software OS4   software OS4 : NetSurf 2.9 - Fast CSS capable web browser
   posted by zerohero on 15-Apr-2012 10:17:35 (4453 reads)
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.

See for more information about NetSurf.

Wow! Thank you for this update. Very fast on my MicroA1.

Up until this time, I have been using the Static/graphics.library versions of this program, up to and including NetSurf 2.8.

Thanks for the hint about dragging entries in the hotlist to the active window.

Thanks. I ditched the static version after a poll showed only about two people were using it. You can re-activate graphics.library only mode but it's not recommended.

I'd agree with you, but then we'd both be wrong.

- There isn't a copy of Installer in the archive, so I don't know where you are getting that from.
- "Some elf thing" isn't an error message! Please be more specific.

True, but "ELF Library
Unable to resolve symbol
'lwc_intern_string'" is.
