A27: Very poor performance on weak hardware?

[Seleucids]

Could we perhaps monitor the time taken to handle each task (e.g. how long it takes to execute a particular C++ function) to find the source of lag?

Another idea is async the GUI from the backend engine. Let the GUI run smoothly with animations but without attaching them to the simulation update loop of the backend.

You can look at profiler2 see https://gitea.wildfiregames.com/0ad/0ad/wiki/Profiler2

But most importantly we need to compare with A26 or at least maybe the first RC before the release was cancelled last year.

Thanks for the guide. My main question is: how can I re-compile the current release version of A27, as well as the released A26? 

I'm on Linux, so I assume I would have to download the source_code.zip right?

Yeah that's correct. Although if your repos still have it you might install it from there

I don't feel any difference personally but many people complain about it

amd ryzen 3600 (it funny i remember i had a lot of weird bug in 2020 but the kind staff 0AD fix it !)

I also didn't notice any changes in performance, although I thought we would see a significant improvement in this alpha.

Do you use GL or Vulkan?

Both, it made no difference to me.

Usually vulkan should have more stable fps than GL. I guess the users which will see the biggest difference are mac users (up to x5 fps)

Could we schedule a "fast PC" TG for this weekend? I expect that those with really slow computers or adversely affected setups like @Meister are slowing turns for everyone, leading to many reports from players that otherwise have good performance. However, I have never really tried to verify this is the case.

If we get a 4v4 where everyone has ideally >20 fps (min) in combat demo huge (found in scenarios -> demo maps -> combat demo (huge)), we can make sure that this is really the cause.

I'd like to do it on Sunday, maybe when we did the a27 RC test, 18:00 UTC.

@MetaPhyZic @BreakfastBurrito_007 @Ginnungagap, and any others that have good performance in a27.

minimum requirements?, A27 has performance issues even if I use good enough PC that can play AOE4 without any stuttering at all.

@leopard if you can do combat demo huge with better than 20 fps at minimum, please join us.

I had up to 10 fps, but when it came to a 200 pop situation, it was more like 0.5 to 1 fps. I played with lowest graphic settings, which used to get me 20-40 fps on a26. I tried both OpenGL and Vulkan, no notable difference detected.
Any idea why it is so much slower now?

are your a26 numbers including autociv? The feature that turns off bodies is pretty impactful when big fights are happening.

I think 0AD is not using GPU that much, uses less than 50% every time,

but AOE4 always uses 95% of GPU, when I try to change window to something else everything is stuttering, i.e, every other apps will run slow while AOE4 is running (plus I had screen recorder on).

I think we should be more greedy in terms of resources.

this was openGL, Vulkan is Better than this.
