Changes for 2.7
- "CyberGraphX style" double/triple buffering using vport scrolling on a single
bitmap didn't work at all. This should be fixed now.
- reworked the complete vblank handler since it did not work as expected. OS3
style double buffering should work properly now and dbuf messages should be
send properly sync'ed with the frame rate.
- modified driver init code to fix some problems at startup
- interlace modes are now automatically filtered when loaded because
CVisionPPC does not support interlace resolutions
- (hopefully) fixed some scrolling bugs introduced in 2.6
- the driver now limits the cgxmode pixelclock maximum to 100mhz in 32bit mode
and to 145mhz in 24 bit packed pixel mode
Changes for 2.6
- fixed autoscroll bug in 16/24/32bit modes
- added tooltype BITMAPCACHE=(YES|NO) to enable/disable caching of
bitmaps. Defaults to YES.
- added support for caching of displayable friend bitmaps e.g. smart refresh
layer bitmaps. This should speed up refresh of obscured smart refresh layers.
Requires at least cgxsystem.library 41.20
- added tooltype PACKED24=(YES|NO) to enable packed pixel mode
for 24bit resolutions. This allows higher refresh rates and
requires less memory. As a drawback, some accelerated
graphics operations and cpu rendering slows down. The tooltype
defaults to NO.
Since the packed pixel 24bit mode uses different display IDs you have to
change your screen mode settings if you have used the default 24bit mode
before
- added support for 1280x1024x32bit resolution with 8mb cards
- added acceleration support for non visible bitmaps
- added support for accelerated pattern fills
- added support for accelerated solid mask fills
Changes for 2.5
- initial release
