7970 couldn't do that? I have a 7850 and a horrid AMD A8 5500K CPU and I rip through BF3 ultra with about 60-70 fps? Something is wrong with your PC if you're using a 7970 and can't get 60fps on BF3.
 


Then you lowered your settings. BF3 hardly runs @ 100 fps on a 7990 at max'ed settings @ 1920x1080

An apu!!!! are you kidding me?
 

Yes an APU? Your point is? and no, I didnt lower my settings I have them on ultra and I know what frames I get?
 


And maybe you should reread my post because I cleary said it was on ultra
 
The output is very crappy or the games just crash on start?
Well, never seen such a problem. Never happened with me. 🙁
Try removing any CD/DVD's from PC and remove any USB HDD's or Flash Drives and check for loose cables or too much CPU Usage.

Yes, the main reason can be a process eating up too much CPU. Open Task Manager and check for CPU Usage AFTER you run those games. Then if no such process found, open the resource monitor and try. Then check if your 3D Vision is enabled because it eats up GPU Memory. (3D Effects are toggled off) 😀

I am generally good on problems on Nvidia and Intel. No experience on AMD 🙁

EDIT - Also try re-installing your OS. I re-install my OS every time there is a problem like this. :)
 
Might be the CPU that's bottle necking your system. Amd's Bulldozer CPUs have always sucked and always under-performed the processors they were meant to replace. Always try to avoid BullDozer CPUs at all costs. But if you can't change out the CPU try to keep the tasks running at the same time at the minimum.
 


Ok so contrary to what some of these people are saying, none of your specific parts are "bad" your cpu is fine for gaming and your gpus are fine as well. (YOUR CPU IS NOT THE BOTTLENECK lol, despite what people are saying, you might only be losing 5-10% of your maximum possible fps from those cards due to a slightly slower cpu)

The power supply MAY be a problem for a crossfire amd solution however, but may not be the problem (is the only thing i can see that might be wrong from the spec sheet). From what i have read, for crossfire or sli on these higher performance cards, you generally want a 750 + watt power supply. The only reason i say that this MIGHT not be your problem is that under max load those cards might hit 200 watts each, with your cpu hitting i think 77-80 watts (might be higher as i am used to the intel power usages.. Everything else in the system will be using negligible amounts of power after those parts.

Otherwise your best bet would be to do a clean install of your whole computer and just start from scratch.

From that point, installing only one of your gpus at a time and testing each one would be wise., then perhaps checking that your drivers are up to date is your next best bet, as amd has only really recently gotten their drivers for crossfire to an acceptable playing level.

If the above two options do not work, then there is some other point in your system that is causing the decrease in performance purely due to malfunction. If you don't mind paying 60-120 $, take it to a computer store and they should be able to identify the problem.

1. While those gpu solutions may work better, he already has the two cards and it would be unrealistic for him to do so, especially with amd FINALLY stepping up on their crossfire drivers. (plus i think his 2 cards will out fps the 770, and we won't talk about frametimes here as it isn't relevant since he already owns the cards
2. 8gb vs 16gb there has been quite a few benchmarks proving that you literally may not even see a 1 fps increase
3. I do agree with you on the psu. Crossfire on a 650 watt is a little much.
 


Just curious, but you do mean 1080p, all details and AA maxed right? because that gpu will put out less than 20 fps under those conditions (1 card) I think 14 was then benchmarked number. 14fps is unplayable no matter who you are
 


People need to start specifying the exact settings you are gaming with. Simply saying ultra implies all bells and whistles turned on, which the 7850 will not push out those numbers at. Fully maxed, AA included, the 7970 should push over 60 fps (buddies did 60-80 when fully maxed and OC'd) while my 680 at the time under water did 70-90 with a flashed bios and some serious overclocking
 
Well im no expert but it is deffinatly NOT your processor, up untill last month i had the same just oced to 4.4ghz with a 290x and I had zero problems with anything, and im even running 3, 32 inch monitors. Charts with the 8120 vs intel dont prove anything unless youre running the exact same set up. Ive destroyed intel i5's with 770's and sli 660's. it all comes down to how you set em up.

