Bad SLI performance BF4

Something weird is happening.
yesterday at releaseday the game ram crap low fps. 70-100 fps
suddenly it ran fast +120 fps.. could play perfect with vsync on 120 hz.
today im back at 70-100 fps..
something is fishy here.
whats your experience with BF4 and SLI?

I am running newest nvidia drivers. clocked my 670 gtx SLI at 1267 core/3500 mem. my 2500K is running 4600mhz. Win 8.1 and 8 gb ram.

 

It works really well FPS wise (constant 60fps on Ultra @1200p) but I do get freezes which force me to kill BF4.exe. Has happened 3 times so far. Im trying with SLI disabled for now to see if that is the problem or not.

 

Its obvious Dice need to patch the game, there is also the sound that just doesnt work as it should. Sometimes you just hear silence, and 2 seconds later sound works fine, and then again silence? This game is very buggy, so we need to put pressure on dice/ea.

 

Soundbug is already adressed and fixed with next patch!

 

BF3 had the sound bug at launch too. My SLI runs fine, I always get a nice 70-120fps, no mad dips. Very smooth and enjoyable. Luckily I havent had any crashes either (server crashes aside )

 

Try the 331.58 drivers first, if not, revert back to 327.23 drivers, the 331.68 drivers, the sli will NOT work, revert back to 331.58.

Make sure you clean the drivers with Driver sweeper 3.2.0(picks up much more stuff then Driver fusion/DDU(Display Driver Uninstaller), But I would use thoses.

331.58 been working great most of the time, got a complete froze at one time.

In nvidia inspector, make sure you put sli rendering mode to auto select and not af2, af2, it wont use both gpus at 100%, it will just compensate one another, leave it at autoselect, works great for me, both gpu's 100%

 

My SLi runs fine on BF4 with great scaling, much better than BF3 (I've yet to see anything below 100 fps @ Ultra settings 1080p / 4xAA), but I have only two cards, so it may have to do with your tri-SLi setups I guess. Can you disable one card to make sure it's not that ?

 

No crashes since server patch R7 and:
¤ Running the game in x86 mode
¤ Disabling Origin Overlay

FPS is really steady at 60. Not noticed any dips to 40-50 yet.

 

Why are you running 32 bit?
and I assume you are running high res. since your only at 60 fps?

 

Running the 32-bit app since I read the day after launch that it was more stable than the x64 version and crashed a lot less. I could try to go back to x64 now that DICE released that server patch.

Yes 1200p @ Ultra with 4xMSAA, AA Post disabled and Vsync enabled.

 

okay vsync off you might hit 150 fps

 

Graphic performance is no problem here. I have good frames 2560X1440 and all Ultra settings. I have very pad sound errors tough, very annoying.
Second, i cant get anyone killed. Very frustrating. They kill me few shot, i may empty whole clip and can't kill enemy :bang:
This game is beta version at most.

 

same as the netcode need to be fix its killing the game play ....

 

SLI scaling is pretty good for me (with these settings) I normally run at 60 (adaptive)

Lowering Post Performance was key to achieving playable (no stuttering)



VRAM is at 1900MB.
Driver is 331.65

 

Do you think the hit detection could be effected for some users? I'm lucky and also have no problem running this on max setting's (2560x1440) with exception or SSAA on 100% but I'm using quadro drivers 320.92. I have also found it much harder to hit compared to playing BF3, its just since you have mentioned it.

 

I'm getting pretty good performance, but smoke is all flickery for me. Any ideas?

 

My fps are nice high.. But still feels laggy. Texture flicker as well.

 

What post process does anyway ? And Effects is related only to explosions or the weather effects too ?

 

the today patch gave texture errors for mulit-GPU users

Yeah same here, I was lucky up until now with the performance of the game but after today's patch every map I start is flashing like hell. Was looking forward to testing the new Quadro drivers that's out but it looks like it's benchmark time instead.
