[SOLVED] High CPU usage while streaming

[turret001]

I suck at introductions but, hi everyone!
My games started stuttering after buying a new monitor and I don't know what to do.

I have recently bought a 144hz screen and I'm running a 3 screen configuration. All on 1920x1080, 2 of the screens are on 60 hz and the main one I use is on 144 hz. I have noticed that after plugging in the new monitor, my games started stuttering and there were CPU related 'drops' on OBS. Here's a benchmark I did:

https://www.userbenchmark.com/UserRun/25952207

I've monitored my CPU for temperature issues but it was not going over 70C.
I don't know what to do. I've already ordered an rtx 2080 and I'm worried that plugging it in will make everything worse.

Sorry if I made any grammatical mistakes, I'm not a native English speakers.

post your complete system specs here.

no way to know why your system can't handle the output without knowing what it is composed of. but pushing 5760x1080 is not easy for any system.

if you are using 3x displays for gaming, they cannot run at different refresh rates simultaneously.

if only using the new 144Hz for gaming, it may just be that your CPU and/or current GPU can't handle the load and is constantly jumping back and forth from higher to lower frame rates. try locking the fps at different rates and see if the stutter continues through them all.

Known frame buffer desync issue arises from doing multi-monitor setups with different native refresh rates - resolution doesn't matter.
Try capping your 144hz to 60 and see if it helps.

Thank you both for your replies!

Hi! I changed refresh rate from 144 to 60hz using Nvidia control center but its still the same.

Idle CPU percentage is 14%.

If possible, can you guys suggest an upgrade? Thanks!

Upgrade what, exactly?
Are you just playing on the 144hz, or across all 3?

a CPU upgrade -if I should upgrade-.

no, all of the monitors are on 60hz right now. I switched 144hz screen to 60hz mode and I still get high CPU usage. I only play on one screen and open OBS & Discord on other screens.

Ignore that warning about B450 chipsets. Partpicker isn't up to date with the Msi MAX boards - they support Ryzen 3000 out of the box.

Thank you! I will check them out.

I'm only asking this because i'm illiterate in such matters; are there any downsides to using AMD instead of Intel?
Would an i9 9900k perform different?

I'm not trying to start a quarrel, I'm just asking because I never used AMD and I just want to learn more.

Yeah.
It's more dependent on fast memory and lower memory timings to get the most out of it - like 3200-3733mhz for simple plug-n-play.

This one's not really a downside, but it has caught MANY Ryzen 3000 adopters by surprise: these chips are very 'bursty' with lower loads.
This behavior is normal, but it leads them to have higher power consumption and temps at idle compared to the Intel you're used to.
At the same time though, it yields lower power consumption and temps VS the Intel competitor.

Would an i9 9900k perform different?

Pretty similar, but it's hella expensive for what you get. If you already heard rumors of the cpu being hot... they're true.

oh wow, you are right, these prices are incomparable.

I will definitely get an AMD Ryzen 7 3700x CPU then. I hope my DDR4 2400Mhz rams will be enough. Thank you so much!

Just don't upgrade just to fix this problem because this has nothing to do with the CPU.
The only reason to start stuttering would be the increased CPU usage that would be caused by going from 60 to 144Mhz and cutting FPS to 60FPS would stop the increased usage so the CPU is out as the source of the problem.

no, all of the monitors are on 60hz right now. I switched 144hz screen to 60hz mode and I still get high CPU usage. I only play on one screen and open OBS & Discord on other screens.

i would try disconnecting the 2 other displays, setting the refresh rate to native 144Hz in Windows > Display settings and Nvidia Control Panel, and check the monitor's own OSD menu to make sure all settings are also optimized there.
see if the stutter/FPS fluctuation stops.
