You do know the I5 2500k and the I7 3770K both have 4 cores?

Please watch and understand this

i know that. I'm not a noob you know. I know it's 8 threads but still 4 cores. Still think crossfire needs a beefy cpu.

What has my 460 got to do with it?

I run Bf4 on high @ 1080P with 45 FPS.

your 460 doesn't need a stongs cpu to power that's the thing


Intel 8 core consumer CPU's will be hitting the market in the 2nd half of this year, with a new chipset and will use DDR4 memory.

This video will explain how to use D3DOverrider https://www.youtube.com/watch?v=WhhXqgOsFbM

Basically it gives you a stable frame rate by enforcing triple buffering.


Lol the game is already using triple buffering. Just to be clear to anyone. I tried everything in the book.

1. Triple buffering
2. set renderaheadlimit in the game itself
3. unpark cores
4. winodws 8.1 and windows 7. (get more fps in windows 8.1)
5. timer resolution
6. performance mode in windows
7. reformat pc
8. latest beta and non beta drivers
9. stock and overclock cpu @ 4.7GHz

So as you can see I pretty much tried everything there is to. maybe there is something else but I don't think so. I'm not a noob as I work in IT and I read up a lot about what is the latest thing from intel etc etc. My overclock is stable cause if not them my system will blue screen or freeze.

So then why do I see 100% cpu usage. Clearly my cpu is the bottleneck. It could be a driver issue but how long do we have to wait for a working driver then. It's been 6 months now and I still have issues and just to say again, most probably you guys don't run my setup.

2560x1440 @ 120hz using crossfire etc etc I just think my cpu can't keep up with this resolution. why must everyone be so angry and keep on telling me no your cpu is fast enough. Can't you at least help me in fixing it. I won't be upgrading if my cpu load wasn't at full load 90-100% load most of the time. Please get your facts straight before attacking me here

Mantle works fine for me.

It works well for some but not others, I dont see how OP thinks a I5 2500k will bottleneck a R9280x

The whole point behind mantle is to take load OFF the CPU should you have a ****ty low end CPU.

And the 2500K isnt ****ty.

Any way, the proof is in the pudding, lets wait for the benchmark.

BTW the 2500k is not a bad cpu just not enough. and new games will make use of more cores so better performance and less frametimes.


First, just so we're on the same page, the i7-3770k has 4 cores and 8 threads because it has Hyperthreading, the i5-2500k you have has 4 cores and 4 threads, it has no Hyperthreading. Hyperthreading gives around 30% more speed than a CPU without it.

Now Hyperthreading fools the system into thinking the CPU has 8 cores when it only has 4. The general consensus is that Hyperthreading does not improve performance in games, only programs such as Autocad and programs that require loads of threads.

From the benchmarks I have seen Hyperthreading in Battlefield 4 actually decreases performance than not having it on in the first place, this could be due to the game being poorly optimized (not surprisingly).

Personally I think you have wasted your money on getting the i7-3770k for gaming, if you are going to use programs like Autocad ect then it was a good investment. I would of gone for a 8 core AMD CPU instead. If you gain performance then good for you, please post the results as I would be interested in seeing how it compares to your i5-2500K.


Show me the benchmarks. I want to see 2560x1440 and crossfire systems with AMD gpu's prefer my gpu's not the 290x and see if you get more performance oh and they must run windows 8.1 and battlefield 4. guess what they can't.

Again a fail review. They test GPU's with a fast cpu and then they do it crossfire and that's fine but not with a slow cpu then when they do the cpu tests they only do single card and there they fail again. So I think no one in the world get to understand me on this. i will even have one of you come to my house to come and look for yourself. I can also get low cpu usage by disabling one card or reducing resolution and say hey you don't need faster cpu...lol

Ive left out 1 very important question, how many FPS were you getting before you installed the mantle driver?

Almost the same. i can't remember exactly. but new drivers is optimized for newer games like thief etc etc so will use the latest drivers. Still had massive cpu spikes in BF4 and some other games to. not always but just in certain areas.

