Performance Issues - Whiplash (Possibly other games)

[bigsnake]

I'm am still quite new to PCSX2, I have used it in the past but for around an hr or so.

Ok so whiplash is quite a unpopular game to my understanding probally because it was almost banned for animal cruelty and what not but the problem is is that the framerate can drop from 50FPS (PAL version of the game) straight to 25FPS minimum just by looking in a certain direction (Sometimes the scenes are a little advanced). I was wondering is there anyway I could acturly help increase the performance of it ?

Oh, there was also a problem with sound, I've tried different latencies and plugins and even if the FPS is high, the music will keep cutting out and at least 75% of the time alot of sounds do not play. I havn't tried any other PS2 games out on PCSX2 yet but i'm guessing they should all work fine with my PC (Specs at the bottom)

PCSX2 setup :

Version 0.9.7 (3876)

Emulation Settings

All but Speedhacks and Game fixes at defaults

Speed hacks = Enable INTC spin detection, Enable wait Loop detection,mVU flag hack,mVU block hack.

Game fixes = EE timing hack, Skip MPEG hack , OPH flag hack.

Video

GsDX 3693 (MSVC 15.00 SSE2) 0.1.16 (Can't use SSE3 or SSE4.1 because I don't have an intel)

Direct3D10 (Hardware)
Interlancing = None

Allow 8 bit textures = Yes

Everything else is default

And then I have everything on sounds as default.

My specs are :

AMD Athlon 7750, ATI Readon HD 4870 (1gb), 4GB ram,Windows 7 32-bit

For info on the 7750 windows picks it up as a 2.70ghz chip but I am certain it was 3.20, rather it is 2.70 or windows is just having false readings (I noticed it does sometimes)

Thanks for any help, I would greatly apreciate it


I'm certain it has to be something I setup wrong

Use cpuz to post detailed pc stats, but if your cpu doesnt even support sse3 than speed dropping to 25 flps is totally normal for any game, with cpu you have

[bigsnake]

Well, my CPU could support SSE4.1, it's just the matter of the fact it's not an intel chip so it only goes up to SSE2. As far as I know SSE4.1 is avaible in later models of the AMD Athlon series.

I'll have to look into it more though.

Thanks for the reply

My specs are :
AMD Athlon 7750

an AMD Athlon w/o x2 or x4 making it too weak to run pcsx2.

If u have a problem and cant solve it your self then listen to what others say because apparently you dont know what u are talking about. your cpu does not support sse4.1 because it wasnt meant to support it which tells me right away your cpu is too weak for pcsx2, so dont make excuses, and dont give me a lesson on intel vs amd.

if u want help download cpuz its free and post screenshots of your cpu info on cpuz here

No need to get rude, vdgamer. Op correctly choose the SSE2 GSdx.

I assume that game is a more demanding one, since the settings are all fine.
Try to crank up the VU cycle steal to see if that gives you a huge FPS boost.
