Has anyone had any luck with the topic, im at a lost end can't get games to run smooth etc mainly for bf2 but just get frame drop and sloppy graphics running trifire 6950s and eyefinity. Thanks for any advice
 
Crossfire and Eyefinity has way too many issues, and the problem only compounds when you step it up to 3-way. I haven't had a locked silky smooth 60fps in a very long time with 2x5870's and a buddy of mine running 3x6970's has just as much grief. I've done everything I can think of to resolve the micro/macro stuttering issues that it produces but there just isn't a solution. You would have thought that after all this time AMD would have gotten their shit together but apparently not.

Bad Company 2 is particularly bad, especially if you enable vsync. Disabling vsync in games will help to even things out a bit but the problem never goes away. It's partially to do with the fact that the secondary and in your case tertiary adapter not receiving any display timing/refresh rate information due to the ports being inactive with nothing plugged in. AMD haven’t figured out a way to pass the display information to the other 2 cards through the driver which results in the refresh rate being capped at 120hz for those cards.

I'm on 2 cards in eyefinity and I don't have any problems, however, I don't play BC2 and I've heard that game is poorly optimized for multiscreen regardless of what manufacturer you use. Compound that with the fact that it's heavily favoring Nvidia GPU's over AMD and you have a recipe for disaster. I saw a review once that showed GTX 560 Ti's beating out 6970s. Dice no longer supports the game so don't pray for any patches. My advice prepare for Battlefield 3 which looks good so far on either side, even with surround or eyefinity.

DICE released a patch not more than a few hours ago :D
 
BC2 is renowned for not working properly with multiple cards, and while it's being patched still by DICE, anyone who uses the steam version doesn't get the patches until weeks/months later, so are sort of out of luck. It also didn't start as nvidia-biased but it certainly is now. Given how well the game runs with two HD6970s at 2560x1600, and considering the fact that microstutter is probably going to increase a bit when running multiple displays, I'm not surprised it isn't smooth on setups like 2xHD5870, that isn't enough rendering performance to get a decent frame rate, and 30-35fps plus higher than normal microstuttering is going to be thoroughly unpleasant. I would suggest at least three HD6970s for 5040x1050 with BC2, nothing less unless you're willing to turn HBAO off or cut AA down to 2x. At 5760x1080, I'd probably still turn HBAA off on a 3-way crossfire setup. 6/7-Megapixel Bad Company 2 at max detail, this generation, is really the domain of GTX580 Tri-SLI.
 
I own the steam version, it's patching right now. Has been for a few hours since I turned this PC on (slow internet).
 
Yeah but which patch :p

I also see it, but at 2023MB I'm going to wait until later to download it to save using up that much peak bandwidth allowance. It'd only take me about 8 minutes to download the patch (assuming steam servers weren't being slow) but that's almost an entire day's worth of peak bandwidth usage!
 
Hi thanks for the reply’s, I’m running them on a Asrock extreme7, i can hit 200fps on one monitor on BF2 max setting but hell breaks when going to eyefinity i get about 60fps av but the frames drop loads and you get massive amounts of stutter across screens, if i use crossfire 2 cards it runs at 70fps with little to no lag just a little bit of screen flicker time to time as on one card its flawless at 35-45fps..
On another note I had the extreme4 gen1 and that will run crossfire and eyefinity with no problems at all really. It’s just this lag when you play games and close windows like the box/window stutters slightly downwards to close: s
 
I had trifire 3x6950@6970 with my eyefinity setup and had a lot of problems.
Now i play BFBC2 with two 6970 DC II and no problem at all.
The third gpu core is no go for eyefinity.
On one monitor all runs fine with trifire but no with eyefinity setups.

Can you tell me if you use dvi to hdmi or dvi to vga cables, just something to try on my setup as i use hdmi and have ordered vga to see if it makes any difference.

Also did you get big frame drops with 3 cards? and do you need to use 2 crossfire bridges with 2 cards? Thanks again!

I have asus dc ii with 4 dp and dell u2311 so i dont need converter.
This solution does not have tearing issue.
With the third gpu core i had stuttering not frame drops.
I use 2 crossfire bridges.
 
Thanks!
im going to try a different displayport to dvi converter tomo see if thats the problem.
 
Just an idea, but have you tried going into CCC and under Overdrive, try forcing 20%+ on the Power Control Setting for each card. Your clocks could be fluctuating on the cards, which will cause stuttering.

I have 2x Powercolor 6950s and run eyefinity just fine, I use 2x DVI and one minidp to dvi active adapter for my monitor connections. As for crossfire bridges, you only need one for 2 cards and 2 for 3 cards. What kind of power supply do you have?
 
Ive noticed that dropping the framerate down to around 50 induces pretty nasty micro-stutter. I read an article about it but cant remember where the article was...but basically, your frame rate though averaging 50 or more, stutters because the cards are not completely in sync and your seeing that milisecond lag time manifest itself. If you can bring your frame rate up above 50 (at least for me) you should elimante most of the stutter (all for me). Though to do this in BC2 at eyefinity resolution, I have to keep AA, HBAO, and obviously, vsync off.
 