Another hint.... Dont take advice from Intel users... its useless
 
1.use 1 video card, hate sli/cfx because of driver/stuttering issues
2.use 2x4 ram not 1x8-maybe map isn't loading fast enough for the computer?
3. SSD? your hard drive may be too slow for loading
4. are your SATA cables OK?
5. change gpu cfx to x8/x8, not x16/x16. the difference between the 2 are miniscule(less than 1%) and has less issues(personal experience)
6.change your cpu to piledriver instead of bulldozer???

7.?????
 
Hey! I found out something which could be the cause - I was just trying out overclocking drivers throughout the web and then there was one like which I mis-setted a bit and it locked the FPS Rate to 1 FPS. Check this out once again and then, get a pirated Win7 OS from your local market and try to run all those games. I bet it would work.

(I know there's a lot of problems in setting up another OS, but for $1100, It's worth it.)

And if this doesn't help too, get your PC dismantled and re-built. Some part of your PC Must be placed incorrectly.

{[(Well, I don't see any reply form user "minnidoffa" and this could indicate that the problem is solved or left as it is. :\ )]}
 
I would personally recommend AGAINST a pirated operating system, as these come with their own problems. The problems make the $100 for the operating system worth it in quite a few cases, and yeah, i think he either gave up or isn't following this anymore
 


So even if they are optimized for Intel CPU's and Nvidia GPU's that doesn't mean AMD products won't work. Also AMD products are almost always cheaper until recent when the prices skyrocketed due to bitcoin mining.
 
650 watt of psu isnt enough for your 2x7850 upgrade your psu 750 will do but go with 850 silver or gold certified hope this helps :)
 
Hey man,there is problem with amd processors and radeon gcards. When you install Catalyst Software start it up and in options you have performance tab. Click on CPU Performance and you can set how much cores you want to use effectively.Max cpu performance and you are good to go.
 


Hello minidoffa,

Here are my findings, you have a 2 GB GDDR5 card (or two cards making it 4). 2GB of vram should take you through all modern games on at least medium to high settings. You should not be having any microstutter or much lag. Therefore i can debunk the graphics card as a problem. The main problem i am looking at is CPU power. Some games a very heavy on cpu power and light on gpu power. Intel Processors deliver, they perform much better per core for single core games. Also, check the max power throughput your motherboard alows to the cpu and gpu.
 
for many games you need to enable crossfire in the catalyst control center for things to really work the way they should. Also microstutter is common with dual cards, no matter what company you have for your gpus
How to get Crossfire going:
1. install latest version of Drivers found Here
2. reboot
3. open up the AMD catalyst control panel
4. go to 3d application Settings
5.add a profile for AC4BFSP.exe or AC4BFMP.exe
6. leave everything as is except for amd CrossfireX Mode set that to Optimize 1x1
7. save
 
If you have the time, reinstall windows. That basically gets rid of any software kinks or possible problems. If reinstalling fixes it, then you found it.

If it's still buggy, its a hardware issue. The FX-8100 series was not the fastest cpu but will get the job done. I think your motherboard has built in overclocking. If it does, try that. Remember if it refuses to boot after an OC'ing attempt, and all else fails, pull out the cmos to reset the bios to stock.

Try older drivers from amd. That might sound weird but sometimes running beta drivers can be unstable and not work properly on newer games.

It's also possible for one of your 7850's to be a dud. Test it by running one card solo, then run the other card solo and if there is any major (15-20 fps) difference you have your issue. Could be one was thermal throttling.

If everything fails, and you're running bone stock windows with amd known stable drivers and the framerate is still unplayable where it should be playable, remember the weakest link in that rig is the CPU. It may be 8 core, but it doesn't have the proper architecture that the 8300's and other visheras do.

Keep fiddling! I'm sure it'll be something really obvious! Post back with more info on how it's going.
