40% Xfire GPU usage bf3

[NoobCannon]

Run BF3 with a single card, report back the GPU usage and frame rates.

ive only just installed the second 7970 but before I was getting 99% usage

will try again with one card once bf3 is reinstalled

any help is appreciated tbh, ive just tried again dropping my clocks incase it was an instability problem but the usage stayed the same.

and also as I said earlier pretty choppy!

Well ive found a cpu bottleneck or gpu usage issue is the main cause of microstutter, so we have a problem there. However if you want you can try using this config file i created for a friend. Place it inside your main battlefield 3 folder and see if it improves your gaming experience. I'm afraid it won't help your low gpu usage, but it might improve the overall experience.

Let me know how this works for you, i can tweak it further if needed.

I don't think anyone's asked but what drivers are you using?

What tool do you use to test GPU ussage?

EDIT: sorry got it GPU-z

im using cat 13.4's [latest whql driver] downloaded from amd's site today

What tool do you use to test GPU ussage?

afterburners OSD, I know its working as It reports 99% in haven etc and I got a reasonably good score!

You can use either msi afterburner or radeon pro to enable an on screen display to monitor gpu usage, fps and other goodies. It really is a nerds wet dream.

I only get 50-60% on each on my cards but i am pretty sure it's my cpu bottlenenecking it as it should be a lot better with a 4770k soon.

Are you using vsync or any form of fps limiter?

 

[Sycho]

Not using vsync at all, i get like 70-80fps most of the time on Caspian Border 64 player server with ultra and 4xmsaa at 1920x1080.

 

[Ian Evey]

Definately not cpu bottleneck, are the fps definately going over 120fps in bf3 ? It might have capped fps in bf3 itself ( settings or config ) or by your driver software ( ccc or whatever ).

^ all just thoughts, but it is not your cpu causing it.

Another thought , run single player for a few mins to see if that does it?

If i get a chance Sycho, ill try my 670's in my other rig, (i7 930). If i can get it running at 4ghz, be interesting to see the card use in it and compare to the 3770k.

What settings are you running at? If you're running low settings the CPU bottleneck increases.

Blimey i get higher than that on 1440p with 7950 crossfire. Maybe that cpu is holding you back, surprising though given the fact its an i7 and you have it clocked at 4ghz.

What speed did yours run at setter?

4.2ghz on my old 920, the only multi gpu setup i ran on it was a pair of gtx 470's. I do have a 930 based second system as well though.

Sounds like you've been stock piling those i7's incase of another potato famine.

Ok i got sli recently so i have no idea what drivers are best for it for what games but i've tried so far:

BF3=scaling seems there but on open maps it's poor, only see it 100-120fps on close quarter maps really.(has gone over without vsync, highest i seen is 165 but that was low settings, was testing )
Hitman=Some scaling about 30fps more or so.
Borderlands 2=40% or so useage on each card, about same performance as 1.
Starcraft 2=Abyssmal, worse performance than single card, was getting 50-70fps.
Metro Last light=Worked good, 70-100fps maxed.
Crysis 3=seems to work good, about 70-90fps most areas unless lots of stuff happening.
Witcher 2=Good, usually about 100fps maxed.

I've used 314.22s now using 320.18s which hasn't caused any issues just poor sli scaling in some games.

Please do that Setter would help a lot.

Tbh im more worried if theres gonna be a guinness famine. One i7 for a keg o stout and a tank of gas.

Will see if i can get them running in it over the next few days, driver wise im currently on 320.00. Ive checked fps in bf3 with the ab osd running. Seeing upto 150 fps with the settings at ultra with x4 msaa, 85 fov @1920x1200, 91% usage per card.

 

[Sycho]

What map was that on?64 players too? i play with 90 fov aswell which lowers fps a bit too but was expecting about 100fps or so on Caspian.Did you have much issues with the games i listed?

 

[setter]

Map was a 64 player metro server iirc. Dont have any of the other games though. Ill try a quick blast on a 64 player server on one of the larger outdoor type maps.

 

[LtMatt]

Test Caspian, Firestorm, Baandar or one of the other large vehicle maps is probably best. Metro is not that demanding on the cpu.
