Question / Help Best OBS setting for streaming?

[JustSamael]

Hello! I have a little issue to solve. I've been streaming for 1 month but i've noticed that my stream quality is good but not as much as i'd like to. I've tried to use my CPU for streaming, but i have i5-4690 and stream used to lag a lot, so i decided to use my GPU for streaming , i have an AMD R9 290 Tri-x Sapphire 4 GB.

Here's my pc spec :

→ CPU : I5-4690
→ GPU : AMD R9 290 Tri-x Sapphire 4GB
→Memory : Kingston HyperX 16 GB DDR3
→ MotherBoard : Asrock fatal1ty h97 Performance

When i decided to start streaming with my GPU, stream was perfectly fine, no lag at all but i noticed a lack of quality while my character was moving, like in these pictures down below here as you can see :

When i stand still and i don't move at all :

- When i start moving :

I give you my OBS Settings down below here, i'd like to know if there's something i can change in my OBS settings in order to remove that annoying pixelled effect or if i have to buy a new CPU, i was planning on buying and i7 4790, hopefully with that i can fix my issues. Settings :

1 )

2)

3)

Currently my stream quality is 720 60fps which is the max quality you can have on twitch, no lag at all only that annoying pixelled effect. What do i do ? Thanks

Your bitrate is quite low, combined with the poor quality of the AMD encoder this will cause artifacts during high motion.

So there's nothing i can do ?

Increase your bitrate to at least 6000 kbps. Lowering the resolution or FPS would help too.

I've tried to put 5000 bitrate and 30 fps but after a bit stream started lagging , quality was better tho
