pcsx2 and FF XII IZJS

MutantJohn · 2013-07-17 22:17:46

Hello All,

Here's the parts in my computer:

CPU: AMD Phenom II X4 955 Black Edition (@ 3.2 GHz)
GPU: nVidia GTX 460
RAM: 8 GB @ 1.6 GHz

And I'm running Final Fantasy XII IZJS through pcsx2 and I feel like my computer should be able to handle this game but I barely get over 30 fps. In fact, the only way my fps goes up is if I use the game's built-in 'turbo' function and then my fps goes up to like maybe 45 which is a lot more playable.

But I'm going for 60.

Here's my pcsx2 settings :

Video : ZZ Ogl PG 0.4.0
Bilinear filtering is forced
Interlacing is Interlace 1
Anti-Aliasing is 16x (note that changing these settings does NOT increase my fps at all, i.e. lowering them does not work)

GS settings :
Frame skipping is disabled
Framelimiting is enabled

GS Window :
Widescreen (16:9)
Zoom = 100.0

Speedhacks:
Enabled
EE Cyclerate = any value, doesn't seem to matter (1 to 3)
VU Cycle Stealing = any value, doesn't seem to matter (1 to 3)
Every speedhack but fast CDVD is enabled (INTC spin detection, wait loop detection, mVU flag hack, MTVU)

Is my computer not good enough? I was assuming that it would at least be able to handle a PS2 game.

Note that my emulation is working well. It's stable and it plays without crashing but at the same time, 30 fps isn't exactly playable.

My GS usage is always like 100% but I swear it cannot be the hardware. The games I actually can play w/ this thing are so much heavier than FF XII should ever be but I'm not sure.

Bump.

Does no one here emulated games? T_T

It's unfortunate, but you may find performance better under Windows.

Have you tried any other games, or any other conditions (like playing under Windows) to rule out the game itself? It's not unusual for console games to have their framerates throttled at the software level.

Software emulation of a system, especially a complex one like the PS2, incures a lot of overhead. The PCSX2 uses some advanced techniques to speed up emulation, such as dynamic recompilation (for various processors inside the PS2), but still, emulation will always be a lot slower than the native hardware. If you're interested in the specifics, I'd recommend researching how exactly emulators are written, perhaps start with something like this? Only when you actually get in to the coding of an emulator will you truly understand why exactly they tend to be so slow. If you're not at all interested in the technicalities, just know that software designed for a specific purpose usually performs worse than hardware designed for a specific purpose.

Also, some games perform much better than others, I find. For example, Final Fantasy X can run at at least 80 FPS on my system, but some other games barely hit 20. It's just the way it is.

Noooooooooooooooooooooooooooo!

Lame. Lame.

Oh well. I still have .iso but I lost the swap magic stuff for my PS2 so I'm never going to be able to play this game. Oh well. It wasn't that great anyway. The class system didn't really mesh with he Zodiac anyway.

Is not ZZogl heavily under dev and not-so-ready at this time?

Try gsdx in opengl-software mode as video plugin, it should/might give better performance if your processor handles it, though there is no fancy internal upscaling.
Works fine for me in linux at the moment.

Arch Linux
