high cpu usage in most games

post #1 of 22
Thread Starter 
Hi there people

I have this issue and i'm making a new thread cause I hate to explain myself all the time.

My issue is that I have high cpu load in some games like BF4, latest Tomb Raider, crysis 3, etc etc. I'm running windows 8.1

My resolution is 2560x1440@120Hz. I only get 90-99 usage is some areas and my gpu usage is not going 99% but my fps drops. cpu is running @ 4.7GHz and running prime95 stable for 12hr

So here is the things i tried so far

1. Timer resolution
2. Unpark cores
3. Clean install of windows 8.1 and installing the latest beta drivers (all previous drivers same issue)
4. tried all drivers from 13.12
5. Check dpc latency and everything looks fine. used the latest latencymon.
6. running cpu on stock 4.5GHz and 4.7GHz and 4.7GHz seems to be the best.
7. CPU is not even reaching 60C in games so no overheating issues. I also checked if cpu is running full speed on all cores when gaming and I even overclocked my cpu without using turbo mode so all cores should run 4.7GHz all the time.
8. in BF4 Closing browser when I joined a server.
9. Tried mantle and it lags after about 10min or so. my fps drops to 10FPS in won't go higher.
10. changing renderaheadlimits in BF4 and still same issue.
11. Frame pacing on and off same issue

So I bought myself a second hand 3770k from someone just waiting for him to ship it to me and then I will see again. But now I just want to know in the meantime what i can check to see if something is bottlenecking my system or if something might be wrong with my pc. I'm starting to think amd was not such a good choice and should've spend more money and went either 1x GTX780 or even sli cause looks like AMD need more cpu power to actually crossfire.

So what else can I check in my pc to see if maybe there is something else faulty on it and sorry if this is in the wrong section.

Thanks

I think getting the 3770k should do the trick. Heres what i get with the same chip and 290 (xfire disabled). In my case, the cpu was the bottleneck (i had 2500k earlier).

So you also had this issue and upgraded cpu and you got better performance?

What did you upgrade from

2500k. You can see the cpu usage hits around 30-40% (3770k) instead of 80-90% (2500k).

Cool so you say the chance is good that this will solve my issue. I think it's because of the more threads and faster per core speed and also the upgrade from pci-e 2.0 to pci-e 3.0. i think this will help in crossfire. So again thanks for the info. finally someone that understands my issue and actually giving meproof.

Crysis 3 is extraordinarily CPU intense. I don't know about BF4, but BF3 was heavily CPU bound in large matches too.

Tomb Raider is causing me some confusion. In my case a CPU bottleneck isn't obvious, but something's bottlenecking it and it's definitely not my GPU, so I think the software might just be misreading my CPU usage.

i have this feeling that AMD cards uses more cpu power cause the Nvidia cards offloads some off the load to the cards and thus allows for less cpu usage and smoother frames etc etc. my friend was playing Far Cry 3 the other day and he's only on 60hz panel and the game looked super smooth on his pc but on mine I'm getting microstutter etc etc. He's on ivy bridge i5 3570 non k and 1x GTX 760. i know it's not as high end but yeah can't wait to get my 3770k. going to try and overclock to at least 4.4GHz. but will first check how it's running stock. if stock clocks is still enough to make it stutter much less for me I will stick to that until i need to overclock it.

If you want to avoid microstutter, then using crossfire isn't the right way to go about it. Microstutter was one of the reasons I completely gave up on mult-GPU solutions.

Also, bear in mind that Far Cry 3 has known stutter issues. I don't have them on my Haswell/780 Ti system (although I have a bunch of graphical bugs instead), but many people complain about stutter. It sounds a bit like BFBC2 to me - BFBC2 had stutter issues on certain hardware that no-one could fix. It was just up to luck whether the game 'liked' your PC. That's what I'm reminded of reading about the FC3 stutter issues.

sometimes it's not microstutter i'm worried about but rather low fps and gpu's then not having usage of 99% and cpu usage is high then. That's my problem so maybe the 3770k will help me.

The 3770k is a relatively minor upgrade over the 2500k.

You've got a pretty powerful GPU solution, so unless you live in fantasy land with Brutuz, you're going to end up seeing CPU bottlnecks, especially at high refresh rates. The 3 reasons I ditched my GTX 780 SLI setup were microstutter, SLI compatibility issues/bugs and the fact that the second GPU was practically useless because games were mostly CPU bottlenecked. You can always put the unused GPU potential to work with supersampling antialiasing.
