Windows 10: Client Server Runtime Process using a lot of GPU power without a fullscreen program running?

So I noticed my pc lagged a bit sometime and i figured out that whenever I don't have a program on fullscreen on my first monitor my Client Server Runtime Process uses a lot of gpu power as seen in the first screenshot.

But whenever I have a program like google chrome or even file explorer on fullscreen it drops down to about 0% like in screenshot 2. I found this very weird and wanted to know if anybody got a fix. I already runned a antimalwarebytes scan and quarantined everything. also I checked the file location of this Client Server Runtime Process and that also seems to be the legitimate csrss.exe inside the sytem32 folder.



I hope anybody got an idea on how to fix this.

Client Server Runtime Process sucking 40-50% GPU...

Client Server Runtime Process sucking 40-50% GPU while watching media. It just bumps up causing frame drops in the video. I tried setting the priority of csrss.exe to low but that didn't help. Also changing the priority of dwm.exe didn't. Please help me
fix this, this is a nuisance. Thanks!

 

Client Server Runtime Process using 40-70% of GPU

I was trying to fix one problem I was having, and while trying to fix that, I ran into another. The other one can wait, because I cannot fix the other one with fixing this one first.

So a service called Client Server Runtime Process is taking up anywhere between 40-70% of my GPU while watching youtube videos or streams on Chrome. Goes down to 1-5% when not watching anything. Did as much digging as I could and this is what I have done
so far.

-Ran Malwarebytes, RogueKiller, Windows Defender, tdsskiller, AVG, superantispyware professional, bitdefender for checks of coin mining stuff, nothing came up
-Process goes back to C:\Windows\System32 , ending process requires checkbox losing data and shutting down comp
-Checked process details in process explorer, everything points to it still being the real deal
-Windows up to newest date, GPU drivers newest drivers, BIOS latest, everything is up to date.
-Registry cleaned, junk and trackers dumped
-Rolled back GPU drivers, and windows, problem still persists

Then I stopped all my extensions on Chrome, nothing changed, I do not have accelerated on either. Tried Edge, Edge just used straight GPU from the browser. So I downloaded Firefox, had no issues with GPU being used under 5%. I proceeded to uninstall Chrome,
[forgetting to save my bookmarks], re-install Chrome. Find that it's using GPU now from the browser, turn off acceleration, now it goes back to Client Server Runtime Process, and goes back to using 40-70% of GPU while watching youtube or streams. Everything
on the radeon settings is disabled, most useless things and none of them are running, nor have they ever been.

A Lot of the solutions were related to GeForce shadow play being uninstalled or something Nvidia related, which I cannot do and do not have as I run AMD. I can't think of anything else to do or have find any solution, I have seen some people have this
exact issue but they never are responded to leaving it unanswered. The only thing that I can say maybe related is, before this was happening, which was fine earlier in the day, was while trying to fix my previous problem, which required me to try and install
an run a game on a separate harddrive. [ Trying to figure out if my main harddrive was dying or not]. I can't even play the game when this system process is using 40-70% of my GPU. I then uninstalled from my other drive, restarted, problem still persists.
All games are from Steam, yes my Windows is legit. I spend my my time on the most used and popular sites, never click ads, I haven't downloaded anything random besides all these tools to trouble shoot. Any help?

Additional info, if I am watching a youtube video or a stream, and click lets say, on reddit tab while the video/stream is still playing and I can hear it, the gpu usage from Client Server Runtime Process goes back down to 0%. As long as I cannot see it,
it's fine, but if I can, it starts using GPU again. Regardless of how many youtube videos I can make appear on my screen, the usage doesn't go past 70%. Not really looking for reformat answers, as answers to this could help others. Plus, I could just use Firefox
and problem fixed, but rather try and figure this out as the issue could be bigger. Hopefully this doesn't get lost or un-responded to like some other forums, i'm trying as many as I can to figure this out.
