BF4 Retail CPU scaling measured

My gpu usage in bf3 is a good bit higher, but then im not hitting near the same highs in fps in bf4 as i was in 3.

Just the way it is with Battlefield. I don't think I have seen anyone who gets 100% on both cards in an sli/xfire configuration on a full 64 player map in BF4 ( or 3 for that matter).

Single player both GPU's run at 95%+ utilisation.

There seems to be some truth to this. I run a cruddy crossfire setup of 2x 7770's and although all the cores max out 100% at some point or other the average for them is 70-80%.

My GPU's seem to average 90% now often going higher, I am not running everything at max.
 
Have you tried it online Andy? In mp the usage does drop a lot depending on whats going on in the game. That and of course after you get killed you have to wait on the re-deploy screen.
 
Yeh, in single player both my cards are pegged at 95%+ usage. Multiplayer it fluctuates between 75-95%, 99% of the time.
 
Ive yet to even load up single player tbh. In bf3 i played it for about 10 minutes just to learn the controls etc. Should have my cpu oc'd again tomorrow so ill run a few rounds and monitor stuff with HWInfo. Found it to be best for garnering cpu/gpu info over the course of a round.
 
I still think that with vsyn off in ultra, your gpu's should max out simply because they are trying to render as many frames as possible. The proviso is that there isnt a cpu bottleneck, vsyn is off or your havn't hit the 200fps frame limit in BF4.

Like I've said I easily hit 100% gpu usage virtually all the time which is good because, it essentially means my cards are both trying there damn hardest to render the frames.

High usage has its draw backs. It can actually affect the overclock because after an hour or so the heat coming out of the case is very hot so I turn it down to 1150Mhz after and hour or so. (I'm gonna get a bigger case with 200mm extraction fans as I plan on getting a third card plus i7.)

I ask a few players last night who run sli and quite a few said the same as you Jono i.e. 90% usage so it may be card specific who knows.

I don't see how that is possible ( unless you are using insane amounts of super sampling), especially with vsync on!

If they are not overclocked cards and he runs relatively high resolution i.e. 1440+,1600, 5760x1080 then hes gonna maxout even with vsyn on.

We need more detail on hows its used really!!!

Like previously mentioned running a battlescreen tactical map effects my fps -10fps and also the cards are producing extra pixels for the second monitor too. It all takes up cpu and gpu resource which in BF4 is hit extremely hard even using a singe monitor at my res and settings.

Run a single 1080p monitor, via Radeon Pro V-sync is set to always on, frame limited to 59fps.

Full ultra settins and 4xmsaa, no super sampling applied.


Game was pegged at 95%+ usage during single player, and peaks at 97% in multiplayer.

Will take screens laters.

Well I'm shocked that 2x7970's hit 95% at those setting, because for me, with vsyn on (BF4 vsyn btw) I get 47-49% usage for crossfire.

Use BF4 vsyn, turn off Radeon Pro Vsyn, turn off frame pacing.

Also check that your not using vsyn twice. (Set in game and via Radeon pro)

You should be only using approximately half your gpu resource 50-55%.:confused:
 
Will check later, but 100% sure v sync is not enable in game or via the CCC. Both cards are currently at stock clock speed due to temps (untill new case and fan controller comes tomorrow) but memory at 1500mhz.
 
Just bought a 3930k last night, good to see games really making use of extra cores and threads. Damn good deal for the jump to X79 too
 
Should I upgrade my i5 750 at 4.1ghz?
I've been on the fence about it for a while but always decided to stick with my 750 a bit longer as it runs games fine. But now games like bf4 are out and starting to utilise the cpu more I'm starting to think I'd see a sizeable performance increase.
Would be looking at either a 4670k or 4770k.

yes you should

i saw a massive difference going from i5 750 (oc'ed to 3.9ghz) to my current i7 3770k
 
BF4 is not running smooth at all with my system! I have the graphics maxed out at 1080p and left the resolution scale (supersampling?) at 100%. This game stutters and jerks quite a bit :(.

Specs:

i7 3770k (stock 3.5GHz with 3.9GHz turbo on all cores)
3GB R9 280X Gigabyte Windforce OC graphics card (factory oc'd to 1100MHz)
8GB Corsair Vengeance DDR3 1600 RAM (2x4GB)
Windows 7 x64

Surely my PC should be able to run this game relatively smoothly maxed out at 1080p? All the latest drivers are installed too.

Supersampling means you are actually running it at a very high resolution and scaling it down to 1080p. Turning that off alone will probably fix your problems.

That said, your 280x could use a bit of further OC if you want some extra FPS; though it's probably not noticeable in real world use anyway.

You can also OC the CPU, but I am sure that is not the problem.

The resolution scale (i think it's supersampling) is set to 100% which is the default setting for 1080p according to the game. I don't really want to OC my R9 280X as it already squeals like a pig and it should be more than enough to run this game smoothly... It seems quite a few people are having this issue after doing a bit of googling.
