BF3 Performance on SLI or Single Card Setups

[EvilJoker]

You still didnt answer his question.. How much AA do you have set?

1600x900 is a low res so I would imagine 1GB would be sufficient.

Yes.. its set to default setting on ultra preset. 4x

EarthDog.. PMS today?

I had no idea that changing the default setting changes the AA. Usually thats independent...hence my poking you to answer the question.

Ahh good ole BF3.

Before it came out I built my rig around the recommended specs which were clearly BS.

6950 2gb. 1055t AMD. 8 GB 1333.

Performance was awful. Couldn't even turn on AA without getting dips to 15 FPS.

I went through hell with this game.

I tried 2 AMD CPUs - 1055t and 975 BE
2 AMD motherboards - 990FX and 870t (i think)
Switched to i5 2500k with single 6950 2gb - performance was a lot better...but not constant 60FPS

Dual 6950's 2GB - Solid performance. Major Driver issues - Play a single map for a while then once a map change occurred my drivers would crash forever. Had to reinstall manually in safe mode every time
Dual 6950 2gb was nice and lowest FPS on ultra I saw was 50 in intense situations. There was stutter also sometimes.

Got rid of both 6950's and bought a single GTX 570 2.5 GB.

Performance was really good. But even at ultra and 4xAA it did struggle.

Finally switched to my current setup with 580 3gb. I have the game almost maxed out. Everything 4xAA, deferred high. Motion blur. All ultra except for Shadow and Mesh on medium and SSAO instead of HBAO.
I get solid 60FPS and lowest would be 53 in intense situations.
Very smooth game play. Not stutter. Smooth as butter.

That is a thread I started for my VRAM usage. Varies from card to card. I used 1.9 GB max for setting I just described.

For BF3 I typically get 45-55 FPS depending on what is happening. I play at 1920x1080 in Ultra as well.

GPU is Sapphire 6970.
i5-750 at 3.2
8GB GSkill DDR3-1600

According to Fraps

At 1100 core I average 50fps on ultra at 1920x1080. At 1200 core I average 57fps.

You need a sig DK... Mindreading is NOT my thing.

I have one ED. Just doesn't get shown when i post from mobile

The beast is going on chilled water today so we'll see if she can break 1300 core

if you kill msaa or even set it to 2 your frames will nearly double ... and tbh i almost think its clearer /less blurry off?

 

[EarthDog]

It doesnt double.. no way, but it is an improvement.

 

[EvilJoker]

Yea.. i dropped it from 4x to 2x and it did and motion blur off. it did keep more stable FPS.. like 47-48.. witch ant to bad from these older cards

 

[Cheezewhiz]

I just got my second gtx 580 3gb....BF3 = SEX

 

[EvilJoker]

DO you really need 2 GTX 580 to play on ultra? Im not asking a smart $$$ question, Im really asking.

 

[EarthDog]

His standards are incredibly high like MIN FPS of 50-60 iirc.

 

[Shadowmonk]

With memory less than 1gb on your SLI setups i would probably use Danoc's FXAA injector to replace the msaa/post proc AA. Should get better performance and a nice visual boost. I know with all settings maxed @ 1080p
my 7950 crossfire is burning 2.2gb vram, without the injector its near 3gb.

I'm an FPS junkie as well! Can't stand stuttering through a game.

That was going to be my exact response as Earthdog has seen how anal I cant get about FPS. I cannot stand Frames dropping below my refresh rate. I like locked 60fps. Now it never drops below that. Never its simply amazing.

Dual 580s for the win.


But ya a single 580 is good enough.

I just hate experiencing 60FPS during a certain part of the map and then all the sudden I am at 50 FPS. That rapid drop in FPS is what I cant stand.

 

[EvilJoker]

Danoc's FXAA injector?? What is that.. ive never heard of it?

 

[EarthDog]

Not trying to dump google on you, but I cant get to "games" from work.

This sounds like myself! I once built a rig with two GTX 570's just to play Hawx 2 on a 1680 x 1050 monitor. I was getting like 200 fps! LOL

 

[EarthDog]

Funny... HAWX2 gets 200 FPS on a single 580 anyway!
