SLI and Battlefiel 3 gpu usage, what's the best set of drivers?

[whyscotty]

Reinstalled OS and drivers GPU usage back to high 90's

Well still no further with this, seems to run nearly as good on one card than two, tried a load of different drivers and in game settings, weird thing is that using the preset setting is that medium settings give more fps than low settings, might just sell the 480 and just forget about SLI now and in the future, it must be a game issue as others are experiencing the same.

You're CPU limited in multiplayer.

That along with the drivers maybe not scaling as well anymore for an older card.

So a 3570k @4.5ghz is all ready out dated?

No don't think so, a lot of people have said after the last patch DICE broke the scaling in bf3.

It's not dated but BF3 utilises Hyper Threading and that can release the CPU bottleneck in MP somewhat.

I've used an i5 2500K and an i7 3770K so speaking somewhat from experience.

Actually think of it this way...there are scenes that are more CPU demanding than graphic wise? I mean I wouldn't be suprised if there are situation that Tri-SLI GTX480 can do 90-100fps, but overclocked 3570K can only do 70fps, thus bottleneck occur...

Also lowering graphic setting resulting in lower GPU usage but no increase in frame rate would points to being CPU limited as well.

I run 2 680's on a 2500K @ 4.6 and only see a max usage of 85% in BF3 and assumed it was a CPU bottleneck but I wouldn't have expected your chip to do the same. Maybe others can confim SLI utilises the GPU's to the full?

it depends on what map as well i just checked mine on the AK night map and got 89% on other maps though ive had 99% espically when playing 64 player

is the difference noticeable between the 2 cpu's?

Also at my 2560x1440 60hz bf3 seems to be running a lot smoother than 1920x1080 120hz.
Maybe it would be better with 3 120hz benq's

With an FPS counter on - yes.

Without - no.

However, as the cost of upgrading for me was less than £100 for a new motherboard/CPU I just went for it as I don't like the idea of my £800 worth of graphics cards not going full throttle .
