Issue: Failed to create display LWJGLException: Pixel format not accelerated.

Cause: Out-dated video adapter driver.

Solution: Please update to the newest graphic card driver from the chipset manufacturer. Stock drivers installed by MS Windows for example do not support OpenGL.

Issue: Uncaught exception thrown in Thread[LWJGL Render Tread,5,main]
RenderException: compile error in:ShaderSource[name=MatDefs/Shield.frag, defines, type=Fragment, language=GLSL100]

Cause: Out-dated video adapter driver.

Solution: Please update to the newest graphic card driver from the chipset manufacturer.

Issue: RenderException: non-power-of-2 framebuffer textures are not supported by video hardware.

Cause: "Older The R300 and R400-based cards (Radeon 9500+ and X500+) are incapable of generic NPOT usage. You can use NPOTs, but only if the texture has no mipmaps.NV30-based cards (GeForce FX of any kind) are incapable of NPOTs at all, despite implementing OpenGL 2.0 (which requires NPOT). It will do software rendering if you try to use it.All newer hardware can handle NPOTs of any kind perfectly."

Solution: None at the moment.

Issue: "Spacemen" can't be open because it is from an unidentified developer.

Cause: In alpha/beta stage the Mac version is not signed as per App Store requirements.

Solution: Workaround

Issue: Failed to create display LWJGLException: Failed to set display mode (-2).

Cause: The selected settings, screen resolution and refresh frequency, were not accepted by the LWJGL.

Solution: Please start the game with different settings, first change the frequency, then resolution and finally full-screen mode.

Issue: outofmemoryexception during run time. Either heap memory or direct memory.

Cause: Most probably encounter either if you have under 1G memory OR using Windows 10, the allocated memory is insufficient to run the game.

Solution: If your system memory is 1G or more you can add the following system variable: _JAVA_OPTIONS = -Xms256m -Xmx512m. For example on Windows 10 go to Start, type Advanced System Settings, click Environment Variables, new variable named _JAVA_OPTIONS with the value -Xms256m -Xmx512m. The maximum memory (xmx) can be increased based on your system memory, recommended half its size. For example if you have 4G memory you can use -Xms1g -Xmx2g.
