more or less recent information here, we are still waiting
Hello, to say it clearly. Factorio 2.0 is more demanding on GPU than 1.1 was, and Space Age significantly so.posila wrote: Tue Oct 22, 2024 10:49 am Dropping bellow 60 FPS, or stuttering sucks
For macOS players, I recommend to disable "Render in native resolution" in graphics settings, if you run into FPS issues.
Space Age has lot more complicated rendering to compose all the sprites and shader effects in somewhat acceptable way. We are always trying to find good compromises between visual fidelity and performance costs.
Thanks! We are looking forward to it!posila wrote: Thu Nov 07, 2024 2:12 pm Hello, to say it clearly. Factorio 2.0 is more demanding on GPU than 1.1 was, and Space Age significantly so.
If you could play 1.1 on high resolution display with "Render in native resolution" graphics option enabled and 60 FPS, your might not keep 60 FPS on highest graphics settings in Space Age, and possibly even in base 2.0.
To improve the framerate, at the moment you can:
Our plan is:
- Disable "Render in native resolution" (and restart the game)
- Disable individual effects like Show clouds, Show fog, Animated water, ...
- Implement Resolution scaling option, so that the game can be rendered in lower resolution (for example 70% scale) but GUI can be rendered in native resolution.
- Explore optimizations that would utilize high power of Apple Silicon CPUs to lessen workload put on its GPU.
Does that theory really make sense given the data in this thread? It seems to be related to the usage of external monitors. I'm surprised the team hasn't been able to get a repro of this issue with an Apple silicon mac plugged into an external monitor. Not to be too alarmist but I think this is close to "request a refund" territory, except the fact that 1.1 performance was great and we have faith the team is going to fix the issue. I understand MacOS users aren't a majority of the player base but I think this is pretty widespread and impactful, hope it gets the priority it deserves.posila wrote: Thu Nov 07, 2024 2:12 pmHello, to say it clearly.

Right, it does appear there is also some issue related to external monitors. Some of the posters here say they have 4K monitors, for them I believe my previous post applies. When I test it with USB-C to HDMI cable and 1920x1200 monitor, the game runs smoothly on the monitor in 1920x1200. And it also runs smoothly in 1650x1050 on the internal screen when external monitor is plugged in. When I did this, I saw some JPEG-like compression artifacts on mac desktop and also in the game, on the external LCD. I don't know how video over USB-C works, but it seems to me like some compression is happening, and perhaps GPU does the compression as opposed some dedicated chip, which would mean more load on the GPU? Also just having second screen, and OS having to compose image for that screen adds load to the GPU too.collinvandyck wrote: Thu Nov 07, 2024 2:45 pm In the interest of being clear, I also just want to reiterate that these jolts from 60fps to 30s and in between do not happen under load. These are on new maps, when nothing much is going on. I'm not arguing that what you are saying is wrong, but I also want to say that as a software developer myself, this feels like a hitch that is not entirely load related, but rather some other kind of contention in the pipeline in the circumstance where an external monitor is attached.
Right, the 2.0 is more demanding then 1.1, Space Age is more demanding than vanilla 2.0. The higher the resolution and the weaker the GPU, more likely it is you'll run into performance issues.

That's interesting, I have a theory that OpenGL or OS evicts our framebuffers or important textures from VRAM to RAM, making writing to framebuffers much slower. When you resize window, framebuffers get reallocated to match the new window size and now that they are smaller, they get allocated in VRAM again (or the evicted texture is made resident again)omcnoe wrote: Fri Nov 08, 2024 11:08 am I used the Activity Monitor "GPU History" and when FPS tanks, the GPU usage also drops down very low. Not sure what this means. And CPU usage will also be low.
Also, I noticed that sometimes slightly downsizing the window can suddenly get the game back to 60 FPS. Game will be struggling at <10FPS, slightly shrink the window down (not by a significant amount, <20% size difference) and it springs back up to 60. Feels a lot more like a bug than a lack of GPU performance, performance just hits a cliff in some scenes and dies.
After playing for three weeks, I noticed that fps drops after 1 minute (as if some buffer or GUI memory should be filled). any change in resolution after the FPS starts to decrease, or a change in graphics settings seems to reset this, and you have another 50-60 seconds before the drawdown begins (as if memory or some buffer will overflow again), the effect is most easily visible when changing the monitor resolution. everyone writes about similar effects in one form or another.posila wrote: Fri Nov 08, 2024 1:53 pmRight, the 2.0 is more demanding then 1.1, Space Age is more demanding than vanilla 2.0.

Either way, resolution scaling option should help in this case too.
