Version 2.6
Custom Display Modes page updated to Version .004. Changes include:
Modified design.
The addition of all resolutions, both Standard and Custom.
Support for a Right-Click menu for each resolution, which allows you to specify your preferred refresh rate for all the resolutions
you use, both custom and standard.
Currently the refresh rate specification is only supported under Win9x/ME. Win2k support coming as soon as we get it working.
See the Custom Display Modes Help page for more information.
New "DAL" tweaks section in the Rage3D Tweak tab adds the following tweaks:
GCOOPTION_SlowerEdge = The long known shimmer fix for certain Trinitron and Diamondtron tube monitors, which for the most part I
think is not needed by folks anymore, but some forum posts prompted me to include this with the other tweaks anyway.
GCORULE_RMXSupport = This setting Enables the "Scale image to panel size" button so that it will appear in the FPD (Flat Panel
Display) section of "ATI Displays" in the advanced display properties. This option will scale resolutions lower than the maximum
supported by a given flat-panel screen to be the full size of the screen instead being displayed in a smaller window. Changing this
setting requires a reboot. (note: this won't do anything for you if you don't have a Flat Panel Display).
**TVEnableOverscan = Added by user request, enabling this option should enable TV Overscan support for Radeon cards with the Rage
Theater chip. (This may also work for any ATI card using the Rage Theater chip) **
Updated installation program.
Updated Help files.
