Error: Couldn't create atlas bitmap

Posted: Sun Feb 25, 2018 7:08 am

So I just updated to the latest experimental version of Factorio (0.16.x), then proceeded to update/delete various mods. Upon restarting the game with most mods enabled I get hit with:

"Error: Couldn't create atlas bitmap (size 512X416). Probably not enough video memory."

I've got a MSI 970 GTX (Which has 4GB of VRAM).

As for mods, I'm running the exact same mods as I was on the latest 0.15 version (Minus things that are no longer needed like Offscreen effects, Water Fix, etc. And Alien Biomes which was causing it to fail on startup due to the 255 tile limit).

Not sure why this is happening, any help is appreciated

Here you go, it was complaining that it was too long so I had to chuck it on PB:

EDIT: I should also say, I've updated both the Razer Synapse app, and my Nvidia drivers. Still getting the same problem.

It allocates 3937 MB of VRAM before it fails to allocate more. It's quite possible poor old DirectX9 can't handle more than 4 GB of textures. Which seems to be the case in in Win10 1703 but was maybe fixed in 1709 update?

Huh, did not know this was an issue. Would I have to update via Windows Update then? The last time I needed something from it was when Halo Wars 2 came out. But it took about 2 days of pounding my head against the keyboard to actually get the updates to install...

You can try to set --force-opengl in launch options in Factorio properties in Steam Library. Or set --graphics-quality=normal to use normal resolution sprites instead of high-res (this should have happened automatically though), or delete mods that add ton of graphics.

It might help if you enable texture compression with no mods and then try again. I'm not sure what is the impact on visual quality.

If GPU-Z is to be believed then I seen Factorio go over 4GB VRAM usage on directx and it did not crash - usage listed was around 4.5-4.6GB.

So enabling texture compression fixed it even with all my mods still loaded. In fact, it got rid of a strange light flickering that was happening, doubled my FPS (while zoomed out as far as possible, I honestly thought that happened for everyone xD), and keeps my FPS at 60 instead of dropping to 58 and back rapidly.

Are there any side effects from enabling it? I can't really tell without timing it but I feel like the loading times got a bit longer. But I can live with that.

Anyways, thank you very much for your help :)

Yeah, longer loading times is one of the downsides. It may also increase CPU load in rendering because it breaks sprite batchng a little bit. But it shouldn't produce any visible compression artifacts.
All times are UTC