Hust to say again. how come people say my cpu is still fine for my setup when I get 100% cpu usage in areas. i bet someone go get my system pair with i5 and go on bf4 then play siege of shangai at c flag and run around there a bit to see cpu usage. I bet you will have high cpu usage where you start seeing lower than 99% GPU usage and also fps drops.

So you get 20FPS with dual R9 280x's with out mantel? Sounds like a crossfire bug.

Also whats your CPU temp when in bf4?

not 20fps without mantle but with mantle i get 10FPS. Without mantle it will dip to like 80FPS and make me stutter. hint cause of 120Hz monitor and no i'm not playing without sync. My games tear to much.

CPU temps max is like 60C. I already checked via CPU-z to see if my cpu is actually going to 4.7GHz. I also tried overclocking without using turbo boost to hard lock it to 4.7ghz same issue. like i said before when using mantle it works for a little bit but people say it's because mantle is starting to do memory swap so that's why i'm lagging then. so for mantle actually not entirely to do with cpu. I'm not upgrading to make mantle work right. i'm upgrading to make all my games work better on Directx.

What drivers are you using?

Uhm I said 14.3. i tried all drivers since since 13.12 and same issue

No, you did not. You said 'latest drivers', which doesn't tell us whether it is the latest beta or stable release, or whether you've just got it wrong about which drivers are the latest.

Does BF4 mantle have the same problem with only a single card?
Have you tried testing each card individually to see if it is the cause of the problem?

Here's from playing about 10 minutes with everything set to ultra and 4x MSAA 1920x1080, Mantle:
CPU.jpg

CPU average usage was around 40% maxing out at 59%, so once again if your CPU is hitting 100% something else is buggered

Have you tried running Mantle again after installing the 14.3 drivers, I see there was a specific issue with V-Sync and Crossfire in BF4 that was resolved
BattleField 4: V-sync issues observed on CrossFire configurations (with Mantle enabled) have been resolved

Quick breakdown of my machine:
Core i7-4771 CPU
Corsair H100i Cooler
Asus Z87-A MB
32GB Kingston Hyper-X 1600MHz (I run VMs that's the only reason I have more than 16GB)
Sapphire Tri-X R9 290 OC Edition
Intel 240GB SSD
Asus Xonar D2X Sound Card
Vantec Voltra 1050+ PSU

Planning on getting a second R9 290 in a couple of months time

Just thought about it now, do you use on-board sound or a dedicated sound card?

yet again you have 1x 290 and no crossfire and you run 1920x1080 and not 120Hz. you have i7 haswell and even you see almost 50-60% cpu usage so image my cpu.Mantle is only optimized for 290 and 260 gpu's. uhm yes I tried mantle again and same issue and even with a clean install of windows 8.1. They said resolved for r9-290 and r7-260 users but not my cards cause it's not fully supported yet....lol

I use Sound Blaster Z

No, I saw a peak of 59% which was most likely on the loading screen looking at the time it was logged and an average of 40%, it rarely went above 47%

My CPU isn't that much faster than yours and I'm willing to bet at the clock speeds you're running it will be very very close in performance.

120Hz isn't going increase the load on your system and adding a second card definitely won't double the load on the CPU

So found some 2500k vs 4770k benchmarks with and without crossfire:
http://www.dslreports.com/forum/r28517633-I5-2500K-vs-I7-4770K-Gaming-Benchmarks

At stock speeds, single card the average improvement was 2.75%

Stock speeds, crossfire the average improvement was 6%

The average improvement when OC'd to 4.4 with Crossfire was 8.75% and if you look at the 2500k OC benchmarks vs 4770k stock benchmarks you'll notice that the 2500k @ 4.4Ghz is faster than the 4770k in all but GRID 2 and Stalker.

Don't argue he's convinced it's a cpu bottleneck(it's not) and has already bought the new CPU...

OP where did you get it and how much btw cos I'm looking for one too?

PS: when this doesn't fix ur problem can I have it? ;)

I was thinking CPU thermal throttling, but that doesnt seems to be the case.

What about a unstable OC?

There's actually nothing wrong, he's playing BF4 at 80FPS on a 120hz monitor so I'm presuming it's that causing the stutter... It's a V-sync issue nothing more.
