(GTU version 3.0.2 readme.txt)

Hi there!

This utility allows you make a lot of modifications to the registry settings of your Geforce videocard. All registry mods work. From version 2.0 on the GTU includes a working overclocking feature (all earlier versions didn't do that correctly).
There are some beta options that you can use, but I don't know if (and how) they work. Try them at your own risk.

Requirements:

Windows 95/98/SE/ME, Windows2000, WinXP
(Perhaps it works with WinNT 4.0)

A Geforce 256 / Geforce 256 DDR / Geforce2 GTS / Geforce2 MX
The Quadro / Quadro2 / Quadro2 MXR should work, too.

NVidia reference drivers: version 5.08 and later
ASUS drivers: the 5.16 or later drivers will work
ELSA drivers: the latest drivers are based on the 5.xx NVidia drivers, so they will work.
Some of the new options will only have an effect when you use the Detonator3 drivers.

Theoretically the prog works -because of the same drivers- with TNT / TNT2 too, but I made some "bad" experiences with a friends TNT. That's why the program will only run with a Geforce / Geforce 2.
If you think you need to run it on any other card you can do it the following way: After starting the GTU an error message will appear. Press "Ignorieren" to use the program.
But after all it's NOT RECOMMENDED to use the GTU on any other card than on a Geforce / Geforce 2. (I think the overclocking feature WILL NOT WORK on any card that is older than a Geforce)

Command line switches:
/F:x
When your "large font" is not detected correctly then you can enter a number (e.g. 120) that might help to make the GTU easier to handle

/fast
Settings will be optimized towards performance

/quality
Settings will be optimized towards quality

/old
The old video adapter detection method is used.
Try this option if the GTU doesn't detect your adapter.

/all
This will let the GTU use any NVidia videocard, not only GeForces

Additional note:
Move the mouse pointer over an option you want to change and you will get an information what happens after changing this option.

History:

version 3.0.2:

Optimized "Pre-GTU system state"-button 
Now the statusbar confirmes changes in w2k, too. 
bugfixes at: 
"S3TCQuality"-button (w9x) 
"Render no more frames ahead than"-button (w9x) 
New for OpenGL: "Enable fast linear-mipmap-linear filtering" (w9x) 
The GTU has better Stereo3D support: You can alter the values for StereoConvergence, StereoSeparation and SnapShotQuality.
(The 1st and the 2nd are the basic Stereo3D tweaks)

version 3.0.1:

Under w2k the S3TC quality option didn't work correctly. Fixed. 
I think the DynamicFSAA option had an error, too. I changed the value of the "Antialiasdynamicenable" entry to "4" instead of "1". (w2k & w9x) 
The "Anisotropic4tap" option under Beta -> D3D might help your performance / image quality! Read its help! (w9x) 
Changes at the D3D FSAA option: The 10.50 driver does only allow up to 2x2 FSAA under D3D. (w9x) 


version 3.0:
(Sorry to all Win2000 users... no updated features in this release (again...) but I'll promise the next GTU will have new features for Win2000!!)

- You can force the GTU to use older NVidia cards by starting it with the command line switch "/all". (This is something that works since GTU v. 2.6 but I forgot to mention it in the last release ...)
- Modified & renamed the "Antialias Dynamic FPS" option.
  This is a very interesting feature of the drivers: With this option you are able to define the minumum desired framerate when using FSAA. Example: You enter a value of "30". Now the driver decides which FSAA mode it uses, to achieve your 30 fps.
- If no Nvidia adapter can be found the GTU automatically tries to find one with the "/old"-option.
- The old help system has been replaced by a new one: Now you can find the hints for all the options in the statusbar
- The statusbar has a 2nd funtion: It confirmes the changes the user has done.
- In order to make the GTU enable the Stereo support in OpenGL I removed the auto-enable of the StereoConvergence option. Thanks to Toxic-X of Stereovision.net - he always keeps me updated with good information on the Stereo settings... :-)
- Under the Import/Export-tab the GTU shows form where you imported your settings
- some code optimisations
- The most wanted feature (as I have noticed) for the GTU has been implemented: At its 1st startup the GTU saves all current NVidia settings. To bring your system back to the pre-GTU state you need to press the "Pre-GTU system state"-button.
- New Options:
    BETA General:
      DisableTVOverscan, TwinViewDisabled, Nv11DVIConnectorOnly, TVOutOnPrimary, DisableTVClockInversion
    BETA OpenGL:
      TextureDirectLoad, DefaultLogAniso
    BETA Direct3D:
      ANTIALIASCONVOLUTIONFASTMODE, FORCEANISOTROPICLEVEL
    Stereo3D:
      CycleFrustumAdjust, NoOrthoStereo, LaserSightEnabled, LaserSightProperty
    General:
      Enable256Burst
  There would be some more options I could add, so stay tuned for the next version.
- bugfix at the color correction tab

