Ok
I purchesed Vegas and Vegas 2 today with hopes that it is a decent game.

I have installed Both onto my PC and I am experiencing FPS Issues when shooting, getting shot or certain points in a map.

What I have tried:
Updated Drivers
Disabling one of the Cores so it ran off one
Defragmenting (After installation of both The HDD became heavily Fragmented)
Running it on Very Low Settings
Running in on Max Settings
Running CPU on Stock Frquency
(Neither Worked)

Is there anything i need to do in the Configuration?
To be Specific, It happens Mainly when Bullets hit walls and creates a spray.

System:
CPU: Intel E6600 @ 3.2Ghz
RAM: 3GB DDR2 800mhz
GPU: Radeon HD 2900XT 1GB
HDD: 250GB (150GB Freespace)
SFX: Onboard Sound, Realtek HD Audio

Please Help...

*FIXED*

After recieving Now Responses, I took it into my own hands.

C:\Program Files (x86)\Ubisoft\Tom Clancy's Rainbow Six Vegas 2\Engine\Config\BaseEngine.ini

*Make sure you back-up the Original incase you done something that cant be reversed.*

Go to D3DDrv.D3DRenderDevice

[D3DDrv.D3DRenderDevice]
UseTrilinear=True
LevelOfAnisotropy=2
UseStaticLighting=True
ShadowBufferResolution=1024
MaxShadowResolution=512
MinShadowResolution=64
ShadowResolutionScale=2.0
BlurBufferResolutionDivisor=2
DisableShaderModel3=False
DisableMultiLightPath=True
DisablePrecaching=False
DisableOcclusion=True
bEnableFastShaderCaching=True
MaxTranslucencyLayers=1
ShaderPath=..\Engine\Shaders
AdapterNumber=-1
Gamma=2.2

Also i seems like sound played a bit of a Role

[ALAudio.ALAudioDevice]
MaxChannels=2 (2 to 12)
TimeBetweenHWUpdates=15

I cant confirm it will work for everyone, but hopefully helps, it also stopped Desktop Crashing and MP Crashes.
