Relationship betwwen sound and FPS
« on: January 06, 2003, 08:01:31 AM »
Ok..How is sound related to FPS.  I am told to turn down my
sound hardware accelaeration to improve frame rate.  This
sounds logical, dedicate less cpu to sound, more to graphics.  
  But, the little help thing in the control panel\sound\audio\
performance section seems to imply that if I slide the
slider to the full acceleration, the cpu will be LESS burdoned by
sound, and the sound card to handle more of the chore.
  I have slid it all the way to both sides, and really dont
notice the difference in FPS.
  Also, I make (plagerize) alot of sounds and plug them into AH.
Alot of the sounds are in stereo, and quite a bit  bigger in
bytes than AH's sounds.  Is this a hamper to my FPS?  It seems
it would be, But I just dont know.  I usually get around
40-60FPS, but when I get close to a buff form, my FPS drops to
5-10FPS.  Espically if one blows up.  Sometimes my system is
crippled by a buff form low alt over an airbase dropping bombs.
  Freezes and slideshow and about 10 seconds for my system to
recover, even after the buffs and airbase are out of sight.
  Any ideas?
I go 1280x1024x16  I have tried to cut my res, but my FPS and
performance actually worse, believe it or not.
  Also, error checking on or off?
                   flow control on or off?
                   enable compression or not?
                   Mipmapping yes or no
                   palletized textures yes or no?

 p4 1.7
 768 sdram 133 <--i know iknow
 30.82 drivers (tried the 40.xx detonators, they suck for me)
 gf 4 ti 4200

All help or comments welcome

Turning down sound acceleration will not improve framerate.  You would only want to turn down sound acceleration to try to resolve issues with sounds cutting out.

Mip mapping improves the look of textures by reducing what I would call flicker, but will not improve framerate by enabling it.

Mip Mapping enabled will improve framerate only if you move your LOD bias towards reduced image quality/more speed.

Otherwise, leaving it disabled is better.

It'll only give about +3fps max.

I hate to say it, but its your early revision P4.

I have the same chip, a P41.7 with only 256k cache. though mine is mounted on a Rambus board with G4 ti 600.

No mater what res I run at, I always get the same FPS, 640 up to 1280. bottle neck is my CPU. Just take a look at the bench marks between the P4 1.7 and the new 512k cache 1.8. only 100mhz between them, but the differance is massive.

to double check tested on my father inlaws PC I built the other month, p4 1.7 256k cache but on DDR 266mhz board with a G4 ti 400. identical frame rates, only slightly slower at wicked high res, wich is to be expected because he gfx card is a touch slower.

Also I doubt your ram is helping, but this is not that great an issue.
