Is anyone running BF3 with 5770's in Crossfire?

[ChristopherGillaspie]

I am wondering what fps you guys are getting. I have one 5770 and I am considering adding a second. I play at 1920x1080.

 

[happy medium]

just add 80%+ performance

I wouldn't bother. If you want more performance I would sell the 5770 and buy a single, faster card. For instance, you could probably get $70 or so for that card, used. Then, get something like a 6870 for $150 and you're only out $80, instead of $100+ for another card. You'll get roughly the same performance, only have to deal with one card and not any of the problems that a Crossfire setup brings. This is only coming from things I've read. I have not used a Crossfire setup before.

Example of your 5770 vs. 6870:

Im running two 5770's in crossfire with a 2500k@4.6ghz, 20-30 fps on ultra, not really playable though, although its fine on high and still looks amazing. You can pick up 5770's for about ***163;60-70 over here so its a cheap upgrade if you just want to make it playable, they eat pretty much every other game max'd out aswell.

Repoocekim, is that with Antialiasing enabled? AMD cards don't do well with AA in this game, use the post-AA on medium instead. Ultra quality should also use more than 1GB VRAM... I'm sure 5770 crossfire do well on High settings with no AA.

What is going on with the forum?

 

[Spikesoldier]

your performance would be less than a single 5870. so take some fps off the 5870 results and that should be where you would stand with the 5770 CF.

I'd actually give it a go. The user above reports that it can handle high. Tom's found that the 5770 was just behind the 6850, which is to say it's not getting thrashed (keep in mind this is single-player):

http://www.tomshardware.com/reviews/battlefield-3-graphics-performance,3063-8.html

I got 86% scaling going to 5850 crossfire. I don't know if you'd get the same, but 80% is a good guess, as Happy Medium suggested above.

Yeah, I noticed percentage signs being turned to gibberish earlier.

I am running two 5770s in crossfire with a brand new system 6 cores AMD with 4gb of RAM and the game is currently unplayable in crossfire. If disable crossfire i get playable frames at high settings with shadows tesselation and effects at medium. It's too bad this game performs way worse with two 5770s, I upgraded just for BF3 and i run the same settings as with one card and a dual core @ 3.2. The 5770 is now officially a joke thanks to AMD. Get a newer card.

Might want to go for a memory upgrade. Heck today (Cyber Monday) you can get 8GB for $25. I have no problem with 5850 crossfire in BF3, so I know it works, but I also know it uses a lot of system memory.

And welcome to the forums.

That is very true, when running 2 cards in Crossfire, one has to remember that all the help from the additional card must go through the PCIE slot, to the memory controller, to the CPU, be processed, back through memory controller, and back to the first GPU to be displayed... (theory is correct but terminology is probably wrong).

Therefore, your computer has to store an additional bunch of stuff in the RAM to be faster, and a lot more is going through the pipeline (faster RAM would help in Crossfire methinks?).

One GPU just has to compute & display, a second GPU has to do the same and then through your computer's pipeline.

Is this all making sense?

Actualy 5770's in crossfire will beat a 5870,and crossfired 5750's beat a 5850, even in early reviews.

"The CrossFireX configurations of entry-level cards are 5.2-7.7% ahead of the Radeon HD 5870 and HD 5850 at 1280x1024 and 3.5-5.6% ahead at 1920x1200."

Thats 3.5% without AA and 5.6% faster with AA

I'm sure today with better crossfire scaling, they would still beat a 5870 easily.

2 overclocked 5770's = a gtx570/gtx480 . thats not bad for cheap.

I use 5770 CF
It had been bought especially for BF3.
ultra -- cannot be played. Because the game stop time to time (may be it is not enough DDR, I own only 4Gb)
But high is good. Usally 50-40, some times 20 fps.
In GPU-monitoring 2xGPU load 50-60% (do not know why)
For my own experience with CF the game became more comfortable:thumbsup:.
One problem is HEAT, videocards very close -- almost lay on each other, so temp for high-position card can be more 90 degrees. If close [cover/case] of computer, even see colored artifacts D:.

