CPU Bottleneck?
#1
Hello,

I have tried running the Final Fantasy 12 (XII) using the Hardware DX9 rendering, and what i see is that I am getting around 80% of the FPS, and 99-100% of the cpu usage.

When I run FF-X I get around 60-70 CPU usage and 100% of FPS (ie, running full speed emulation).

It turns out FF12 is more CPU intensive.

The main question is: Is my CPU really a limiting factor here? I have expected an i7 to be enough to run the emulator full speed, but anticipated that my GPU could be a bottleneck. But it turns out that the CPU is a bottleneck. Is it just me or really it is the case. People who have a better graphics card than me, please comment on your situation. Does better graphics card help improve the situation? What about DX10? DX11?

Running the latest beta (1888) with the latest DX libraries.

System: i7 920 @ 3.2Ghz , 6GB 1600mhz DDR3, Geforce 7800GT, Windows 7 64bit
i7 @ 3.2Ghz /w Noctua
6GB Dominator 1600Mhz
5770 Vapor-X
1.5 TB Raid 5 /w 3ware 9650SE

That graphic card is weak get a 8800GT or a GTX260/275 and use hardware DX10 Renderer. Your CPU should be enough.

Are you referring to the CPU usage on the title bar of the PCSX2 window? Or are you referring to CPU usage from Task Manager.

If it's the former (most likely), then you are in fact limited by your GPU. It actually measures GPU utilization rather than CPU usage contrary to the name. If it's the latter (which I doubt), then it would seem that you have other issues, such as background programs etc. since an i7 @ 3.2Ghz definitely should be enough.

I'm banking on it being the former case, since it would make sense that you are limited by your 7800GT. Upgrading to a DX10 capable card (high-end 8 or 9 series Nvidia card, GT 200 series Nvidia card, or ATI 48xx or upcoming 58xx cards) should boost performance since you can run in DX10 mode.

For now, you could stick with Native resolution to gain some FPS.

Do you get full frame rate with your GF 260? Have you tried FF12? Thanks for the earlier reply, but more in depth reply would help.

With an E8300 @ 3.6Ghz and an 8800GT, I get full speed so far, though in some of the cutscenes it drops slightly to between 47-50 sometimes (which is still full or near-full speed).

Yes, I was refering to the title bar CPU usage, which turns out is the GPU usage. Thank you (and others) for the swift and detailed replies.

I run all my games perfectly on my GTX260 sadly i don't have FFXII yet, but i'm sure it would run nicely.
