Troubleshooting
---------------

####

Problem: After installing this driver, the Control panel applet I had
for my 3Dfx based card is gone.

Resolution: As noted earlier, such applets and extensions are removed.
Please download and install drivers from your card manufacturer.


####

Problem: How I change the refresh rate and Gamma?

Resolution: Use the 3Dfx Control Panel applet that is installed

To change settings manually from within the registry, go to
the following key:

	HKLM\Software\3Dfx Interactive\Voodoo Graphics

	WARNING: Using Registry editor incorrectly can cause unexpected
	results.  Only those comfortable with altering the registry 
	should make changes.

	Add the following Entries as DWORD Value types:

	Value Name      	Value Description
	----------		-----------------
	REFRESH_512x384		Refresh Rate for 512x384
	REFRESH_640x400		Refresh Rate for 640x400
	REFRESH_640x480		Refresh Rate for 640x480
	REFRESH_800x600		Refresh Rate for 800x600
	(Supported refresh rate decimal values: 60, 75, 85, 120)
