Jumping parts of non-static objects (FF9, maybe in other games too)

[Cyric_ru]

There is a problem, when I play FF9 (i'm using ePSXe) all of non-static objects (like characters) have some parts that are jumping on the screen (changing their form a bit) and that's not looking well.

I tried to use different GPU plugins (PeteOGL, OGL2, some software gpu plugins and so on), was testing on my notebook and on my desk computer, but this problem always was chasing me.

So I decided to ask help on this board. The question is, does this is due to emulation aspect or am I doing something wrong?

And sorry for my english, i'm russian.


Here's some specs of my computers:
1) Notebook Acer Aspire 1522LM
WinXP HomeEdition SP2
AMD Athlon 64 3000+
NVidia GeForce FX Go 5700, 64Mb
512 DDR
2) Desk computer
WinXP Professional SP2
Athlon XP 1500+
NVidia GeForce FX 5200, 64Mb
256 DDR

this is a problem with all psx games. its cause the psx has no z buffer and cannot distinguish perspective properly in 3d. its been discusssed many times before and there is no solution without massive work for patches on each game which is unrealistic.

Of course, you're free to make a to-apply-on-iso patch for any game you want... although noone has done that yet.

Thanks for answer.
Thread may be closed then, I don't mind.

Cyric_ru, you have two choices here.

first thing you can do is just to accept your fate and try to ignore it. you can also turn down the resolution. the closer to the original resolution (320x240) that you go, the less noticeable it will be (until it disappears at 320x240).

darth sephiroth: there is absolutely no way to patch this. it's because the PSX hardware itself lacks subpixel accuracy. so it's completely a function of the hardware, not the game itself.
