Summary0005172: (Sometimes) Very high CPU usage
Description

Sometimes - I couldn't see a pattern so far - the CPU usage spikes to an average of around >95%, which means it often hits 100% and therefore produces serious performance issues/FPS drops. It makes the game pretty much unplayable in that state, thats why I consider it a major issue. Closing the game and restarting sometimes resolves the issue but not always.

And yes, I turned everything else off and monitored CPU and GPU to exclude the possibility that some other program causes the problem. Screenshot attached.

Usually, my CPU is around 75-80% while playing and doesn't hit 100% and therefore runs comparatively smooth, even on full 64 players maps. (I almost exclusively play on 64 players conquest maps, problem occurs regardless of player count)

Also, It seems that it happens an all maps.

System:
i5-4590
Nvidia GTX 1050 Ti
16 GB RAM

I play on medium settings, GPU is usually far below limit.

Hello again,

here are some new informations, today I discovered something interesting:

I was playing Lupkow Pass (Conquest, 64 players) and the high CPU usage occured. Causing serious stuttering and FPS drops.

I played a while and it stayed that way. I then left the server and rejoined THE SAME SERVER, and this time, CPU usage was far more "normal". I didn't restart the game, just left server and rejoined.

See the attached screenshots. Screenshot one shows that the CPU is very much at its limit. Screenshot two shows a far more relaxed CPU.

Again: Same Server, same map, same time, server was full both times. I played a while and these CPU usages are representative for about 15-30 minutes of gameplay each.

Very unlikely to be a pure bug per se, considering that CPU is below minimum requirements (although it can't be ruled out that some other factors might be involved; unlikely to be the only/main cause though)

Thanks for the response.
CPU is below minimum requirements? First I thought you made a mistake but indeed, i5 4590 is now below the minimum. But I am sure when I bought the game the CPU was fairly above the minimum requirements. Seems somewhen after the release it was adjusted by the developers instead of trying to improve the performance. I mean you find a lot of people with the same issue.
That at least gives me the convidence that there won't be more performance improvements.... And I can stop complaining. Since my CPU is below the minimum now....

AMD minimum is the FX6350 though... which would in almost any other game perform much worse than an Intel i5 4590. But I got it, it is because the only 4 cores and no hyperthreading. At least what people speculating in the forums.

Funny thing though... The game ran perfectly smooth on the same settings (medium) with the Intel i5 4590 and an 4 year old AMD R9 270X.
A few monthes ago the R9 270X broke and I had to replace it with a GTX 1050 Ti (which is supposed to perform almost the same as the 270X, or a bit better). I had to buy the GTX 1050 because due to mining no other graphic card was available at a reasonable price.

With the new graphic card it all went worse, stuttering like hell, CPU spikes, FPS drops. I had to try almost everything (vsync off/on, frame limiting, changes in pre-rendered frames, other vsync settings in nvidia control panel etc.) just to get the game to a playable state which is still worse than before, but playable. Except when the CPU usage thing occurs, which I also never had with the old graphic card.

So it is quite weird. Somehow the same CPU worked better as a team with the much older AMD graphic card than with the new GTX... And although the CPU is the same, it has now this CPU spike thing...

Nevertheless, more screenshots:

Map: both Volga River with 64 players. Same game session, no other programms involved, at least not obvious...

I have the same problem, sometimes the CPU usage is so high the game starts glitching out, mainly the control speed is different. Here's a video where I recorded more or less the problem:

My CPU is a FX8320, which is better than the minimal required by the game. It's set at medium graphic settings.
