This document is for creating the 4.0 release notes. There are 3 parts:
|
|
- the notes themselves
|
|
- comments and todo's about what should be added to them
|
|
- comments about what should be in the accompanying kwin 4.0 video

4.0 release notes
|
|
=================
|
|
|
|
|
|
- Performance/smoothness with nVidia cards: Smoothness of KWin rendering
|
|
can be improved by setting env.variable KWIN_NVIDIA_HACK to 1 (e.g. append
|
|
"export KWIN_NVIDIA_HACK=1" to your ~/.profile file). This sets __GL_YIELD=NOTHING
|
|
for KWin, letting KWin use more CPU time for OpenGL operations, however
|
|
at the expense of affecting performance of other applications. This is
|
|
therefore disabled by default. This setting may be removed in the future
|
|
if the negative impact becomes insignificant. See section "OPENGL YIELD BEHAVIOR"
|
|
in README.txt for nVidia cards.
|
|
|
|
- XRender mode: It is possible to use XRender for compositing instead of the default OpenGL.
|
|
XRender mode in general has less features, however at the moment it is also considered
|
|
unstable - it has not received as much testing as OpenGL mode, some features may be incomplete
|
|
and it is recommended to use the OpenGL mode if possible. Also note that current XRender
|
|
implementations often perform rather poorly.

========
|
|
|
|
- mention how to turn it on
|
|
- refer to COMPOSITE_HOWTO?
|
|
- mention API is unstable, work in progress and whatnot
|
|
- hmm, better mention compositing as a whole is still somewhat experimental :)