version 2.6.1 (only bugfixes this time):
the "Zugriffsverletzung bei ... " bug is fixed - to apply this bugfix it might be necessary to press the "Rescan"-button (once)
bugfix at the "Advanced"-button under the "GTU settings" tab
some bugfixes at the color correction tab

version 2.6:
Bugfixes at the following options: Anisotropic4Tap, FavorSZ, AGPTexCutOff, FogTable emulation
added multi-adapter support (that means the GTU can control more than one Nvidia adapter in your pc)
improved adapter detection mechanism
new tab: "GTU settings" - this gives you more control over the GTU
You can enter the registry path to your video card manually - that means you can (theoretically) use the GTU with all vendor specific drivers now!
You can choose if you wish the GTU to use its driver specific interface
Because of some incompatibilities on some user pcs there's an option to prevent the GTU to auto create the beta entries
small registry bugfixes
GTU FAQ update

version 2.5.1:
some modifications at the version detection mechanism (w98) 
Removed some old, unnecessary options (w98) 
fixed Detonator 6.xx/7.xx D3D Vsync problem (w98) 
the "default values"-button has been made more easiely to handle (w98) 
The GTU now knows the default values of ALL entries (w98) 

version 2.5:
Another problem of the GTU has been solved: The GTU is now able to detect the driver version. This results in a version-specific behaviour of the program.
FSAA changing did not work with the 7.xx Detonator drivers. Now it does.
Small bugfix at the color correction tab.

version 2.4:
New Beta option: "VS_HOS_EMULATION" (w9x)
changed the value of "NV15Alines" form 1 to 2. Now this entry works correctly: it boosts OGL wireframe performance in tests like "SPEC ViewPERF" (w9x)
disabled overclocking with ASUS / ELSA drivers (because it doesn't work with the GTU) (w9x)
The "Enable Fogtable emulation" has been renamed to "Disable Fogtable emulation" (The function did do the opposite of what it should: "Enable" disabled FTEmu and the other way round) (w9x)

version 2.3:
Fixed bug that could make the GTU display wrong settings (w2k)
Added color correction support (w98)
Some layout improvements :-)
Changed the copyright status of the GTU (read the information box in the "information" tab of the GTU)
Moved "DXVAEnable" from the beta options to D3D. I think it's to enable "DirectX Video Acceleration" (w98)
17 new options for Windows 2000. Examples:
Direct3D
- DirectX Video Acceleration
- W-Buffer settings
- Z-Buffer compression
OpenGL
- Force 16bit Z-Buffer
- S3TC quality bugfix
Added a beta settings tab in the W2K version!
4 New entries in the beta tab (w98) - one is: "UseIntelCompat"
Added "Laser Sight" option to the Stereo3D tab (That's what I thought when I found the entry: "ASUS 3D See Through" ... But I guess I'm wrong.)
4 new options in the "General" tab:
- Enable AGP Fastwrites
- Disable AGP Fastwrites Disconnect
- Enable AGP SideBandAdressing
- Enable AGP Fastwrites Strap
The program disclaimer has changed.
(Webmasters: You are no longer allowed to distribute the GTU. But you may place a link to guru3d.com/geforcetweakutility.)

version 2.2:
Added support for a new bundle of features of the 7.xx Detonator drivers:
The new drivers have stereo capabilities!
(That is what I think of this feature: This either is for multi-monitoring or the support of stereo glasses, such as the ELSA 3D Revelator.)
Moved the W-Buffer settings from the Beta options to the Direct3D tab
Added "Z-Buffer Compression"
Some new beta options (e.g. "NV20Emulate" - The 7.xx drivers already support the NV20!!)

-- Some words on the "NV20Emulate"-option:
If you want to see an interesting effect, check the NV20Emulate box. Then start Quake3Arena and go to the "Setup" menu -> "System" -> "Driver information"
There you see the name of the chip --- I can read 'BoomBoom/emulated ... '
I think BoomBoom might be the name of the next chip (NV20) released by Nvidia!! But it's only an assumption of me.

version 2.1:
When you use the large fonts on your pc then you'll like this update: All components are completely visible now! 

