FPS problem with fog

tinker20 · 03-23-07, 05:06 AM

Hello,

I do have really big problems if the gameengine has to calculate “volumetric fog”.
This occors when weather turns bad, like rain and fog.

As soon as thus in the game happens and weather effects emerge, I cannot play no more in the external perspectives. Frame rates sink then under 5 fps.
Really unplayable.

There I must turn the weather effects off in the options menu, then it runs again liquid.

Too bad, that with turning of the "environmental effects", those loved effect that you can see through the water is deactivated, too.
But those water effects don´t slow the game down, only the fog does.....strange.

Without this effect it looks not much better than SH3, my judgement.

System is a Pentium 4 with 2.6 Ghz.
2 GB RAM
Windows XP
Radeon X1950 XTX APG grafics card with 256 MB RAM.
8x AGP activated.

I have somehow the feeling that the fog effects go extremst on the CPU (pentium processor)

Do you have any ideas, how to solve this?

Hallo,

ich habe extreme Probleme, wenn im Spiel das Wetter schlecht ist und der Grafikeffekt "volumetric fog" eingesetzt wird von der Engine.

Sobald also im Spiel Nebel und Wettereffekte auftauchen, kann ich in den Außenperspektiven nicht mehr spielen. FPS sinken dann auf unter 5.

Da muß ich dann die Wettereffekte in den Grafikeinstellungen abschalten, dann läuft es wieder flüssig.

Ziemlich doof, daß damit der Effekt wo man durchs Wasser durchschauen kann auch abgeschaltet wird. Wobei ich ansonsten den Effekt anlassen kann, und ich kann trotzdem flüssig spielen.
Aber sobald Nebel auftaucht ruckelt es wie ne Diashow und ist unspielbar.

Ohne diesen Effekt sieht es nicht viel besser als SH3 aus, meines Erachtens. Das nervt mich ziemlich.

Ich habe irgendwie das Gefühl, daß die Nebeleffekte extremst auf den CPU gehen.

Was meint Ihr dazu?

Have you tried turning off other programs in the background? From what I've heard that fog really eats up the juice on your CPU.

Hi,

I turned every other programms off, while playing SH4.

It really seams, as if my cpu is a bit too slow for the game...

Any other ideas?

I searched the internet also, but I couldn´t find any info wether this fog effect stresses mainly the GPU or the CPU.

I've noticed my fps are halved in fog as well, but as I've got a 7950GT, that just means going from 70 fps on the bridge to 35

I haven't really looked into it, but I believe there is separate effects file for volumetric fog. If it's in plain text, there may be some options to tone down the detail, without impacting the rest of the environmental effects.

Also, have you tried adjusting your partical detail slider in the graphics options?

Maybe a modder can make the volumetric fog fx file smaller or even transparant to reduce the huge impact on the FPS.
I'm not a modder so I don't know if it's even possible.

Same thing...unplayable with fog...
