Question How to fix CPU bottleneck on my new PC ?

[darceyo]

Hello. I have the CPU bottleneck in the most games on my totally new PC build.
I have RTX 4060 and i5-14500 and I can't believe it's bottlenecking.. but it is.

Any suggestions how to fix that?
I've tried to set the FPS limit and make the resolution higher than on my monitor but it's not always helping me...

How to fix CPU bottleneck on my new PC?
Simple answer; if your CPU is your limiter, you go for a CPU or a platform upgrade.

We're going to need more information. When posting a thread of troubleshooting nature, it's customary to include your full system's specs. Please list the specs to your build like so:
CPU:
CPU cooler:
Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
Chassis:
OS:
Monitor:
include the age of the PSU apart from it's make and model. BIOS version for your motherboard at this moment of time.

What titles are you taxing the system with and where did you source the installations for the game?

There is no reason that CPU should be bottlenecking that GPU, unless you are playing games that are very CPU heavy, or very poorly threaded.

How do you know this?

Unless the OP has a single DIMM, which is limiting the RAM bandwidth. That could cause poor CPU performance.

When I was GPU bottlenecked, the FPS limit helped me, but when I had CPU bottleneck I can't do nothing.. I mean even at 60 FPS it can push the micro stutter to me and the higher resolution will not help me (I'm playing at FHD on 240hz monitor, but I'm limiting the FPS in all games to 120, however it's not the fix for sure.)

Is it properly installed to work in dual channel ?

Is it properly installed to work in dual channel ?

Yes.
Slot #2 and #4.
Also, in BIOS it says that it work in dual channel.

Is your CPU overheating?

Is your CPU overheating?

No. The temperatures are pretty fine.
Never seen more than 65°C

I think you need to explain in a bit more detail how you're being bottle-necked before anyone can help you

Basically i'm playing the game, and it can load the specific CPU cores up to 80-90% (Not general CPU load but exactly cores/threads). And after some time I see the micro stuttering.

I have a feel like the game is not using all power of my CPU, however all power saving features like C-cores support and others are disabled in BIOS.

Hyperthreading is disabled too.

Slight lag is normal

Which CPU can fix that? 14700k or 14900k?

 

[MEMOFLEX]

What games are you playing that experience this stutter? There are some horrendously poorly optimised games out there so understanding which games will help

No CPU can fix all slight lag, including both 14900k and 7950x3d. It's the game to blame.

Here's the list:

Also, Hearts of Iron 4 is just lagging at 30 fps, seems that CPU can't handle this game with only 1 core which this game mostly use...

Can you provide your full system specs for reference to know what else we are dealing with. There are a number of unknown variables from PSU, motherboard model and VRM quality to SSD available space and monitor resolution.

Get all this info over and we have a fighting chance of getting to the bottom of the problem
