2. Settings description


2.1 Reverb

2.1.1 Quality level

	This setting controls quality of reverberation. 
More quality level, more CPU load. In Vortex Tuner 
added undocumented, 5th level of reverb. After 
rebooting of computer or changing values in Vortex 
Control Panel this setting falling back to documented 
value. Provided Vortex Tuner Agent must be placed in 
the startup folder to restore Vortex Tuner's 
adjustments every startup. 

2.1.2 Base and Offset sliders
	
	These sliders change base and offset of the 
reverberation. Currently under testing.

2.1.3 Buffer Size
	
	This is size of 4th reverb DMA subbuffer. It 
appears to be that this is the buffer for reverberated 
wave data. Bigger values adding chance to loose 
synchronization but CPU load may be smaller.

Known issue: If reverb buffer is too large, Vortex 
driver will crash. This also happens with documented 
values, wich can be up to 1024 kilobytes.

2.1.3 Reverb on all channels

	If this setting is on, reverb will be added 
to all 3D streams. Turning off this setting may help 
if you want to free your CPU from work.


2.2 S/PDIF

2.2.1 Enable digital out

	If you don't need the digital sound S/PDIF 
output, than turn this setting off.

2.2.2 Enable AC3 pass thru
	
	It must be enabled for use your Vortex with 
external Dolby Digital decoders in DVD movies. If you do 
not use any digital out, disable this option.


2.3 AC97 Codec

2.3.1 Disable codec 3D effect by drivers

	Drivers turns off codec's internal 3d extension. 
This extension must NOT be used while A3D is playing. 
There is AC97 Mixer to use codec's 3D effect.
