mediocre SLI performance

bummerman

It was just recently that I started taking advantage of the on screen in game monitoring feature offered by Afterburner giving usage percentage of each card in SLI. I got a tri-SLI 480 setup as well as a 580 SLI setup and the cards are scoring low on bench's and I see the card usage is in the 75% range a lot. Now, I also have a 690 that is getting 95% utilization so I "m happy there. I was wondering if older drivers might be better for the older cards as they are on the 304.79 betas, or any other suggestions. I'v moved the cards around into different comps and it doesn't seem to help. The motherboards are p-68 Revolution and the 480 cards and Rampage 3 and the 580 cards

Hi.
On some of your SLI system, you may be CPU limited and or memory bandwidth limited.

It happened for me in the past when I used a GTX 295 with a QX6700.
When I putted that card on my new ivy bridge system (while waiting for my GTX 690) the problem was solved. (always +-90+ % gpu utilisation.)

yea,It may be motherboard related cause my 690 got a lot better when I removed it from the Revolution and put it on a Rampage 4-bothsandy bridge. Also an ivy bridge won't advantage a sandy bridge on an older card

What are your scores and benches that are low?

580 SLI should get about P10,500 to P11,000 in 3DMark11 and a 690 probably about 14,500

With an o/c ed 2600k.. and the GPU at stock.. those are my guesstimates

Vantage was 41,000 and 43,000 and I have gotten 46,000 and 50,000. The tri sli . I'm looking aT Crysis 2 and Alan Wake and BF 3 running at 75 to 80 % usuage....the 580s seem better after removing and putting them back in but my 480 s still suck!

My estimates were with stock clocks as I said.

Congrats on the score I guess?

why would one estimate oc cpu and then stock gpu, it does not make sense

What rez are you testing at? Also have you tried setting them to max performance instead of adaptive in nvcp? Alan wake keeps my oc'd 580's at a steady 95-99% usage but this is at 1600p

Just upgraded to 2x 670 Asus DirectCU II cards from 2x6970s. Clean install Windows7. BF3 is smoother, but smoke and close-up explosions still bring down the FPS counter a fair bit, to late 80s from 120 ( I am VSYNCed), I was under the impression I will be getting butter-smooth gameplay with these bad boys. Using latest BETAs.

I am not sure if there any particular tweaks/settings I need to check up on, I havent been with the green team since 8800GTX.

Jeez, I feel I miss something in this life, how much do you need? 1000 to be happy?

What is more buttersmooth to you, late 80s? Or 90? Or 91.99? You feel the difference? Or 120 is surely better?

[Good God, I upgraded from ... to ..., now I lost 1.11 points in Vantage!!! Holy crap, these drivers and hardware is ****!!! I'm gonna kill myself now as I am not getting 500 fps as I expected!!!]

Don't get all butthurt if you didn't like my post. This forum has gone downhill lately with unhelpful muppets much like yourself.

Hahahaa! I could not agree more BladeRunner.

YES YOU CAN NOTICE THE DIFFERENCE.

Is that clear enough for you muppet? I have a 120hz monitor and when I can get up to 100-120fps BF3 is not only smoother but you can fly better AND here is the main thing, because their are more frames when you turn, you actually see more.

Yes that's right! You can actually make out more because you have twice as many frames as 60hz/60fps so you get more to your eye and can then make a better reaction/decision to what you want to do.

Got it now?

I see soooo many judgemental people on this forum and others saying you can't tell the difference. Well I want to lay that to rest right here, right now. YOU CAN.

BF3 has had crap performance ever since the last BF3 patch... I think DICE change something. I haven't been able to get a solid 60fps Vsync'd experience in BF3 in a while.

BladeRunner · 07-21-2012, 00:21 | posts: 1,865 | Location: Mayfair, London, UK

yeah, just checked forums,seems like a common issue, this is a shame.

just to touch base ,it was totally my revolution motherboard- I'm running tri sli with a rampage 4 and in Alan Wake they are living at 95 %-the 580s- one card does 86%-the 1st one and the 2nd does 95%-go figure-Thats an Asus DirII card
