Novità rispetto alle precedenti versioni: Added context sensitive help system. Added "Restore clock frequencies after suspended mode" option. Now RivaTuner can save core and memory clock frequencies before suspended mode and restore it when system resume. This virtually fixes drivers' bug and helps to avoid 100/83 underclocking problem. Added "Enable Accelerated Graphics Port" option for Detonator 1x.xx for Windows 2000. Improved AGP Sideband addressing and FastWrites settings safety. Now AGP Sideband addressing settings are also disabled by default and protected by LockDangerSettings registry entry. Read FAQ to find how to enable AGP Sideband addressing in RivaTuner. AGP Sideband and FastWrites settings are also disabled if motherboard doesn't support it or it is disabled in BIOS. Improved AGP transfer rate settings safety. Now RivaTuner doesn't allow to select AGP transfer rate, which is not supported by motherboard or display adapter. Now RivaTuner can either use exported functions from the NVIDIA control panel and tweaking library or use direct access to hardware via ExtEscape calls. By default it uses ExtEscape calls for Detonator 12.40 and higher and exported functions for the rest of the drivers to adjust the color scheme and query/set clock frequencies in realtime. It allows it to avoid nvcpl.dll usage. ExtEscape is much faster than exported function calls, but it has not been completely tested yet. You may force exported functions usage if color correction or overclocking doesn't work properly on your system. Use ExtEscapeColorControl and ExtEscapeClockControl registry entries to force ExtEscape or exported functions usage. Added advanced overclocking mode for power users. Now clock frequencies can be applied and saved without test via DisableClockTest registry entry. Changed default Direct3D mipmap LOD bias adjustment interval from [-2; +2] to [-3;+3]. As before, Direct3D mipmap LOD bias adjustment interval can be changed form [-2;+2] to [-15;+15] via LODBiasRange registry entry. Added databases for Detonator 14.10 (Window 9x only) and 14.20 (Windows 2000 only). Added presets for Detonator 14.xx. Updated all performance/quality presets. Chaned Direct3D prerender limit from 1 to 3 in all presets. Update "Restore defaults" and "Safe mode" presets for Detonator 1x.xx for Windows 2000, Added advanced Direct3D anisotropic filtering settings for GeForce3 for Detonator 12.00 and higher. Added gamma ramp graphs in desktop color scheme window.