version 2.0:
That damn overclocing feature is WORKING now!! (w9x)
This is a result of a good work together with Andrew Charnley (NVMax) and Alex (RivaTuner). 
fixed a bug that appeared when you minimized the GTU twice. 
fixed DirectX antialiasing problem in W2k 
fixed small bug of the "fast settings" and "quality settings" button (w2k) 

version 1.1:
changed the behavior of the "fast settings"-button
(Thanks to Valtteri Ernen) and the hints of some options (W9x)
added "Set IoPageLockLimit to 0"-option (W2k)
added "Largepage minimum = -1"-option (W2k) --> That's the fix AMD and Micro$oft released for those who've problems with their Athlon and Win2000.
changed my email-adress in the help menus
added feature to save/load your personal settings (W9x / w2k)
added feature to send the GTU down to the system tray as a tray icon (W9x / W2k) ... tnx to MiGa!!
Note: When you minimize the GTU it will become a tray icon!!
removed stupid bug of 3 D3D (W2k) options: "Mipmap Detail", "Mipmap Level" and "Render no more frames..." were linked together.
the four buttons "fast settings", "quality settings", "default settings" and "undo changes" now are available in W2k, too.

version 1.0 final:
I got some info on the "MaxNVAccel"-beta option, renamed it and placed it in the OpenGL options. (W9x) 
Removed a bug in the "Undo changes" button (W9x) 
New options:
"Enable fast copy pixels" (W2k & W9x)
"Enable hardware tweaking menu" (W2k)
"Enable dynamic Antialiasing" (W9x)
"Antialias dynamic FPS" (W9x)
29 new, interesting beta options! (W9x) 
The GTU works with Windows ME! (again)

version 1.0.12:
The GTU works with W2K now!
(But the W2K support is only in a testing phase at the moment, there could be bugs.) 
added OpenGL "FSAA Quality" option 
added "enable Fastwrites" option 
lots of code optimisations, removed some small bugs 
changed the layout 
added "AGP Transfer Rate" option 
added OpenGL "Texture precache" option 
removed second "Buffer flipping mode" option 
added "Do I/O to flush cache" option 
changed the GeForce detection method - now it should work with digital TFT displays, too. (By starting the GTU with the command line parameter "/old" you can use the old detection method, if the new doesn't work with your drivers) - I hope this won't result in more bugs... 
Now it's possible to use the program with TNT / TNT2 based display adapters.
(After starting the GTU an error message will appear when you have a non-GF/GF2 . Press "Ignorieren" to use the program.
But after all it's NOT RECOMMENDED to use the GTU on any other card than on a GF256/GF2GTS/GF2MX.) 
The command line switch "/fast" activates fast D3D and OpenGl settings.
The command line switch "/quality" activates the best D3D and OpenGL quality settings.
These settings can also be activated by pressing the "fast settings" or "quality settings" button in the GTU. 
GeforceTweak now is compatible with the latest ELSA drivers! 
There's an "undo changes"-button now. The GTU remembers the settings it found when it was started and restores them when you press the button. 
The new "standart settings"-button removes all changes that were made by the GTU. 
Added "Use unified back/depth buffer"-option 
There are 2 new beta options available 

version 0.71:
fixed broken link to the latest Detonator drivers 
fixed small registry bug (see this page for more infos) 

version 0.7:
fixed a BIG bug, that made Geforcetweak sometimes stop working after installing new drivers 
All ASUS drivers (based on the 5.xx Detonator drivers) should work - not only the 5.16 drivers. 
if you use ASUS drivers: diabled options that don't work with these drivers 
added "buffer flipping mode" option 
changed some textfields 

version 0.6:
Now it works with the latest ASUS drivers (these are based on detonator 5.16), too! So you can use your ASUS stereo glasses AND tweak the drivers with my prog!
(thanks Francis!) 
added "Disable DirectX6 features" for more compatibilty 
fixed "Konnte Daten fr '...' nicht setzen"-bug 
added "enable anisotropic filtering" option 
Core/memclock settings are useable! But I don't know if they really work. (Please report your experiences!)
Try them with care - you need to know what you're doing! You can seriously damage your card if you set wrong values! 
changed the reg-key for the Beta-checkboxes 

version 0.52:
added option to download Detonator drivers ver. 5.30 
added link to this page 

version 0.51:
some minor bugfixes at the beta options 

version 0.5:
added beta options 
disabled (again) Core/Memclock settings... it simply didn't work 
all the checkboxes should now provide help if you move the mouse pointer over them (..not all of them are useful...) 

version 0.4:
first test of Mem/Coreclock 
added feature to find the correct Geforce registry key (if you have more than one Geforce, the tool will use the first it finds in the registry!) 

version 0.3:
first public release 
all registry mods seem to work as they should 

Future plans:
I'll try to support all the vendor specific drivers - if they are based on the NVIDIA 5.xx (or better) ones. 
The user shall have the possibility to change the refresh rates of any available resulution 

Problems:
I only own an Elsa Erazor X - anyone who wants to support me with a Geforce 256 DDR, and/or a Geforce 2 GTS? I need them to finish the core/mem clock settings. But not only for that ;-)
