Hello guys, I am using i5-4670K, a while ago, I was playing for first time BF1 and the CPU was 100% lag, low fps etc, and I knew that I was on minimum specs. Beta was working just fine. 1 week later, I installed BF4, and from that day I got some spike lags while playing multiplayer(medium settings, 50-60fps), and the last few days I am playing the Campagain, and the cpu is 100%(and cpu is making sound). My pc was cleaned from dust so it's not that the problem. Also, drivers are on date, and anti malware didnt find any virus. The fact is, 1.5 month ago, my pc got virus but I cleaned it, but I am suspicious, that there is still something wrong. Should I try to format my PC? or is something else the problem? Also, I got BF4 about 3-4 years, and the CPU 2-3 years. Thanks for your time!
I am on Win10 64bit.

Sounds good, I'm glad it's sorted for you.

If your not certain any viruses have been fully removed it may be better to reinstall the operating system. What antivirus do you have? For malware did you use Malware Bytes anti malware?

Is it constantly at 100%? It sounds unusual for 60 fps and K series processor. Is the CPU overclocked? What is the rest of your system, GPU, memory, monitor resolution etc?

I am using Microsoft Security Essentials. I have used, Malwarebytes(pro version).
97-100%. No CPU is not overclocked.
My others specs are:

GPU: MSI GTX 960 Gaming 2GB
Ram: 8GB(But I got only 1 slot. And I am thinking that memory is the problem, not sure!)
Monitor resolution, 1980x1020, windowed mode.

I had never any problem before with same specs(or even worse, 2 years ago I had GTX 650 1gb. and it was smooth.)
I am considering of reinstalling the OS.

Is that a single 8 GB ram stick? If so that is likely your problem. Single channel ram is know to cause performance issues with BF1. Yes it is normal to see the i5 hit 90-100% a lot in BF1 but you should not be sitting there constantly, you should average around 80%... You'll want to find the maximum graphics settings the card can run without dropping below 60 fps. What speed is the cpu running at? You may also benefit from an overclock. Since you have that feature you might as well take advantage of it...

Yes its single. My main problem is not BF1, I just set an example. I know that my cpu is bottleneck on BF1.
But in general my CPU is 100% while playing games, a problem that I didn't have in the past.
My cpu is 3,74Ghz, but I don't have cooling for keeping temperature low.
I may reinstall os to see if the problem will be solved, thanks for your replies!

I'm not 100% certain but I think single channel ram may cause performance issues for gaming in general, I think a single ram configuration has less bandwidth than dual channel for example.

How recently has the CPU been hanging on 100% and what did it do before this started happening? What CPU temperatures are you getting? What cooler do you have?

I may search for my old RAMs to do some tests.
Don't know exactly, because while I was playing I noticed some performance issuses, so the last few days I saw that BF4 was struggling some times. The CPU temperatures are normall, same as for GPU. I don't have one. I am using their fans only. I have format the OS, and I am going to see what things will go. Thanks for your time!

Let us know how it goes with the OS reinstall, it might fix something. Exactly what CPU temperatures do you get just in case that is an issue.

I just reinstalled OS, it seems fine right now, played HITMAN and the cpu is around 65-75%(normal). I am gonna run BF4 in a few days to see! But right now, it seems fine.


I am going to look about that.

I think I found out, what was the problem. From the BIOS Intel GPU was enabled. I was curious, because my GPU fans wouldn't work until the C was very high. After I disabled that option on BIOS, usage on HITMAN game was around 55-75%. Thanks everyone for your time and help!

Intel GPU? Is that exactly what it is called? What motherboard do you have? I'm surprised that was enabled if it's what I think it is.

What graphics card do you have? With MSI Afterburner you can create a custom fan curve for it and run it so much cooler. I've seen so many vids from people with their GPU temps over 70C, it's like they don't know how to set a fan curve...

Intel® HD Graphics 4600. Gigabyte Z87M-HD3. I am using MSI GTX 960 2GB Gaming. Yes I am going to do some changes with fans. By the way, until now, I got normal cpu usage!

I've had a look at your motherboard's manual, are you sure the on-board gpu option your referring to in the bios isn't called Internal Graphics? Default is [Auto] Is that what it was on?

I note you reinstalled the OS? Did the Cpu usage reduce after the reinstall or after disabling the on-board Intel graphics?

Yes that's it.

The CPU usage was reduced while gaming.

I recommend trying to disable onboard CPU first, and If they don't see any difference, they should try to reinstall the OS.