Well my tri-fire eyefinity experience in BC2 has been fine overall. I run in a 5x1 config for a 6000x1920 resolution. The one thing I turn off to have a good experience is HBAO. With it enabled the reported frames are good but it doesn't feel as smooth. So I run dx11 all high at 6000x1920, get 100+ fps most of the time, and the gameplay feels good.

Also all 3 GPU's are fairly well loaded.

And the patch dice released this week ensures no more CTD for multi monitor users :)

EDIT: it's probably also worth mentioning, since the above is my experience with 5 monitors, that when I have used tri-fire on 3 monitors (3600x1920), the performance in BC2 is exceptional. I can enable HBAO with all high settings and it runs smooth.

Try using Dxtory. Its a program that can cap fps at any number, I've found it has removed my stutter issues in a lot of games including BC2. Well worth a try for crossfinity users. Before I found it I was going to go back to single card :eek:

While it HAS reduced the number of CTDs it hasn't eliminated them for me. I used to be able to go a good 20 minutes before it would consistantly CTD now I can go about an hour to an hour and a half. This, though, is much better than nothing at all for sure.
 
Thanks guys¬

My power supply is a Antec Quad power 1000w

I'm getting screen tear when i move applications across screens like when i play games, just noticed if i swap a dvi to dvi for a dvi to hdmi when the system is running it stops the desktop tearing :s but not games..

I do think this is a motherboard problem down to card syncing as i have the Asrock extreme7 and as you prob no it has lots of pcie lanes plus gen3 support, i am 99% sure i didn't have this problem with the asrock z68 extreme4 board, lucky for me my mate is going to lend me the board back today for me to eliminate it.. crossfire would do me now after all the trifire problems

Just set my power to 20+ no change, thanks!
 
Too bad.

I have Tri-Fire with a 6990 + 6950 flashed and run all three at 6970 clocks.

I haven't had a single problem in any games, as long as they have a desent Crossfire profile......now Dead Island........that's a real PITA currently......I shelved it.

I've found BFBC2 runs at roughly 60-75 FPS and has no issues for me at all.....but I haven't played it in a while. I used to run two 580 GTX and had no issues there either and the performance was similar to my TriFire.

My resent games.....Deus Ex: HR, Dead Island(don't get me started),Hard Reset, FEAR3,Dead Space2.............all run very well in EyeFinity........:D

Im getting 60-75fps on one 6970 with max settings apart from AA at 2x 5760x1200..

maybe i should sell my 6950/70's and get a 6990 with my 6970.. qhat a piain , what motherboard do you have ? ta

I am having trouble with that.
I have three cards and you're telling me you can run EF on that game with full out settings AO included at that frame rate? I'm not buying it.

I use an ASUS Rampage III Formula and an i7 930 at 4.2 GHz.
 
Yeah I don't buy it either, a part of the single player maybe, but not multiplayer. That's the same sort of frame rate I get, granted with HBAO and 4xAA, but I use two cards, and 2560x1600, so that's 60% of the pixels, and 180-190% the performance. HBAO doesn't add that much.
 
While it HAS reduced the number of CTDs it hasn't eliminated them for me. I used to be able to go a good 20 minutes before it would consistantly CTD now I can go about an hour to an hour and a half. This, though, is much better than nothing at all for sure.

Are you running FRAPS, Afterburner, the Steam Overlay, or any other FPS/GPU monitoring utility? Those all can cause issues with Punk Buster that result in CTDs.

I've had good luck with the new patch on this end. Smooth sailing at 6048x1080, DX11, 4x AA, HBAO Off, everything else maxed. I don't know my exact fps due to the previously described fps monitoring issues, but it's easily above 60.
 
Yeah with no HBAO I reckon you could run three 1080ps off a pair of HD6950s. I'm just not convinced about five :p
 
Yeah fraps

i7 2600k @4.8

i will video it if like and youtube it lol.. i was shocked as i was getting 50-80fps with crossfire but lots of frame drop and tearing so i just set it to 1 card and get a steady frame raye im sure i seen 80fps in some shots :s
 
Yeah and when I averaged 45-50fps when I tried HBAO in quad crossfire I managed 100fps in parts too. What's the lowest you regularly see it. Try Laguna Presa and White Pass, I think those are where I saw my lowest frame rates.
 
not sure on the map but just got 45-75 on the ship yards.. but the av was 50 :) still good for a single card and its on the 6950 bios again i was getting better as a 6970..
 
Ya don't buy the max settings at eyefinity on bc2 with 1 card...I ran a long time with 2 cards and couldn't max settings in eyefinity...single monitor 19x12 sure...but not 6048x1200.

I DO use fraps...I'll try playing without see how things go.
 
I found out that because when you use a single card on the extreme7 board you use the 2nd pcie slot been GEN3 it boots your current gpu performance by 13% i think i read, thats why i get such good resuts from a single card other ppl have said this an TT threads :)
 
I can't see any major cooling issues there, if that's your system, so I think that can be ruled out of any potential issues.
