4870x2 + BF3

[lenne]

A little bump here...

I did sell my 4870x2 to a friend of mine and hes now running into scaling problems:

medium / small maps run just fine with xfire scaling well, large maps have severe scaling issues and are running with jumpy / low fps, disabling one gpu gives better results.

hes running a q6600 @ 3,5ghz and 8gb of ram and latest caps / drivers from asder.

afr friendly profile performs even worse, graphic options only make very little difference ( tested all from high to low )

did anyone else experience this ?

( i do remember my own rig running a q6600 @ 3,6 scaling / running the game perfectly )

my own guess right now that theres a pcie bandwith limitation of some sort but i still have to test that

[lenne]

Ok, i do now have a definite answer to the 4870x2 and BF3

As mentioned before, framerate, even on low settings wasnt really playable on 64 servers.

I did upgrade now to an 2500k ( @ 4,6Ghz for now ) and just to have a look at performance we installed the 4870x2

...

What a massive difference, all high but blur / aa NEVER dips below 45 usually sits at around 60 fps ( with highs of 130+ )

I knew it would make a difference but i didnt expect it to be that huge, i mean the q6600 was running @ 3,6ghz so i thought the problem lays somewhere else, but it most definitely doesnt.

Hi Bhudda here:

I registered after trying to search for a solution to this very same problem and I am some what happy that I am not alone.

Has there been a fix for this? After paying $20 for BF3 and seeing that it met my systems minimum requirements I went and got the game from Origin only to find that it runs exactly how you all have described.

I have

E8600 Intel Processor
DDR2 4Gig RAM
4870x2 1Gig connected to the PCIE 2.0x16 slot
Vista 32 Bit.

Drivers
11.10 with Catalyst Control Centre and CAP4

The newer drivers did not seem to solve anything. I have also followed the instructions to increase the memory size as shown here: http://battlelog.battlefield.com/bf3...4624714033242/

If anyone knows of a fix then please help a Bhudda out.

Disable the Teamviewer thats running as a process if you have it installed. You have to disable it 3 times to get it to stay off.

It was causing BF3 to load in a window and resulted in me getting only 30fps.

The solutions are already here Budda, ur processor is way underpowered for a 4870x2 and u dont have enough ram to run it.

The only solution for u would be to run it on just one gpu ( Disable cat ai or disable one gpu in the device manager )

Btw, turn off indexing and other vista memory system hogs, thatll help a lot.

I just looked at the back of my box even the 3000 series should run this game. If it says it should work it should work. And yes i still buy games in dvd jewel boxes...lol

As far as someone explained to me.... Directx 10.1 has the preformance features of DX 11 just not the "visual features".

Its interesting how the Nvidia requirement is just DX 10.0 whereas for ATI it is DX10.1.

So why were people saying you need a dx 11 card? I guess they didnt read.

This is because ATI already had dx 10.1 in hardware when nvid still had 10.0

10.1 implemented some performance features but dx 11 adds even more.

u only need a dx 11 Card when u want to enable tesselation which BF3 supports.

I've ordered a quad core processor now and installed vista 64bit over the weekend.

Playing campaign on low settings both my gpu's using msi afterburner report 40-50% usage accross both gpu cores but I get around 30fps and micro stuttering.

Which are the most reccomended drivers to use in 2012? Watching videos on youtube don't help as people are playing the beta game which wasn't properly optimised.

From the limited scenarios I've seen though, Nvidia DX10 cards seem to perform better than the DX10.1 equivalents from AMD...Other games supporting DX10.1 usually show advantages on AMD hardware, doesn't seem to be the case for BF3 though

It's a shame most sites don't test more old hardware, I had been interested in seeing for example the HD4800 series vs GT200 series today, to see which of them turned out to be most "future proof"

I have my doubts about AMD striving to improve performance on the HD4800 series today, but I guess the latest drivers always are recommended when using Crossfire

The drivers in this thread work great when used along 12.1 cap3. Both GPU's now run under load whilst playing BF3 online. I still need to get better FPS as I get massive drops, but hopefully when the quad core CPU arrives that will solve it.
