Confusing bottleneck

Posted (edited)

Long story short; I've been playing sleeping dogs and there are times when the fps will drop well bellow 60 fps, even though the gpu usage isn't that high. At first I assumed that my i7 920 3,8ghz was bottlenecking my 680 but that's not the case according to this:

http://cloud.steampowered.com/ugc/846953284661366164/08CD506168191B1B0E8354BFB72678CBD289188E/ (feel free to inform me on how to add stuff to my gallery)

Max core usage 63% and overall usage 36%.

I would still assume that this is cpu related though, seeing as the gpu will never reach 99% usage, not even at the lowest settings. I've also identified the two settings which pull me bellow 60fps as; 'world density' and shadow resolution. 'World density' would make sense seeing as it's tied to the cpu (unless I'm mistaken?), but the performance impact of the 'shadow resolution' dose seem a bit odd to me, especially given the amount of vram I have to spare.

The only other possible culprit I can think of besides the cpu is the psu, but it's a corsair tx 850 watts (from a few years back) so I find it hard to believe that it could be the problem. That said; psus aren't my strong side.

Any input would be appreciated :)

EDIT: I usually play with everything maxed except for AA which I promptly leave off.

The PSU won't be the bottleneck, not at 850w

 

To be honest I don't really know but you could always look at the windows experience index (I know it's crap) and see which is the lowest.

sleeping dogs has issues with slow down even on high end computers, one way to improve performance is to run it in a window, rather than full screen...

Instead of the WEI, try PCMark.

 

Or even a 3DM11 run.

Funnily enough I actually just happen to have made a 3dm11 run earlier today http://www.3dmark.com/fs/457324. Although I don't really know what to gather from it? The overall score seems well enough, with a somewhat low physics score.

is your cpu doing the physics?

if so change it to your gpu

 

i mean physx

put an image up of your Graphics settings...

Your graphics score is kind of low... My 7870 scores higher than your 680...

 

It's prolly background programs or a bad driver install.

 

I'll reinstall the drivers and make another run in the morrow. Really though I'd be glad to find out that my 920 is holding my 680 back, it'd make me feel better about getting a haswell.

Sleeping dogs doesn't support hardware accelerated physx.

Would a picture tell you anything more than me telling you that I usually max everything except for AA, which I leave off?

Sleeping dogs nearly fried my 3770k on a stock cooler, i was hitting well over 100C running it, could very well be your CPU holding it back...

 

running 2 560's SLI i had to turn shadows down to normal and Ambient occlusion to normal too, along with AA...runs at a constant 60fps now on those settings

Bloody hell, is it overclocked?

It's not like my cpu is throttling, and as I said; it doesn't really matter what settings I use except for world density and shadow resolution (not counting AA).

at the time no, it was a little dusty though, after a clean out it was around 80C...Stock cooler not fit for purpose...

I assume your drivers and sleeping dogs are upto date?

Just done a little run of the game, for me it only puts the CPU at 35-50% load, most games don't put the CPU under full load anyway, even when they are struggling.

where it massively dips under 60fps... it could have run out of vram at that point in time

it might be worst case scenario but yer,, could happen
