Set up GLSL in Wine for Artemis

bgstack15

Comments

Following up on How I run Artemis Spaceship Bridge Simulator on Devuan ceres, I wrote a script that will set the GLSL variable in wine. Basically, if Artemis Spaceship Bridge Simulator fails in Wine, the first thing to try is to disable GLSL (which I just learned is superseded, so I have to go test with that new key at some point). I used the Wine regedit utility to export my registry key to a file, artemis-disable-glsl.reg.

��Windows Registry Editor Version 5.00

[HKEY_CURRENT_USER\Software\Wine\Direct3D]
"UseGLSL"="disabled"

Obviously you can just copy this and modify it for the "enabled" value. And the main script.

# Title: Script that sets up GLSL in Wine for Artemis on Weaker Systems
# Purpose: Make it easy to toggle the registry setting
# History:
# Usage:
#    WINEPREFIX
#    GUESS=1  If set to any non-blank value, try to guess WINEPREFIX if WINEPREFIX is blank
#    ACTION=enable|disable  Enable or disable glsl. Normally underperforming systems need to disable glsl.
#    DEBUG
#    DRYRUN

Use environment variables to control the operation! So to disable glsl, run: ACTION=enable ./use-glsl.sh As usual with my scripts, you can also use DEBUG and DRYRUN.
