Hello I have been trying for so many hours in total its probably weeks now, to get a stream picture quality im satisfied with.
Ive been trying 1280x720, 1600x900 and 1920x1080. I have tried different bitrates between 5500-6500 kbit/s.
I have tried different framerates with those different bitrates at different resolutions, 35 fps, 48, 50, 60 and I dont know what to do anymore..

Only using NVENC, because X264 is just a little bit too much on my cpu for a 100% smooth stream.
I have tried to optimize my webcam without any good results. I am so tired because so many hours go into experimenting on a test Twitch account, when I really just wanna most of the time game and share what I am doing.

I have good enough specs for my PC.
i7 7700k oc to 4.8 ghz
MSI 1080Ti Sea Hawk X
G.Skill 32GB DDR4 3200 mhz RAM
All storage are SSD's.
Webcam Logitech C922 Pro Stream

My internet connection is 75/75 mb so its more than good enough and the pc and internet can deliver the smoothness without any struggle.

What I really want is just a nice looking stream without my face sometimes looking like a transparent chess board.
Ive been mostly doing 1280x720 at 50 fps with Low-Latency, High Quality at 6000 kbit/s, I really thought this looked ok, but crazy thing is ive seen others without twitch partner (they get better encoding benefits right?) getting a nice looking stream without that.

F.ex my friend Ullizzzz on twitch has incredible quality and even at 1080p60fps at 6 mb/s, but he dont wanna share his settings to me. Just look at how good this looks!!

Now if I go and set the same basics as him, 1080p, 60fps, 6 mb/s, I will get nothing but crap! or maybe it will look good at some times, but thats all!

Now I am seriously begging everyone in here.. please help. I need help, ive been using too much time on this it shouldnt be neccessary, I tried out what the youtube ppl recommend and in fact I probably know alot more by now than they do.

Here is my twitch testing account and you can see how many videoes that account the past 48 hours has, just trying different settings everytime but nothing works for me..

It looks like your room slowly gets brighter and slowly gets darker, mostly depends on how bright the game itself is. This can happen when the TV/Monitor is too bright and room is too dark. ... Especially when the game flashes white, it also flashes the whole room.

At 9m21s (9:21), the whole screen seem to slowly get brighter then darker, some kind of game effects? Whatever it is, it is also making the room get brighter or darker on the camera, probably from bright screen and dark room.

With constant bitrate as required for live stream, it is normal to look very good quality with little or no motion, and lose some quality with very high motion and high details, expecially grass. Best example on how bad the quality could get over super fast motion on green grass is Rocket League game. https://www.twitch.tv/directory/game/Rocket League

Yeah ive actually been suspecting this myself, My monitor is an ASUS ROG Swift PG279Q and its pretty bright but my room doesent have much lightning and the new Need for Speed Payback game has the effect when you use Nitrous then the screen brightness immediately goes bright so its not a good combination I guess.

What I need to get is a living room lamp, and a deskboard lamp.
As for quality I cant really do more than 6 mbps otherwise I am over Twitch limits, not bitrate would be a problem I see ppl do 6,5 and not getting banned, but I also dont wanna go to high in case somebody dont have the best internet.

Is there anything im missing out on when it comes to those extra options in output?
I always use Lanczos filter, Twitch users who use Bi-cubic have a little jaggy picture in my opinion.

If I would use Advanced Output Mode, however whats rly weird is I found the bitrate on simple being more constant in hitting the set target than on Advanced, dont know if its just me but this is why I have been using Simple Output mode.

And another weird thing is I feel 50 fps is better for a clearer picture, ofc 60 fps looks more smooth but 50 fps aint bad either, but is it that with less frames in the picture the bitrate has more "power" to those lesser frames, giving a better picture since it has "more" to give on those less frames? f.ex 30 vs 60. Im mostly a fan of either 35 or 50.

With only GPU based encoding there is not much to improve.
Lower resolution and loswer frame rate will give less blur in high detail + high motion scenes.
x264 and a preset like faster or even medium will squeeze a little more quality out of the bitrate, but that is CPU heavy so you would need more cores.

As far as I know, NVENC on Pascal cards has better Quality than QuickSync (and even better than x264 at crap settings like UltraFast).
x264 @ very fast is the best compromise between CPU load and encoding quality and provide better quality than NVENC.
x264 @ fast or medium preset will increase quality quality even further but the difference is not huge whereas the CPU load will be increases extremely.

Thanks all, I will use NVENC because its the smoothest and can handle load but also quality not too bad.
I will also do 720p as I think the 6000 kbit/s has more to give to this resolution.
I think 1600x900 might be just a bit too much.

I play a lot of Rocket League and on 720p can actually make it look better than 9/10 ive seen, except when theres goal cuz the motion and detail and lightning and everything, it will kill my webcam quality on picture but it will go away also.
