hi there.
i've a problem
when I stream some games (even if the problem is there even when I record) the camera becomes pixelated.
to give you an idea of the problem I will link you to my stream of a few days ago: VIDEO
in that live I use Win 10 Pro, Nvenc encoded (nvidia GTX 1050 2GB) with a Logitech C615 camera.
What can this problem depend on?

its not only your cam its the hole image with this "pixelation"
but your cam have x10 more details in the same area so you see it there more then on the rest
increase bitrate or try to work with settings

yes, I hadn't noticed.
the problem is general.
but it only happens with some games, not all of them.
what do you think it depends on?

It looks like you don't have good lighting and auto focus is having problems.

Go buy an inexpensive photography umbrella kit. Set it up to point at you. Also, use dark drapes to cover up any light entering into the room to make the lighting level always consistently the same regardless of time of day.

light have not realy something todo with "this" pixelation
its a regular bottleneck
you have a Massive Area of the Picture in Fast Movement
thats result in a Downgrade of the Quality and the codec looks what he can do to maximize the visual
most of your image have "low" details so it optimized to use encode settings by it save more quallity overall to ignore the 5% detail area
to optimize the most of the picture quality

"why doesn't it happen with other games? " you need not to look that from part of "game" you need to look how mutch % of your screen change every frame how mutch different colors visible .... all that need bits so a only black&white area 500x500 pixel with high change rate need less bits then a rainbow with 500x500 pixel the rainbow go pixel on slow movement and the black&white on fast movement

Edit: See this VIDEO <-- in that video only 20% of the picture changes in the pixelation video 70-80%

thank you so much for the detailed explanation.
what do you think I could do to remedy the problem?
I often see other streamers making videos with similar games but with far better results.
Could it be a limitation of my hardware?

Yes and No
First idk your settings you have not posted a Log with record details
The "Ultra HiQuality" are dual Setups with CPU encode in x264 with Massive CPU Monsters
and many Reduce the Pixel Like little more then 720p but not 1080
and other use more bitrate then the like twich 6mbit

the 1050 nvenc is not so good like the 1660/2060/2080 there are new generation there have "similary" Nearly x264 medium Presets with small more need of bitrate then x264
the 1050 is more like fast presets

I can post the log tonight from home.
in the meantime I should start thinking about changing my video card.
it's right?

its one option idk your hardware if you have a secondary "good" computer that can used for encode can be a option
or if your cpu in your game pc a monster and your games "Not need load" you can try that too
another option is to change to a newer better version of the nvenc chip like to buy a minimal 1660 (1660 2060/2070/2080 all same chip) (1650 have not the new chip its the old from your 1050)

its a good increase vom old nvenc to the new but idk if its the money a good secondary pc with ndni
