FPS drop due to CPU?

[gran172]

Hey, so while playing BF4 my GPU always stays at around 60-75% usage, the thing is when my CPU reaches 80% my framerate drops really hard, why is this? I mean, why can't it just go above 80% usage? My cpu is a I5-4590, temp is usually 65° when it gets to such high usage.

Sounds like a driver or OS issue. That CPU nor those temps would explain your problem. What is your GPU card model?

Sapphire R9 380 4GB (1050mhz core, 1450mhz memory), i doubt it's the GPU, i tried dropping everything to minimum and it still drops, GPU is never even close to 80% usage

I doesn't have to be the card itself, to have GPU and gaming related driver issues. The GPU card driver generally dictates much of the usage scenarios for other hardware when gaming. Chipset drivers could be relevant as well.

What are your full system specs including motherboard, PSU and memory?

CPU: Intel I5 4590
MOBO: ASUS B85M-G R.20
RAM: 8GB (4x1) 1600mhz
HDD: 1TB Western Digital Blue
PSU: EVGA 430W (i know, kinda short, i did some testing with it and never had a problem, 35a on 12v seems enough)

I just launched Witcher 3 which is really CPU heavy and it reached 85%-90% usage so not sure what it could be, seems there is something with BF4 that wont let my CPU use more than 80%

I'm guessing you meant 4GB x2 on the memory, not 4x1, right?

PSU is definitely underpowered, and is absolutely not high enough quality to be used at that level of underpowered. If that was a Super Flower or Seasonic 430w unit, maybe, but even then I'd be skeptical. Still, it's PROBABLY not relevant to your current issue, although I've seen power supply issues cause just about every possible glitch you could imagine.

Do you have the most recent BIOS installed for your motherboard? What are your BIOS, GPU card driver and chipset driver versions?

 

[gran172]

GPU driver is the latest one (16.6.2, haven't installed 16.7.1 because that's only a fix for RX480 users), MOBO i'm on the 2103 version and the latest one is 2201, haven't installed it because it doesn't seem to do much and BF4 is the only game where i'm getting this

Not sure what you mean by "doesn't seem to do much", but BIOS updates should always be installed unless they are brand new beta versions. Older beta versions that have not been superseded and have been available for a long period of time should be considered stable releases that just never got upgraded to full versions due to neglect by the OEM. For any BIOS release there may be other changes to the firmware aside from the primary, short description, offered next to the update description and in some cases can be important factors.

I can't fully express how many times I've seen unexplainable CPU related issues, and all kinds of issues really, that simply disappeared after updating the bios. Clearly that's not EVERY case, and it might not be related to your problem at all, but I'd certainly want to be on the latest firmware to eliminate it as even remotely being a potential contributor to your issue. AND, since the latest bios indicates it's primarily addressed factor is "system stability", you can almost guarantee that it's CPU related.

As to the graphics card, if you've ever installed more than one version of the driver, ESPECIALLY on AMD cards, you seriously need to run the DDU and do a clean driver installation. In fact, on my own machines, and on client machines, and in recommendations, I always recommend running the DDU EVERY time you install a newer driver. Takes five minutes and solves a plethora of issues that seem to have no root cause or ARE clearly driver related.

I'd also make certain you have the latest chipset driver installed, which for your system would be this one:

Thanks a lot ! Is there any tutorial that i should watch to learn to update the BIOS? I've never done it and it's kind of scary to mess something up tbh haha