Sounds like you need a side-mount case fan blowing on your GPU's!

Not only fan! I put away some piece from GPUfan-blower. It gives several millimeters between cards. So now temp 70(top)-50(bottom) degrees. No over-clocking of course.

 

[CaptainSplat]

Thanks for the info. I installed another 4gb of ddr3 now i can play bf3 at full ultra without motion blur or anti aliasing and i get 35-40 frames average with the 5770s in crossfire, I can even use newer drivers now it finally works like I thought it would with only 4gb. 8gb is essential for bf3.

 

[poohbear]

yep adding 4gb of ram to my system made a WORLD of difference. My 5870 couldnt handle it before without massive stuttering, but now its perfectly fine with 8gb ram. People say u need more than 1gb Vram to run it in Ultra, that's BS. It runs everything maxed out (but NO AA) and i get avg35fps in 64 man server with my specs. Its brilliant!

Misread post... removed a waste of writing.

 

[poohbear]

Ultra includes both HBAO AA and MSAA maxed out. The only bs is the claim to run in ultra as you aren't if you lowered HBAO and MSAA. Yes you may have ultra on the other settings, but the point is you aren't running in ultra if you lowered the 2 most intensive settings in the whole game which would have brought your card to its knees.

lol bring my card to its knees? can u please define that?? As in fps in the single digits? Well no it doesnt do that at all. I have a 5870 which is a beast. When i play i have HBAO on and everything else on Ultra, only MSAA off. I get about 40-55 FPS on a 64 man server in the Oman map (pretty intensive map). It'll dip to 37-38 when shit really hits the fan, but mostly avgs 40-55.

I just tested it on Ultra with 4x MSAA on same map with same server, i got avg 20-30 fps, dipped to 17 when stuff hit the fan but avg was 20-30. I'd hardly call that bringing my card to its knees. Personally i prefer 40+ FPS so i prefer to turn AA off and have HBAO on. Runs like butter and i couldnt be happier.

 

[skipsneeky2]

If i had a lower end card,i rather run high with hbao then ultra without hbao.

Hbao really makes everything stand out and setting aa post to low,hbao enabled my 2gb gtx560 uses over 1gb very quickly and performance is good.

My old e8200 system with 4gb of ram and a 6790 the wrong settings and i would run into vram limitation errors that would crash the game but i know the first thing to do was drop hbao,drop all aa settings and drop my settings to high just to stop the errors.

I suppose that's pretty playable @20fps... /end of debate

no the original "debate" was this:

Yes you may have ultra on the other settings, but the point is you aren't running in ultra if you lowered the 2 most intensive settings in the whole game which would have brought your card to its knees.

i didnt lower HBAO, it's on. Just AA is off to get 40-55 avg fps, dips to 35 when shiat hits the fan. with 2x MSAA it runs 35-45 avg FPS, and dips to 28-30 when shit really hits the fan. With 4gb of DDR3 it was UNPLAYABLE at those settings. it would stutter constantly and FPS would be all over the place.

What im saying is the 8gb of RAM was all i needed to run the game at Ultra with MSAA 2x. With 4gb of RAM it was a ridiculous stutterfest, unplayable even at high settings.

I clearly misread the part about no aa in parenthesis. My bad.

Thats my original quote right there.

It runs everything maxed out (but NO AA) and i get avg35fps in 64 man server with my specs.

now, can u read and understand? i specified everything maxed out, NO AA. & it doesnt run it @ 35fps, it runs it @ 45-50. Then u come back and say No AA isnt ultra, despite me SAYING I RAN NO AA. lol, now stop wasting my time, and read a post clearly before being redundant.

SILENCE FOOLS! SO ANAL ABOUT NOTHING JEEZ!

Anyone else get bad frame rates in ArmA 2? I can't run this thing overclocked with arma 2 and my crosshair IV had jibberish in the voltage setting in bios I don't know the special code to get 1.65v dram anybody know this secret language?
