Cheers Sérgio Silva for this one. RivaTuner is the most powerful tweaking utility for NVIDIA display adapters running under Windows 98 / Windows 98 SE / Windows ME / Windows 2000 / Windows XP. The purpose of this utility is to give you access to the many undocumented features of Detonator drivers. All versions of Detonator drivers have a lot of undocumented registry entries. Some of them don’t affect anything, but there are some that are very useful. In general, they cannot give you big performance boost but they can improve image quality and solve some compatibility problems.

- Minor bugfixes:
- Fixed the bug introduced in RC5.1, which prevented RivaTuner from detecting default clock frequencies after an attempt to enable hardware overclocking via Reboot mode under Windows2000/XP.
- Fixed CoolBits registry entry reset issue. The previous versions of RivaTuner set this registry entry to 2 after enabling overclocking and caused Direct3D VSync settings to disappear from NVIDIA control panel. Now RivaTuner changes the state of the second CoolBits bit only.
- Fixed the bug in the launcher item editor, which allowed in some cases a user to associate a preset, color scheme or display mode with separator items.
- Fixed SoftQuadro scripts for Quadro DDC. The previous versions of
these scripts forced wrong capability codes and blocked 3D textures
hardware support and some other capabilities.
- Fixed VSync prerender limit settings for the Detonator 3.xx

- What's new:
- Added Lightspeed Memory Architecture related options for GeForce3 based boards.
- Disabled texel alignment controls for GeForce3 boards on the Detonator IV and higher.
- Improved I/O driver (RivaTuner.sys) unlocks only the PCI and VGA I/O ports now. New driver fully addresses the keyboard lock issue in fullscreen DOS applications under Windows XP.
- New low level overclocking monitor. New low level core uses memory mapped I/O instead of VGA I/O ports. This allows to monitor the clock frequencies on non-primary NVIDIA display adapters. The previous low level overlocking monitor could also cause the system to hang during an attempt to read clock frequencies after resuming from suspended mode. This issue is fully addressed now.
- Added reboot notification messages for some Direct3D options. Now RivaTuner shows reboot notification messages when a user changes Direct3D options, which require reboot (e.g. Direct3D texture format settings).
- Added built-in 60Hz refresh rate fix for Windows 2000/XP. This fix enumerates all the display modes supported by your graphics hardware and allows it to use only the maximum supported refresh rate for each display mode.
- Added low level driver independent overclocking module for NVIDIA based display adapters. Now RivaTuner can directly program NVIDIA core and memory PLLs and set the clock frequencies bypassing the driver. I've added this module special for GeForce2 MX owners to work around the major overclocking problems, introduced in the DetonatorXP.
- Added low level graphics subsystem diagnostic module. Now RivaTuner can save northbridge and display adapter related diagnostic information to the report file. Graphics susbsystem diagnostic module can also track changes in norrthbridge's and display adapter's PCI configuration spaces and even in graphics processor's registers.
- Added database builder scripts. Databases for the Detonator drivers are not included in the distributive now and generated via the database builder when you start RivaTuner in the first time. It allowed to crunch database related data in the distributive with 1:10 ratio.
- Extended preset format. Now presets can contain driver dependent and hardware dependent registry entries. It allowed to merge all the quality and perfromance presets for different drivers and hardware and crunch preset related data in the distributive with 1:10 ratio.
- Added databases for the Detonator 3.34 (w9x only), 3.56 (w9x only), 3.68 (w9x only), 3.72 (w9x only), 3.75 (w9x only), 3.76 (w9x only), 3.77 (w9x only), 4.20 (w9x only), 5.08, 5,1x, 6.1x, 6.26, 6.27, 6.3x, 21.83, 22.50 and 22.80.
- Improved FastWrites settings. Now RivaTuner can also override V_PEXTDEV_BOOT_0 strapping register, which allows the driver to use AGP FastWrites even if it is disabled in display adapter's BIOS.
