What graphics card do you have?

OP has a GTX 1050, which has 2GB of VRAM. I was talking with someone I know a couple days ago and he alleges that he's been seeing decreased performance between 2.1.9 and 2.1.11; he has a GTX 770 (also 2GB VRAM), so I'm wondering if it's something to do with ...

Since I've been having some framerate issues since 2.1, I went ahead and tested this on 2.0.77 and 2.1.11.
I found a very small difference between the versions, around 0.5 ms extra draw call time for 2.1.11, both versions just barely keeping up with 60 FPS.

I created a map with seed 123456 and ...

The most bizarre thing to me is that it's a 2.1-specific issue. I've never had framerate issues prior to 2.1. I would think texture arrays are a given with the amount of sprites this game has.


according to FFF worms got revamp on 2.1, could be an issue. on texture arrays - back in those days ...

Can confirm that performance on Vulcanus is great now on 2.1.10, although Gleba can still hitch a bit with rendering at times due to high draw call count for decoratives.

I've done even more testing today. I tried running the game on my laptop with both an AMD iGPU and Nvidia dGPU. Since it's Linux, AMD iGPU performs better than the Nvidia dGPU, nothing unusual there. There was maybe a small difference between X11 and Wayland so it's not only a Wayland issue.

The ...

I tried the same scenario again in 2.1.8 and the problem persists. The number of draw calls (if that's what's displayed in the first row of debug text in the screenshots) is still ~40x higher than in 2.0.77. Might be something really strange going on with SDL3 or some other library that interfaces ...

Thank you for looking into it, hopefully the fix is simple.

I've done some additional testing and it looks like the Windows version is running as expected so it seems to be a Linux-specific issue. Another user on Reddit seems to also have what appears to be the same issue on Linux when viewing Vulcanus's surface.

I did notice 200-300 MB higher VRAM usage but that alone shouldn't have noticeable impact. Could it be caused by SDL3 or some other middleware that cannot properly detect some hardware features?
From my own limited game dev experience my intuition would tell me that the decoratives somehow aren't ...

After downloading experimental release of version 2.1.7 for Linux directly from factorio.com and opening the editor to test new things I noticed a very large rendering performance regression compared to the latest stable version (2.0.77) caused by decoratives.

Steps to reproduce:
-Create a new ...

Thanks for the amazing work, the new features and QoL are great.

I have one small suggestion, the underground pipes can now be connected to the circuit network but underground belts still cannot. I would really appreciate the ability to connect underground belts to circuit networks, it would help a ...

It would be great to be able to see the actual full number of items/fluids (or signal value) without prefixing/rounding.

For example when hovering over a signal inside a constant or selector combinator (aritmetic and decider combinators already do that when hovering in the input and output signals ...

Typing quality names into the search field of inventory, vehicles and other containers doesn't show any results which seems inconsistent with searches in the Logistic network view as well as the Production statistics view. For example, if I type "epic" into the Logistic network view I will get a ...
