Hi folks.

Don't know why it isn't supported as there are a lot of Mac users with an Intel HD graphics card.

We do support the Intel cards that are powerful enough, like the Intel Iris Pro. Intel make integrated cards and most of them don’t offer the performance a dedicated graphics card from Nvidia or AMD will provide, which is why the list of Intel cards supported for gaming is limited.

As expected, those warmongering Linux troops thrashed us at Company of Heroes 2 yesterday! But we had a great time, and we'll run more multiplayer events in future on both Linux and Mac.

Do you have any suggestions for BeatFeral sessions, such as commentary, timing, or streaming on Twitch as well as YouTube? Our multiplayer ambitions are all about you, so you’re on our war council.

Realy? Why other games in CS:GO, Dont Starve, Left 4 dead and etc. have a cross-platform game, but you do not have?

Hi John. We've released many games that support cross-platform play, like the F1 series, DiRT 3 and XCOM: Enemy Unknown.

However, not all games are designed the same. For instance, XCOM: Enemy Unknown is not designed the same as Company of Heroes 2. We always support cross-platform play when possible, but in some cases it simply isn't. We appreciate that people want to know why it wasn't technically possible in this case, which is why we wrote the explanation in the original post.

Would it be possible to release a 'beta' version with the cross multiplayer work so far. I would be up for testing it even if it fails more often than not.

If any such version becomes available, we'll let you know, but do please remember that it's unlikely.

Can be at least Mac vs Linux ?

Unlikely. We tried. :)

It seems like if this is a consistent problem that some kind of math library that matches Windows results could be helpful across all titles. I don't want to just see Wine "ports" but could their libraries be helpful here?

I'm afraid that's not useful when developing a native application, but thanks for the suggestion.

Thanks everyone for your understanding. See, this is why we always try hard for you lot!

And the short explanation above sounds somehow like one build is using compiler dependent fast math instead of IEEE fp computations. If this is the case, would it mean that the biggest problems could be solved by Relic by rebuilding the Windows build with standard fp and patching existing Windows installations?

So this is basically a problem with mathematics? Aren't there cross platform libraries available which ensure that calculations are the same regardless of platform?

Thanks for your thoughts, both, but there's no single change that would fix the majority of potential issues. It’s a combination of many things. Rest assured we've looked into this from many angles before making the decision we did.

Yep, I do! Mine is for what I deem to be under-the-radar games with Linux support.

Great idea!

Edit: Mac vs Linux cross-platform multiplayer is now supported in Company of Heroes 2 and its expansions.

It wasn't possible to support cross-platform play for Company of Heroes 2 for a number of reasons; and each of those reasons is itself multifaceted. Some have asked for a technical explanation, so brace yourself for a flavour of the challenges that cross-platform multiplayer support can bring.

Company of Heroes 2 uses a deterministic engine, and relies on clients to generate the same outcome for all gameplay-relevant calculations, like pathfinding, unit positions, spawns and combat.

Any differences in the maths, even at the nth decimal place of precision, will accumulate to a tangible divergence in behaviour and ultimately a disconnect. When dealing with multiple architectures, operating systems and optimising compilers, tracking down all possible differences is a long and complex task.

During development, cross-platform multiplayer was absolutely one of our goals and we invested countless man-hours in isolating and resolving these subtle differences. And although we made progress on some of these issues during development, it's impossible to know how many issues remain and how much more work would be required on ALL platforms to get the title communicating successfully across Mac, Linux and Windows.

Given all this, we took the decision to release the title with per platform multiplayer and keep investigating to see if multiplayer will be possible via a post-release patch. But because of the complexity and the various unknowns, we believe this is unlikely.

As anyone who knows our work is aware, we have a good track record of going the extra mile (or three) to add polish and functionality to our releases. However, in this case the quantum of work versus the low likelihood of ultimate success means that that we have had to compromise.

That's why we want to encourage Mac and Linux gamers to join this Steam Group, which should make finding participants for CoH2 Mac v Mac and Linux v Linux sessions easier.

There’s bloodthirst in the air. So if you’re on Mac or Linux and in possession of Empire: Total War on Steam, reply here and let us know what date and time you’d be up for a big multiplayer session. Don’t forget to mention your time zone.

We were thinking this Friday or some time next week.

Hi Konkeeee. Total War: ATTILA is by Creative Assembly; get in touch with them and I'm sure they'll help you out.
