NVIDIA GeForce/TNT tweak guide

Drivers

You can get the latest reference drivers for the TNT1/2 & GeForce here available for Windows 9x, NT & 2000. For drivers for specific cards please go to the respective manufacturers website. This guide is based on the 3.xx drivers from nVidia.

NOTE – Some of the tweaks below, especially registry ones, may or may not work/apply depending on which driver version you have installed.

Some cards may need to have their own manufacturers driver installed to work properly.

Trouble-shooting

For game specfic help & settings take a look at the Sin, Unreal & Unreal tournament tweaking guides.

If you experience any in-game lockups & your video card is overclocked, try lowering the clock speed 3 – 5 Mhz increments until they stop.

If you have a Super-7 motherboard (or any other for that matter) you may have experienced compatibility problems. To fix these you’ll want to download the latest drivers/BIOS updates for that motherboard, check Windrivers for links.

This next piece of advice is from the nvidia newsgroup, alt.comp.periphs.videocards.nvidia & may also improve stability with Super-7 motherboards.

Right click on My computer. Click on the Device Manager tab. Open System Devices & go to PCI Bus. Right click on it & select Properties. Go into the Settings tab & set the Device Enumeration to Use Hardware NOT Use BIOS.

Now click the IRQ Steering tab & uncheck Get IRQ table using ACPI BIOS. Click "Ok" Reboot for changes to take effect.

Open regedit & open this key [HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Class\Display\000x\NVIDIA]. Where x represents the key with the sub-key NVIDIA. In this NVIDIA folder create a new dword value entitled Super7Compat & give it a value of 1. If lockups persist, try change the value to 2.

The GeForce is one power hungry card. To improve system stability you’d want to either;

A.     To have at least a 250watt power supply, or

B.      Try increase the I/O voltage of the motherboard. This can usually be done via the BIOS. This will allow the GeForce to get the power that it needs to run properly.

You might know of a particular problem involving distorted sound because of the AGP card incorrectly using up all the bus. The nvidia drivers (at least the 3.53 up to 3.77 that I've used) do this. The way to stop this sound problem is with the following key:

Open this key [HKEY_LOCAL_MACHINE\Software\NVIDIA Corporation\Global\System] Add a New Binary value entitled Super7Compat. Give it a value of 00 00 00 00. Alternatively, you can download the file here.

You can find more troubleshooting tips in Christopher Hill’s excellent Geforce FAQ.
