Yeah, i was bothered by the fps difference between windows 8 and windows 7 and i may or may not dual boot partition with windows 8 solely for the game and windows 7 for my other games and general usage os if such numbers are still present in retail.

Not sure if i wanna shell out the cash for a operating system come January 16th when 8.1 preview expires on the 15th so i could get this game to be much more playable so hopefully the fps difference is a major bug that gets fixed.

I'd consider that as well. But I know that in another year, some amazing game will come out that NEEDS windows 9 or else it will suck. So i'll just let them get this forced upgrade garbage out of their system for a few years and then jump on windows 10 or something.

Battlefield 4 just got an update, supposedly fixes many of the performance issues.

Nope, just the game hanging at "Loading" with a black background when you actually are in the game already, but cant do anything.


It was happening to a lot of people. The performance issues still prevail.

what does the resolution scaling do ?
Click to expand...

It's how the internal resolution compares to your set resolution. If you use 200% and set the graphics resolution to 1080p the textures are actually double the size of your resolution and are downscaled, which makes them look better.

On the other hand, if you have serious problems running the game in Full HD you can set the scaling below 100%. The game will still upscale to 1080p if this resolution is set. The advantage would be that you can use your monitors or TVs native resolution (so the picture won't look blurry) whilst still having good performance (it's actually what the consoles usually do).

Edit: A nice video of BF4 played upscaled on an i7s iGPU. :)

So with a 3570k overclocked to 4.2, 16 gb ram, gtx 670 i am getting 100% cpu 100% gpu usage pretty much the entire time i'm alive. Anyone have any idea what the deal is?

If it bothers you, you could try not being alive so much. Theres a couple of hundred thousand players that could likely help you with that one :sneaky:

With my 3770k @ 4.5ghz, in a 64 player map, the game is heavily cpu limited. I have 2x 7970 running at 1440p. There were times where I was only using 60% of my cfx 7970s.

I am really hoping the beta is sucking down CPU because its a beta and has debug code running. The game runs a LOT slower for me than BF3, even if I set setting to lowest. So I am certainly CPU bound (That and the CPU is at 90-100% all the time), which I can expect. I have a 965BE @4GHz, not fast by todays standards, and only a quad. But I am seeing almost half the frame rate that I saw on busy maps in BF3.

Building a new system in the spring, but gotta make due with this for now.

I noticed gains in my gameplay using 8.1 preview but nothing like that wow.Betting this so called patch coming soon for windows 7 still won't make the game nearly as smooth as it is on windows 8......

6 days till beta ends, where the hell is the patch?

You mean the one that came out two days ago?

I am seeing 100% CPU usage pretty much the whole time and 90% Max on each 7950 in CFX @ Ultra settings @ 1080P with no vsync and the game runs like butt.... It's playable(40ish FPS), but not even close to being smooth. This is with the newest drivers 13.11 beta

Also, does anyone know why MSI Afterburner's OSD will not work with this game?

^ what he said, Rivatuner doesn't support 64 bit because of a lack of "need to".

Hopefully they find a need to add it now.

pcgameshardware.de is reporting huge benefits from Win 8.1 with the latest update:

For such performance diference from a FX6350 to a X6 1090T to be possible it means the bottleneck is on FPU, its probably the Havok engine bottlenecking everything, what happened to OpenCL for Havok?! DICE should have put pressure on them to do it already.

FPU is faster on Intel, so that whould also explain why it performs better on Intel CPUs.

I get 60 to 70 fps with a single GTX 770 and i5 2500k in Battlefield 4 with all details on Ultra, 4x AA and AF on High.

Nope, FX63xx performs like this due to issue the engine has with 3M(6 core) PD parts. You can see it here. FX6350 is 2x slower (yep, slower) than old FX4170 Bulldozer( that is 2M/4core part). FX6350 should be ~30% slower than 8350 in this game so roughly on par with 1100T. Hopefully the retail version fixes these serious issues.

Isnt it kind of weird that with all the effort AMD/Dice supposedly put into this game to optimize for AMD hardware that they borked the second fastest AMD cpu?

Well I have no idea what they did but bf4 is one of those very very rare games that have such an issue. Hopefully they fixed it with this latest patch.
