A few different configs with a PvP map and determined you could fit a certain numbers of players on before server FPS dropped and the game started to crash:

On the server side we tested with a variety of core numbers and found the game basically only uses 2 cores, on the clients it does use more than that. The game automatically selects to turn off HT when it starts but you can force it on again but its a bad idea. Thus CPUs that are 4C/4T with the highest clock speed possible (overclock it is possible, it helps quite a bit) are probably the best bang for the buck. Nowadays its less exciting but still a net detriment and is usually best left off. Back in the A2 days that was a big performance boost, the game would loose a lot of performance with HT on. But it really does need a fast CPU and preferably an overclocked CPU to run well.Īrma 3 chooses the number of CPUs it is using to mostly avoid HT. I really like the way Arma looks, its got a realistic lighting system that isn't over done or highly stylised. Arma is a prime example of why so many games aren't multithreaded, its intrinsically difficult and it might be impossible (mathematically provable) to use multithreading fully in many games. They are working on a course grained threading approach but it likely wont work past a relatively small number of cores (4-6 I guess). They haven't yet found a nice way to utilise those additional threads for the AI (which is our biggest concern) or players for the server. Arma has one of the most advanced simulation engines ever made and its extremely complicated. But this is a problem they have been working on for years and its not easy to fix.

Practically I don't think there is much point getting a 6 core for the game, the price/performance isn't worth it, but it is the fastest solution we know of (we run a heavily scripted highly modded version of the game, as I think do most Arma communities).īIS have actually published quite a lot of details so to why they have this poor multithread usage and what they intend to do about it. That 15% will almost certainly be eroded by the difference in architecture that Haswell has compared to IB-E, certainly much of the advantage will be gone. The average FPS is most of the time improved by around 15% and the minimum also. In multiplayer, in real games using all 6 cores is better than limiting the game to 4 cores. They have now fixed it again for release and its back to scaling a bit better and running a lot better than it did during the beta. However this is in a single player environment in the middle of beta when everyone in tier1 agreed they seemed to have broken the engine from the alpha to the beta. Here we can see a very slight advantage to the 6 cores but its really not worth talking about.
