[posila][16.0][Win10] GL_OUT_OF_MEMORY (but actually isn't?)

[piderman]

How to reproduce:

- Have a baseline of about 1GB video memory used (Firefox, Spotify etc)
- Start game
- Video memory usage approaches 3GB
- This error appears

The error does not appear when baseline is around 600MB and total usage including game is around 2.6GB. And in that case I can start other programs to exceed 3GB of memory just fine.

I have a GTX980 with 4GB memory total so 3GB should be totally doable, still Factorio has this error. Drivers are 388.31 .

An observation (not sure how accurate): I am able to reproduce the message 100% and no matter what my baseline video memory, the error always seems to happen with one of the artillery wagon textures.

Try reducing max atlas size - it might be that it's trying to grab very big texture and due to memory fragmentation is unable to do so at given moment and dies with out of memory error.

[piderman]

Well yes it feels like it is trying to allocate over 1GB of video memory and then using only a few megabytes of it. I don't think it's due to memory fragmentation since it always happens above a certain memory usage and never below that limit (which is about 1.1GB below the max available video memory).

I wonder why it uses OpenGL on your machine. On mine, it still uses D3D

[piderman]

Hmm I'll have a look at the boot options later today. I have set it to OpenGL sometime in the past because of some graphical issues and never set it back.

Some other guy posted a question about SLI support (he had extreme performance drop while in SLI, compared to when he had it disabled). I'll try to find the post. I see you have a GTX 980 SLI, so ...

Ok this seems to have been fixed, I suspect together with viewtopic.php?t=54548 .

Does it work reliably now?
I can see it fails on the almost same file as in the thread you linked, but in that thread GDI+ refused to decompress PNG file with "Out of memory" error code; you got out of memory from OpenGL
