Hessle Posted August 23, 2019 Posted August 23, 2019 Hello all, been experiencing a popup that states server is overloaded and plane behaviour is erratic, unsure why this is coming up as I presume it is CPU bound... as described by the below picture you can see I have plenty of room. Can anyone explain why I am experiencing this? Or is it simply horrific CPU utilization for the AI aircraft?
Hessle Posted August 23, 2019 Author Posted August 23, 2019 (edited) Please explain the Tick Rate, I do not understand how this cannot be HW related? Google let me down when looking for clarification. Edited text: Tick rate Tick rate is the frequency with which the server updates the game state. This is measured in Hertz. When a server has a tick rate of 64, it means that it is capable of sending packets to clients at most 64 times per second. These packets contain updates to the game state, including things like player and object locations. The length of a tick is just its duration in milliseconds. For example, 64 tick would be 15.6ms, 20 tick would be 50ms, 10 tick 100ms, etc. Ok, so its server packets... this seems like an odd limitation for servers in IL2, unless I am missing something it seems like something that could be changed.

LLv34_Temuri Posted August 23, 2019 Posted August 23, 2019 It's not "rate" it's "Tick delay". Tick delay is the time required for one processing cycle of the simulation. The maximum processing value must be less than or equal to 20 milliseconds (20ms). If the value is greater than 20ms, the simulation slow-down becomes noticeable. 1
Hessle Posted August 23, 2019 Author Posted August 23, 2019 Thankyou for the clarification, Tick Delay makes more sense. So the only way to fix it is by reducing aircraft numbers in the mission so the server has less work to do, lowering the tick delay as it has less to process second by second? Upgrading my HW is not going to change a damn thing? We should rename this sim to "IL2 Minor skirmishes" So much for having immersive simulations of large scale aerial battles using AI, the example mission only has 14 aircraft per side.

The higher single core performance CPU you have, the better it runs. Don't look at the hardware monitor, it won't consume all it can Edited August 23, 2019 by LLv34_Temuri 1
Hessle Posted August 23, 2019 Author Posted August 23, 2019 Ok, maybe time to go look at a serious CPU upgrade... Until that time I may have to demote a squad mate to Host, pretty sure we can test an i5 8th gen. Thanks for all the replies, most helpful.
[MoKaMbO]jrepas Posted August 24, 2019 Posted August 24, 2019 (edited) Hessle Dserver uses only one thread (dont need a 6-8th gen) and its only matter the CPU-s clock freq. Btw if its everything runs fine just dont worry about the message. Edited August 24, 2019 by -[HRAF]Arrow19
Hessle Posted August 24, 2019 Author Posted August 24, 2019 Thanks Arrow, I understand though this is probably the best cpu we have to test it on, we have i5 3770, my i7 4770 and another with an i5 8 series... We are limited atm by hosting within the game menus, are we likely to gain better performance by using Dserver?
Hessle Posted November 12, 2020 Author Posted November 12, 2020 Hey all, me again resurrecting this topic from the dead... Recently upgraded my system and still get the Server overload message, running an i9 9700k @4.7ghz Could this be connected to my network speed? as I have a rather limited 2 mb upload limit
Sketch Posted November 12, 2020 Posted November 12, 2020 Are you a client connecting to a server? Or the server host? If you're the client, then it's not your computer. The server is getting overloaded - probably through the mission's design that has to many entities. If you're the server, then I would check your mission file and adjust it for better performance.
Hessle Posted November 12, 2020 Author Posted November 12, 2020 Hey sketch, thanks for the reply I am indeed the server, will look more at the mission limits in the advanced section as already using less than optimal aircraft numbers 16 or 20 for allied and axis respectively. Maybe the ground units and aircraft numbers have gone up in the more recent PWCG versions? Will tweak and hopefully find the sweet spot. Cheers

coconut Posted November 13, 2020 Posted November 13, 2020 If @Hessle is using PWCG, then all planes will typically not be active at the same time. What plane density are you using? If you are at high, try going down to medium. In my experience, this can still give you action-packed missions.
Hessle Posted November 17, 2020 Author Posted November 17, 2020 Thanks coconut, yeah I am running everything at medium atm in the quick settings. The reason I ask about server overload being somehow connected to my slow internet speed is because on an overclocked 9700k @4.7 I wouldn't expect the sim to still be having trouble... Though after playing the other day we did realize that even on medium settings the mission had an insane amount of units kicking around, especially having flights pretty close to each other, at one point we could see 5-6 other flights in view distance.
dENI48 Posted May 21 Posted May 21 Hey Hessle, few years later but wanted to ask you how did you end up solving this? I have a very fast internet and even better computer and I am still getting the same message even with everything on low and only airplane count on medium.
