can't reproduce with 1781, may be a config- or driver-specific issue. is this bisectable to any recent build? |

I've had a look the other day and the FBO initialization code looked almost the same as in maintenance (where /shadow flip works ok). I'll try to roll back in time and see if it happens to the older builds. |

Looks like the issue (don't laugh) is map dependent. /shadows works perfectly on astroturf_v2_3a.sd7 and doesn't work on AlienDesert.sd7 I'm checking with develop compiled at https://github.com/spring/spring/pull/458 Can you check if it's repeatable on your end? |

Disregard, the smaller sized shadow map can be created, but not the map of the original size (8192^2). On AlienDesert sometimes I happen to succeed with 7k, but then it fails too, so only 6k can be created reliably. Needless to say I have 3/4 of GPU memory free. |

This is what I see if I enable DebugGL: [f=0000490] Warning: [OPENGL_DEBUG] id=0 source=API type=ERROR severity=HIGH msg="Unknown internal debug message. The NVIDIA OpenGL driver has encountered an out of memory error. This application might behave inconsistently and fail. (pid=19912 spring.exe 32bit)" I also tried x64/win build and I don't observe any errors like above or the bug. Now the question is: Is it NVidia shenanigans w.r.t. win32 drivers or x64 hides some spring bug. Guess we will never know, but looks like win32-develop is unreliable. |

Ha, have a look at this message produced by 32-bits build: [f=0001868] Warning: [OPENGL_DEBUG] id=1285 source=API type=ERROR severity=HIGH msg="GL_OUT_OF_MEMORY error generated. Failed to allocate CPU address space mapping for texture (consider building 64-bit app)." |
|
Kloot (developer) 2019-06-04 00:00 |
It may be possible to free up some of the address space (which has been getting crowded), but I'd rather use this opportunity to drop 32-bit support for 105 altogether tbh. RFC from anyone who still cares. |

105.0 released: the maintenance branch is discontinued/obsolete. |
