***THE BF4 BENCHMARKS THREAD***

What level/settings mate? I take it start a private game and just run around?

Just copy what we have done over the last page. Max settings FOV 80 and off you go

 

[ChrisD.]

Sorry mate, but what level and how do I start it?

Not played in ages!

Siege of Shanghai - Spawn on the Chinese side - Max settings - copy that run. An empty server is best

 

[ChrisD.]

Do I need an expansion pack for this level?

 

[Gregster]

No mate, that is part of the basic BF4 package.

 

[ChrisD.]

Yeah worked that out, I was trying servers with a rotation that included new maps.

1080p for 2 mins that right? If so I'm uploading to YT now.

 

[ChrisD.]

Angle isn't great.

 

[Gregster]

Nice one

 

[ChrisD.]

I'll do one in a bit at a less screwey angle with some GPU stats. Just installing Afterburner and will do a run in Evolve first.

**Possible SLI FIX!!!**

While lurking around reddit earlier I saw a post from a chap saying that adjusting CPU affinity on the fly greatly increased his frame rates in the latest AC and FC games. So I thought what the hell, lets try it with BF4 and see what happens, I had suspected nothing, its already a well multi-threaded game...

SLI users will be familiar with performance looking like this as of late...

Alt+tab out and run the affinity profile...

I also appear to have gained 9fps in the process too...

I am now wondering if the latest Nvidia drivers (*344 branch) are to blame for recent poor sli performance, perhaps its release to coincided with a windows update that did something to CPU and priorities?

Either way it feels smoother, frame rates are a little higher and the graph isn't going ape all the time. Good times

Nice result, not familiar with this affinity thing tbh. Any chance of a link to the original article mate. 9 fps is a nice wee boost.

Used this to create a shortcut: http://www.eightforums.com/tutorials/40339-cpu-affinity-shortcut-program-create-windows.html

Open game, alt+tab out, run shortcut, open game again.

Set affinity to all 8 threads with hex code FF.

Can easy set up a file for you if you want, just give me the location of your BF4 install

Not at home at the mo, just browsing on the phone mate. I'll have a look into it when back on the pc, I'm on windows 7 here but moving to 8 soon.

 

[pgi947]

Should be the same for 7 as 8, the only change is to check how many threads your system can run, which as its a 4C8T i7 will be 8 regardless, so FF

 

[thefogo]

Game still runs like garbage for me.
Not sure if Afterburner monitors frametimes correctly, but here's my frametime when playing.

 

[setter]

That looks shocking tbh, is it the same on the ingame performance overlay?

 

[thefogo]

I've not checked but I imagine so. Hard to tell though as it's frame hitching so you can't read the overlay. GPU usage on both cards frequently spikes down to 0-20%.

 

[setter]

I suppose youve tried the usual repair game, various drivers or perhaps a full os and game reinstall, bit drastic though. For a long time i had cpu spiking issues, similair to your pic on some maps. But gpu use has always been very consistent.
