sleeping dogs / mafia gpu or cpu bottleneck

jwmachon · 17 Sep 2012 at 07:52

3570k @ 4.5
zotac 560till

mafia maxed out physx on - 38fps
sleeping dogs extreme - 20fps

do these sound right for this setup is it a gpu or cpu bottleneck

thanks

Not to sure about the fps, but I can say that it's definatly not a CPU bottleneck!

What res are you playing at?

1920x1080

mobo is a z77-d3h

What program is best to run in backround to see cpu usage and gpu this is what i need to do isnt it

Thanks

MSI Afterburner is perfect for logging those numbers, u should be using it to max that gpu of yours as well

That sounds about right tbh. Mafia at high settings is quite demanding. PhysX doesn't really help. Dunno about Sleeping Dogs. Run an 3Dmark / Unigine / Cinebench with standard settings and resolution and check with comparable systems.

If you want better framerates, decrease MSAA, or use FXAA (post processing AA), or none at all, decrease tesselation, and variosuly demanding settings. And of course no PhysX, that can hinder performance.

Also, the usual suite of monitoring software. MSI Afterburner (which does real time monitoring, tweaking, AND video capturing), CPU-Z, HWMonitor. I use Windows Task Manager to monitor CPU cores and memory usage, it's reasonably accurate.

Does it sound like a gpu bottleneck whats best prog to check cpu usage or is it defo card

Thanks

Mafia 2 on my setup full settings will hit 60fps. So that olivier im sorry but your wrong.

My setup:
955BE
Zotac 560ti 448.

Try opening msi afterburner and task manager. Play mafia for a bit. Tab out and check the usage bars and temperatures of your graphics card.

Also keep an eye on ram usage. Could be an issue there too.

Well are we talking min fps or max fps, PhysX, MSAA. I know Mafia hit my system harder (not really graphically demanding, just poorly optimised).

was that with physx on or off tho this makes a big difference I had everything on full

I have 16gb memory

I did a quick test this morning and I think my gpu was at 100%

Testing for CPU/GPU Bottleneck

Hi,

Whats the simplest way to check for bottlenecking is it this

1. Load afterburner and task manager
2. Run Benchmark on game
3. check afterburner and task manager cpu

4 if cpu is at 50% and gpu at 100% = gpu crap
5.if cpu is at 100% and gpu at 50% - cpu crap

am i thinking right

Whats your specs please

trickynickyuk · 17 Sep 2012 at 14:17

Turn physx off your performance will increase straight away

Not necessarily. GPU should be at 100%. It means it's working hard, either giving you the maximum framerate it can, or it's bottlenecking. The CPU could be coping just fine at 50% cpu usage.

Usually, game cpu cycles are capped at a maximum frame rate (200 fps, whatever). Quake3 being the exception, where it can go well beyond that (and subsequently break down due to loss of floating point precision).

So if your CPU is maxed, and your frame rate is crap, then the CPU is bottlenecking.

if you get under 30 fps average without vsync :
- GPU@50%, CPU@50% then it's the game that's the problem (i.e. Guild Wars 2 Beta). This can happen via poor optimisations, single threaded update and render. or some dependencies between the two.
- GPU@100%, CPU@50%, then the GPU is struggling. Decrease graphical settings (MSAA, tesselation, PhysX, usually a good bet).
- GPU@50%, CPU@100%, then the CPU is struggling. Decrease stuff like viewing distance and physics (ragdolls, ect...).
- GPU@100%, CPU@100%, then your computer on the whole is struggling. Decrease everything.

If you get over 40 fps whatever the condition, then don't worry about it.

That's my take on the whole thing. With caveats that in some occasions, particular circumstances may vary.
