Topic: software OS4

NetSurf 2.9 is a small, fast, CSS capable web browser for
AmigaOS 4.1. It sports an OS4 native GUI and does not require AmiCygnix. The OS4 code is not related to NetSurf-68k, which in turn is not representative of the user interface of NetSurf on any other platform.

This is a pre-release, there may be minor changes before a final release of v2.9.

The redraw method has been changed to conserve graphics memory, and the default options are set so users with low amounts of graphics card memory can enjoy NetSurf. Consequently performance can be improved by doing one or both of the following:
(a) Toggling "Cache native versions" in the Rendering tab of NetSurf's configuration, to "All".
(b) Increasing the values of redraw_tile_size_x and redraw_tile_size_y in Resources/Options, or setting them to 0.
There are further suggestions in the "optimising for speed" section of, included in the distribution.
