Nvidia Titan Battlefield 3

[GregJA]

Hey!

Is it just me or is there ridiculous fps drops on certain maps (especially strike at karkand)_

specs:
Nvidia Titan 320.18
overclocked to 106% power target, 140+ gpu clock offset, 100mhz mem clock offset
i7 3770 3.4ghz
16gb ram
windows 8
c2 850w silent pro psu

bf3 - ultra 1920x1080

looking towards the middle of the map i can go as low as 50 fps! both in 64 players and in 32 player...

is it my rig or the map? (it also drops not as extreme, on other maps too at times)

I am just wondering if this is unusual and if there is a fix... thanks!

CPU bottleneck.

 

[GregJA]

ive checked and it only runs at 60-70ish % while the gpu runs in the upper 90s

 

[GIJoeMyGoodness]

Sounds like CPU. What processor are you using?

 

[GregJA]

i7 3770 3.4 ghz

 

[DeadlyRefridgerator]

It's not a CPU bottleneck, an i7-3770K wouldn't bottleneck 4 GTX Titans...

 

[GregJA]

hmm wonder what it coulf be then

 

[cookybiscuit]

Yes it would, any processor can bottleneck any system.

BF3 is a very CPU intensive game, you really should have gone with the K version to alleviate bottlenecks.

You sure nvidia control panel isnt set to like 32x AA or something?

 

[slamer80]

You should run this game near the -70 100ish fps or more. Dont listen to those who say its a cpu bottleneck.

 

[GregJA]

then what would it be if it aint the cpu?

I have a 1090t and i runs smooth, at only 3,7ghz

Your cpu is one of THE best, so it cant be that man.

 

[cookybiscuit]

I don't know why people don't think its not a CPU bottleneck. I'm using a overclocked 780 and 3570k at 4.5, CPU usage is above 80% on all cores, GPU is around 60% and getting dips to 80FPS.

As STUPID as it may be, have you checked your psu to make sure that the titan isn't downclocking because of a lack of power?

Dude, it might be true but he has a 850w with ONE titan, is HIGHLY unlikely....

 

[Fishwithadeagle]

I have seen some pretty crazy stuff and seeing that it is a 850 watt PSU, it may be dead, just staying alive though because of what it is rated at.

 

[GIJoeMyGoodness]

Can you install Hardware Monitor (http://www.cpuid.com/softwares/hwmonitor.html) and have it running while you game for a bit? Then can you report what your max logged temps are for the CPU and GPU? There's a chance you have thermal throttling.

 

[GregJA]

the psu is a m2 cool master silent pro 80 plus silver (whatever that means) I feel like it should be enough power.. as long as i connected the cables and whatnot correctly.

I am downloading and will check and post results soon

in case its too small:

Titan:
max temp 91C (60% fan)
0.887v

cpu:
max temp 62/65c

this was playing 48 players at ultra 1920x1080 on strike at karkand for about 45 min.

(I get same fps drops regardles of amopunts of players goes to 50 with 32 and goes to 50 with 64)

 

[GIJoeMyGoodness]

So you may be experiencing throttling. 91C is pretty damn hot and not what the Titan typically operates at. That may be your problem. Even if it isn't you want to keep those temps under 80.

That was from AnandTech. Try lowering your overclock or increase the cooling capacity of your case.

 

[GIJoeMyGoodness]

FYI: Furmark burn-ins peg the Titan at 80C so you shouldn't be hitting 90 on a game. Another site (LINK) showed the card sitting at 67C at load, and 76C overclocked.

Turn on v-sync. I have 2 Titans and they only run 40-50% when I'm playing Battlefield 3 at 2560x1440. It can't be CPU bottlenecking either considering I have an i7 3930K overclocked to 4.4GHz. At least with v-sync, you'll eliminate those dips as your GPU will always stay at 60FPS (or whatever your refresh rate is). It's the same thing with Borderlands 2. I only get 30% usage out of my Titans with it. You will also keep temps down with v-sync. I rarely go above 60C on either card when playing Battlefield 3.

 

[GregJA]

Yeh I thought it was pretty hot, I am planning on getting some better cooling here.
Although if I turn my fan speed up it goes in the 78-80 range and seems to still give me the same fps

 

[GIJoeMyGoodness]

Have you tried lowering the overclock and enabling vsync to see if that solves the problem as well?

 

[GregJA]

ok did so and now in the same areas the minimum it drops to (ultra, strike at karkand looking into the center, 64 players) is 59 fps (fluctuates 59-61 fps)

sadly now that its capped at 60 it doesnt feel as smooth as before
