Setup
In most cases, Open1560 should run optimally straight away.
You do not need to install the XP patch, or use dgVoodoo.
However, there are certain things you may wish to change:
- If you have a laptop, ensure you are using the correct GPU.
- To enable anti-aliasing, use the
-msaa <LEVEL> argument (possible levels are 1, 2, 4 or 8). This may not be available on certain older/integrated GPUs.
- If you have low performance:
- Try using the
-legacygl argument.
- Consider disabling cloud shadows, the rear view mirror, or lowering the far clip distance.
- If using Wine:
- If the hardware renderer is slow, try enabling threaded OpenGL with the environment variable
mesa_glthread=true for Mesa, or __GL_THREADED_OPTIMIZATIONS=1 for Nvidia.
- If the software renderer is slow, try setting the environment variable
SDL_RENDER_DRIVER=opengl.
- If your cursor does not move properly, try
-mousemode 1 or -mousemode 2.
Common Issues
- The application was unable to start correctly (0xc0000022)
Command Line Arguments
Open1560 uses command line arguments to configure certain aspects of the game.
These can be passed on the command line, or in a file named commandline.txt.
