant stream throught cpu thats why im using Nvenc :) atm I havent money for new CPU :(

I have increased a quality of game from low to medium but even increased bitrate so thats probably not what causes blurry screen :( and stream is blurry still no matter what game i play :( I want to stream in 1080p60fps but I think 6k bitrate is not enough for Nvenc. Thanks for every idea how I can fix it

You're streaming to twitch, and twitch's bitrate limits prevent 1080p30 and 1080p60 from looking good.
