Bugfixes

• Limit maximum texture size the game will try to use to 16384x16384 pixels.
• Fixed desync related to building of rail signals. (37853)
• Fixed multiplayer map download getting stuck at 100% when using some broken routers.(32646)

Use the automatic updater if you can (check experimental updates in other settings) or download full installation at http://www.factorio.com/download/experimental.

The network issue was fixed? What was the issue if you don't mind me asking

They explained it in a FFF.

Also the alien artifect sprite updated?

I got all excited for a moment when I saw the updater - 0.15? Na, just a fix. Highly appreciated nonetheless. Love the great support here!

Im waiting the 0.15, for a moment i dream

I noticed this too. It's interesting, that the graphics got an update, when by 0.15 the artifacts are going to be removed entirely. I appreciate the art update, nonetheless!

We might use them in some high tier items as we do in modules level 3, but not in the research. The idea behind it is, that you can scale and automate the production quite well, but not the alien science pack gain.

As far as we know (for now) artefact won't be gone in 0.15

I am curious about the technical fix for the UDP checksum problem. Was the fix as simple as adding an incrementing integer to each frame that's ignored on the receiving side?

How do you ensure that you don't lock up a packet on a vulnerable checksum?

If the packet is dropped somewhere because of its checksum it will be re-sent with different random data, yielding a different checksum and allowing the packet to pass. The re-send already happened, but it sent the same packet (used the same checksum) so the packet never went to the destination. They added a random byte and now the packet has a different checksum the second time and is allowed to pass. (At least that's what I got from reading the topic - please correct me if I'm wrong.)

100% correct.

I'm just curious, isn't GL_MAX_TEXTURE_SIZE supposed to solve the issue about knowing the maximum dimensions of a texture on the chosen GPU?

It does, and it is true we haven't had issue with this in OpenGL yet. The problem is in DirectX9. Read this: 40375
EDIT: Actually we have issues with OpenGL occasionally too. On some Mac computers it claims 16k texture is supported, but when the game tries to use it, OpenGL crashes the game.

Oh, I had no idea it even used DX, why use both? Well, I've asked enough, and it's a broad question, no need to answer that. =)

Well, we think DirectX is better on Windows (performance wise)
OpenGL is there for Linux and MacOSX builds, and also as option for troubleshooting Windows users.

Does this change the Quality?
And if so, will it be reverted if NVIDIA fixes the bug?

In all honesty, I've done alot of benchmarking for pixel/fragment throughput, and it always turns out opengl is the faster option for simplified drawing (old pipeline and default shaders) and very little to no difference when it comes to instanced drawing (with heavy shaders), until DX12/Vulkan that is. But if you see a real lowering in performance on Linux from using OpenGL compared to DX9 on Windows, it means it is of course worth implementing both no matter what other peoples benchmarks say.

I could discuss things like this all day long, haha!

It doesn't change quality. We don't know yet if it is going to be reverted yet.

I wonder where you need any bigger than 16k textures? Is this a megatexture thing going?

Edit: Alien artifact sprite had me surprised a second. You need to update your avatars

you also change one graphic for alien artefact :
No ?
