6990 BF3 Dilemma.

post #1 of 38
Thread Starter 
Ok Im pretty much stumped right now. I need some serious insight on this.

I have 11.11c and CAP1 and I'm getting 85%-90% GPU usage in BF3, kinda pissing me off considering a single 5970 pegged 99% all the time.

I have my 980X overclocked to 4.2Ghz, but still for one card that should be more than enough, at least I think so?

I'm wondering if my 980X is really choking the game or vice versa because CPU usage is 99% on MP and GPU 85-90% usage and It's really bugging me considering I want to upgrade to 7990 in march.

I really don't want to upgrade my CPU until whatever is AFTER Ivy Bridge dies off. I'd figured the 980X could hold me until then, plus I don't feel like dropping the cash on a new mobo, ram, and cpu.

Here's something strange everything maxed including MSAA 4x I get close to 99% about the same FPS. But when I turn off MSAA I get 85-90% GPU usage same FPS. This is all at 1080 Ultra.

Again this is only in BF3 MP. SP and ever other game that supports CFX my GPU's peg 99% usage. I'm wondering if it's just BF3's MP unoptimized.

Please If im being bottlenecked, tell me I need to know and If am; would I really have an advantage and would it be worth the amount cash upgrading to Ivy Bridge once it comes out?.

I have a 2600k at 4.5ghz and trifire (6990+6970) at stock speeds. In the single player im seeing about 2 gpu's on about 99% useage and my 3rd around 90%. Im using 11.11a with cap 3 atm. Hopefully thats a bit insightful for ya smile.gif let me know if you want me to check my cpu useage/ mp gpu usage

Looks like a cpu bottleneck to me. I have had 99% usage on both gpu's since 11.10 cap 1. Even though your cpu is a beast, BF3 only uses 4 cores and it uses a lot of the cpu.

980x is the bottleneck? Something doesn't seem right about this.
post #5 of 38
Theres no way a 980X is bottlenecking a 6990. I realize BF3 isnt a highly CPU intense game, but 4.2 should be plenty for a 6990. Did you try driver sweeper to clean all ATI drivers from your machine, and install the newest drivers and CAPs? I believe there is a newer CAP out than what you are running.

Yes, I always do this thoroughly, Ive had the same result with all CAPs from 11.11, Strangely anything 11.10 and below including CAPs I get that horrid stuttering.

I ran into the same problem. What I did was this:

1. Uninstalled Catalyst Control Center and any CAPs
2. Use ATIman uninstaller in Administrator account (from what I read this isn't always necessary, but in my case it wouldn't run in my account despite being in the Admin group)
3. Rebooted in safe mode and ran CCleaner registry
4. Boot normally, download WHQL 11.11 release and CAP3

My performance on my crossfire 6990 literally went from 23-40fps to 80-130fps with no stuttering @ 2560x1600, all ultra, 4xMSAA, HBAO and my GPU usage dropped around 10-12%

Hope you have the same results....Seems to be hit or miss.

Just got HD 6990. It get 99% in MP @ 2560x1440. Same goes for 1680x1050. I am using CAP3. You might have to try different drivers.

With a 3930k? hmm....

Also I want to point out that as for Single Player, my results tie right in with Tom's Benchmark:
amd%20high%201920.png

But again in MP I have that horrid 85%-90% GPU dilemma. I find this very strange.

If anyone could run a test in MP with a similar if not more potent CPU and check their GPU usage and post results I would greatly appreciate +Rep.
Before I resort to drastic measures as KidKB had to do.


@ZealotKi11er, That's 11.11c + CAP 3?
