hello guys.i have a low fps in DBZ BUDOKAI,i get 35-60 when in the menu but in fighting i get 15-20.Why?
my system:
cpu-cor2due 6400
memory-2gb
video card-7600 256mb

Your video card is weak, plain and simple.

and DBZ is a one of these low fps games.
Try faster and compatible games like FFX or Kingdom Hearts.

Not sure which 7600 you have but I need to OC my 7600GT to the levels in my sig to get it running at around 35-40fps in fights.

so what card i need to play this game with normal fps?

if the game is GPU dependent, what it seems, then you will need a 8800GTX

your getting that fps in DBZ budokai?

and i did oc to my card 590/1600

im curious why ppl are like its cpu and gpu dependent lets look back on the dreamcast emu null DC vs chankast , ppl used to say the DC emu's were cpu limited/gpu limited on games but u know what we find out ppl just needed to code it correctly to get games running at normal speeds i think thats whats gonna happen with pcsx2 also, cause what the ps2 cpu is a what 300mhz and the vid card is a sup par 6600 gt? with a whole 4 mb of vid ram!!! (plus the hardware was better in the dreamcast but we get fuller emulation in the null DC why is that? , soo my point would be is that don't worry about FPS when the pscx2 team finishes doing their emu correctly it will prolly run full speed on a P4 (lmao maybe)

Umm, a Dreamcast is no where near as powerful and complex system as a PS2. My subjective opinion is that PCSX2 is even better optimized performance wise than nullDC/Chankast (No I'm not dissing these emulators either, I'm very amazed of them but there were more info for DC available and you won't neccessarily have to take advantage of all features which contributes in performance increase to get playable speeds on today's hardware). You wouldn't even get decent speeds in any games on a PS2 emulator if it wasn't very nicely coded, you really need to take advantage of every possible feature the computer system have in order to stand chance of getting decent speeds which is what PCSX2 team have been doing. But I'm sure they would be able to change the code quite dramaticly to have even better performance if only there were some accurate PS2 architecture manuals out there but unfortunately the info is very limited so lots of trial and error attempts have been made by reverse engineering to achieve what it is today. The newer the consoles gets, often the more limited the info about the console gets and the ever growing complexity of console hardware attributes as well to make it only more difficult. Unfortunately the details about the console hardware/architecture and how much the console architecture differs from our computers are among the major factors of which affects the difficultiness in coding an emulator. There's a reason that there's only 1 working PS2 emulator out there today, not many coders have what it takes to code a PS2 emulator based on the current situation. :p

If above was boring to read at least understand try to understand these points:

1) PS2 is quite a lot more complex than a Dreamcast, so a perfectly coded PS2 emu will still require significantly faster computer than a perfectly coded Dreamcast emulator.

2) Console architecture documenting availability plays a major role in the final result of an emulator project

3) It's stupid to compare apples with oranges. There's a huge difference between how the PS2 architecture works compared to computer architecture.

4) Look up more info about the console specifications and how it actually works before trying to compare them.

If you take into consideration various coding techniques on PS2 games, graphics in later games have become more complex, and therefore the calculations thrown at the EMU become more GPU dependant, as more and more GPU based code is being simulated, you'd assume your gpu has got to work harder, hence the better GPU you have, the faster it will run.

Its not the EMU at fault, it is doing it's job by allocating GPU specific code correctly to the GPU. If you have a crap GPU, then you wont expect the code to run at a fantastic level.

Also, its the CPU that tells the video card what data it needs to process, the slower that is, the slower the GPU can work etc...

So, sorry to disagree, but its not the EMU at fault, it is doing its job properly. Sure you can code PCSX2 to be 100% efficient, but you are emulating a 300MHZ RISC based EMOTION ENGINE here not a typical X86 Cpu....

read into stuff more before you go out dissing the EMU, a lot of people put a lot of hard work into this. (Its the feeling i got from the post lol) P.S the dreamcast compared to the ps2 is like a celeron to a core 2 duo, no contest.. lol

thats my two cents, and i may be wrong on some terminology ;),

***edit: - no hard feelings, just read that post, and i sounded like i was moaning lol! sorry if i came across as a 'flaming' idiot :P

i wasn't dissing on the emu i was only pointing out the fact that pcsx2 can and will run faster once they learn more of the ps2 code etc (which is what we see that happening with nulldc vs chankast) and sorry to say yes in some aspects the hardware in the DC was superior to the ps2.... Dc supported more video ram supports native anti aliasing should i go on? (btw PCSX2 is my savior)

His gpu is bottlenecking the Intel Core 2 cpu, if only he had a 7900 (Nvidia) or the X1900 (ATI) series then it he would most likely to get better fps. BTW, the 7600 series isn't all that great if u compare to today's modern GPUs ;)

You're still missing the boat. The PS2's hardware was a feat at the time. Even a 3.5Ghz Core2Duo is about 1/4 less powerful then what the PS2 could pump out. (I know plot posted those stats around here somewhere.)
