Rivatuner 2.03 disponibile per il download
E' stata rilasciata una versione aggiornata di RivaTuner, popolare e completa utility con la quale analizzare le caratteristiche e il funzionamento della propria scheda video. Tra le funzionalità più utilizzate di questo prodotto citiamo i tool di overclock, sia di GPU che di memoria video, e il pannello di hardware monitoring, con il quale poter controllare dinamicamente e in tempo reale le temperature di funzionamento della propria scheda video, ovviamente a patto che su questa siano installati sensori di monitoraggio.
Il download è disponibile dalla sezione software di Hardware Upgrade a questo indirizzo. A seguire le note fornite a corredo:
- Fixed gamma correct antialiasing option for the ForceWare 1xx.xx drivers families.
- Fixed 'HDD0 temperature' ... 'HDDn temperature' graph labels in SMART.dll plugin for the systems with more than one hard drive installed.
- Minor UI and localization fixes.
- Updated databases for Detonator and ForceWare drivers. Added databases for ForceWare 162.18, 162.22, 162.50, 163.16 and 163.44.
- Added Catalyst 7.7 and 7.8 drivers detection.
- Updated Catalyst 7.7 and 7.8 certified SoftR9x00 parch script (for Windows 2000/XP drivers only).
- Updated RivaTunerStatisticsServer v2.4.0 bundled utility:
- Added OSD rendering support for Direct3D10 applications.
- Added OSD rendering support for Direct3D9 applications redefining render target in the end of frame rendering process (e.g. Overlord). Now the server is able to detect such conditions, bind render target to back buffer, render OSD then restore the previously set render target. This feature is implemented as compatibility flag and enabled by default for all applications, however power users may disable it via editing profile flags in the server's configuration file.
- Improved 3D API usage detection for applications using multiple OpenGL / Direct3D renderers (e.g. Colin McRae : DIRT). Now the server stores information about the last used renderer instead of the first one.
- Updated list of pseudo 3D applications.
- Updated D3DOverrider v1.4 bundled utility:
- Internal hook infrastructure has been seriously changed to provide support for Vista and future operating systems.
- Added experimental triple buffering forcing support for Direct3D10 applications.
- Added RivaTuner's event history panel support. Now besides sound indication of triple buffering forcing success/failure events D3DOverrider is also able to display triple buffering forcing related event markers in RivaTuner's event history panel. This feature is implemented as compatibility flag and enabled by default for all applications, however power users may disable it via editing profile flags in the configuration file.
- Improved hardware monitoring module:
- Added generic support for Logitech G15 keyboard LCD display. Now RivaTuner automatically maps all hardware monitoring statistics displayed in the server's On-Screen Display to the keyboard's LCD display, however power users may disable this behavior with MapOSDToLCD registry entry. Also RivaTuner provides command line switches for connecting to (LCDC/LCDCONNECT) or disconnecting from (LCDD/LCDDISCONNECT) G15 LCD, allowing you to bind these actions with hotkeys and easily reconnect to LCD (e.g. after resuming PC from suspended mode). Please take a note that these command line switches are added to the list of predefined applications available in regular launch item editor.
- Improved hardware monitoring plugins:
- Improved LCDHype plugin. Now the plugin contains LCDHype output scripts calibrated for both AlphaCool 240x128 and Logitech G15 160x43 LCD displays.
- Improved VidMem.dll plugin. Now the plugin totally hides videomemory usage graphs under Vista to avoid confusing the beginners ignoring plugin description, telling that videomemory usage monitoring is not available under this OS due to videomemory virtualization.
- Added protective technologies aimed to jam unsafe memory scanner of PunkBuster anticheat system and this way prevent
this anticheat system from crashing graphics hardware when RivaTuner resides in memory.
Unfortunately new 1.7xx versions of PunkBuster client (debuted on 04.17.2007 with
Battlefield 2142 client) caused major system stability issues in conjunction with wide
range of applications accessing hardware via user mode MMIO address ranges. Apart from
scanning executable code new PunkBuster services also fully scan data memory ranges of
each process, which is critically dangerous when it comes to applications accessing
hardware registers via memory mapped I/O port user address ranges. Unauthorized access to
hardware mapped memory ranges performed by anticheat system's memory scanner may cause
unpredictable results including hardware failures and freezing. The problem is not
specific to RivaTuner and also covers wide range of ATI and NVIDIA oriented diagnostic,
overclocking and monitoring tools (e.g. ATITool, PowerStrip, HIS iTurbo etc) developed by
third parties as well as by certified AIB/AIC partners. The situation had been
investigated with help of Battlefield 2142 gamers community and is fully documented in
RivaTuner's support forums, however, many inexperienced gamers never visit forums or read
documentation and still wrongly interpret these crashes as instability of third party
tools including RivaTuner, hurting software reputation in different forums this
way. Unfortunately, the problem is still neither fixed nor documented by Evenbalance,
furthermore, the situation got critically worse in the end on June 2007 when Evenbalance
launched the same unsafe PunkBuster clients v1.7xx for America's Army, Call of duty, Call
of duty 2, Enemy territory: Quake Wars, F.E.A.R etc. Due to this sad reason I cannot
longer wait for response and fix from Evenbalance and risk RivaTuner software reputation
because of anticheat system issues. The following features are introduced and aimed to
prevent RivaTuner from being improperly accessed by PunkBuster or any similar memory
- Process protection. Now RivaTuner reduces its own access privileges after startup to prevent simple user mode memory scanners from accessing RivaTuner's process virtual memory. This protective technique is enabled by default, but it can be disabled by setting ProtectProcess registry entry to 0.
- MMIO protection. Now RivaTuner hides MMIO range into kernel mode address space instead of user mode address space to prevent any other user mode application form accessing hardware improperly. This protective technique requires each graphics hardware access operation to be transferred via RivaTuner's kernel-mode driver, so it increases CPU performance hit caused by RivaTuner's background processes (e.g. hardware monitoring) with approximate factor of 3x - 5x. This protective technique is also enabled by default, but it can be disabled by setting ProtectMMIO registry entry to 0.
- Paged MMIO access mode. Now RivaTuner is able to use paged access to MMIO range, mapping
only desired MMIO pages for access instead of mapping whole registers aperture. This mode
is only available when MMIO protection mode is disabled. Paged acces mode can be activated
by specifying power-of-two page size with MMIOPageSize registry entry.
Note: most of these protective techniques will be enabled by default until the problem is fixed in PunkBuster. I realize that the protective techniques will cause side effects such as increased CPU load even to those who never play PunkBuster protected multiplayer games, but unfortunately I see no other ways of protecting software reputation against inexperienced gamers spreading rumors about RivaTuner instability. It you don't play multiplayer PunkBuster protected games or if you're not affected by crashing caused by it then it is strongly recommended to disable all the protections mentioned above.
- Minor UI changes and improvements.
