Using shaders with FS-UAE on Ubuntu [Solved]

[DaveMB]

Hi, Finally made a full and final switch over to Ubuntu/Unity (WinUAE was the only thing keeping me on windows) and have a couple of questions for you (sorry if they have been asked/answered already).

1) How do i use a HQ2X shader? (it works fine on WinUAE but I can't figure out how to do it on Ubuntu, Assuming it's possible?

2) Are there any plans to add the auto resolution switch function from WinUAE?

Edit: added a second question.

Excellent, let's hope you can stay on Ubuntu

The following option enables a bundled HQ2X shader if you run the development series (1.3.x) of FS-UAE:

shader = hq2x

But because the shader assumes that pixels are non-doubled, you will get best results with:

shader = hq2x
low_resolution = 1
line_doubling = 0

No, it does not change resolution at all currently, and while I may implement a switch-to-resolution/refresh feature, I don't plan to do any kind of auto resolution switching. With modern LCDs, you get best scaling results by using the native resolution of the monitor and scale the graphics.

FS-UAE is designed to run at the native monitor resolution (of course, ideally at 50Hz if the monitor supports it), but currently, you must manually change to a 50Hz mode. It uses the current desktop resolution.

BTW: If you use nVIDIA, you may want to read this:

Also, please note that Unity (the compositing versions) have problems with OpenGL applications especially in windowed mode, and you will likely see only half the frame rate / stuttering graphics. If you use the following option:

video_sync = off

the problem will go away, but this will also introduce tearing.

The other solution is to run FS-UAE in fullscreen (*) -or use Unity 2D...
(*) Unity may also have some problems with OpenGL fullscreen graphics.

I actually switched to using the KDE desktop for this reason. While it too has problems with OpenGL applications in windowed mode (with vsync), compositing can be temporarily turned off with a shortcut key, and fullscreen mode is fully unredirected OpenGL and works very well.

shader = hq2x
low_resolution = 1
line_doubling = 0

did the trick, thanks

and thanks for the other info as-well
