V.Control - 3dfx hardware tweaker

Win32 (Windows 95,98,Me,NT4,2000,XP) utility for controling 3dfx graphics adapters. Currently supports 3dfx Voodoo Banshee, Velocity, Voodoo3, Voodoo4, Voodoo5. Will enable custom refreshrates, overclock on the fly, restore desktop icon positions, and save registry tweaks as presets. Refreshrates and graphic processor speeds are controled by programing hardware directly. This utility will help fix Windows 2000,XP 60Hz issues with 3dfx GLIDE™, Direct3D, and OpenGL.

V.Control version 1.82 beta (376kb zipped)

Because V.Control accesses and controls hardware directly, you will be completely overriding the manufacturer default settings. After changing settings in OverDrive - HardwareOptimization, it is recommended to run extensive graphics benchmarking to check for any problems. Use with caution and at your own risk.

Note: Administrative privilege is required for installing and running V.Control under Win NT4,2000,XP
1. If you have previously installed V.Control, unload V.Control from system tray and then uninstall it.
2. Run setup.exe and follow instructions.

Q. How do you do stuff on the fly?
A. It is done by programming the hardware directly and not a registry thing. This way we have full advantage of our hardware.

Q. OverDrive is greyed out, what gives?
A. Your video graphics adapter is not supported.

Q. My PC freezes or shows garbage on screen after changing OverDrive settings.
A. You may be overclocking too much. Lower your clock settings. Or it may be due to other settings in OverDrive which your system cannot handle.

Q. 3dfx environment setting registry tweaks doesn't seem to have any effect.
A. registry tweaks are driver dependent. Use the latest drivers available.

Q. I've changed registry tweaks from V.Control, but 3dfx Tools doesn't say so.
A. 3dfx Tools recalls what itself has set the last time it was used and does not show current settings.

Q. Do I need to have V.Control always loaded in the system tray?
A. You will need to have V.Control loaded in the system tray if you intend to use auto apply features. Other than that, load V.Control once, apply settings, and then unload it.

Q. If I keep V.Control loaded in the system tray, will it degrade performance of my system?
A. Running V.Control is same as using a device driver for one of your peripherals, it will take a tiny part of your CPU power but not in a way that it will bring down the performance of your system. If you are concerned with the small memory loss and cpu flops, you can unload V.Control once you have done the changes. The changes will stay changed unless some other program changes it.

Q. How do I make my own custom refresh rates?
A. Open OverDrive and click Hardware Optimization tab. There you will find the section for Custom Refreshrates. Under this section, select the resolution which you would like to make custom refresh rates with the drop down combo box (e.g. 1024 x 768), then choose the refresh rate of your choice with the up-down scrolls (e.g. 78 Hz), and then press Apply. The selected resolution and refresh rate will be tested and requested for confirmation. Click OK if you wish to keep the setting. All your custom refresh rates will be listed under List of Custom Refreshrates. If you wish to use these refresh rates constantly, tick auto apply settings when V.Control is active.

Q. How can I run V.Control every time windows starts?
A. Open the About dialog and tick load V.Control at Windows startup.

Q. I can't install or run V.Control what's up?
A. Administrative privilege is required for installing and running V.Control under Windows NT4,2000,XP. This is a safety measure.
Note: If you have a hardware mpeg2 decoder card installed, Hollywood plus, Creative dxr3, V.Control will not load under Windows 2000,XP. As I do not have one of those cards, it is almost impossible to find a work around. Let's cross our fingers those mpeg cards will receive none-beta drivers soon.

Q. Do I need 3dfx tools installed for V.Control to work?
A. Nope. V.Control does not need 3dfx tools to work.

Q. I get shimmering screens from custom refresh rates.
A. Lower 1 or 2Hz and the shimmer will disappear.

Q. Give me desktop/overlay gamma controls or I'll kill you.
A. Sure sure, I'll do it when I have the timecc
