Do you have any problems with the lag when playing with your friends multiplayer Sudden Strike???  This topic will suggest you what to do to play the best realistic strategy WW2 played without any problems.
Before I had problems with this, so I had to mute the sound in the game so I could play it, then i find a solution of my problem.

As always make a system restore point before making and registry settings, make a backup of your registry too. You don't have to, nothing should go wrong but it's always better to be safe than sorry.
It's crazy how much microsoft gimps your PC from it's full gaming potential and the amount of stuff they hide from you.

For Windows 7:

* Open regedit
* Go to: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Multimedia\SystemProfile
* There will be an entry for network performance throttling, default value is 10; set it to FFFFFFFF hex (willl look like 0xFFFFFFFF to the right of the entry)
* Reboot


-update another tweak In Windows 8/8.1, just like with Windows 7, multimedia applications use the "Multimedia Class Scheduler" service (MMCSS) to ensure priritized access to CPU resources, without denying CPU resources to lower-priority background applications. However, this also reserves 20% of CPU by default for background processes, your
multimedia streaming and some games can only utilize up to 80% of the CPU. This setting, in combination with the above "NetworkThrottlingIndex" can help some games and video streaming. We recommend reducing the reserved CPU for background processes from the default of 20%.

Navigate to:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Multimedia\SystemProfile SystemResponsiveness=10 (DWORD, default is 20 denoting 20% of CPU reserved, recommended: decimal 10, or 0 for pure gaming/multimedia performance)

Notes: The number in this key is rounded by MMCSS to the nearest 10. In some server operating systems (Windows 2008 Server), the SystemResponsiveness may be set to 100, instead of 20 by default. This is by design, giving higher priority to background services over multimedia.



For Windows 10: How to Tweak Windows 10 for Gaming

- Nagle’s algorithm combines several small packets into a single, larger packet for more efficient transmissions. This is designed to improve throughput efficiency of data transmission. Disabling “nagling” can help reduce latency/ping in some games. Nagle’s algorithm is enabled in Windows by default.

To implement this tweak, modify the following registry keys.
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces{NIC-id} For the {NIC-id}, look for the one with your IP address listed. Under this {NIC-id} key, create the following DWORD value:
TcpAckFrequency and set it to 1 to disable “nagling” for gaming.
TCPNoDelay and set it also to 1 to disable “nagling”
TcpDelAckTicks and set it to 0

Note: Some reports say that the tweaks did reduce latency when playing Dota 2 and League of Legends but it doesn’t work for some. I have tried it and my latency improved from 110 to 90ms (SEA Server) when playing Dota 2. Network Throttling Index


-Windows implements a network throttling mechanism, the idea behind such throttling is that processing of network packets can be a resource-intensive task. It is beneficial to turn off such throttling for achieving maximum throughput.

To implement this tweak, run regedit and modify the registry HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Multimedia\SystemProfile. Under SystemProfile, create a DWORD value and name it to “NetworkThrottlingIndex” then set its Hexadecimal value to ffffffff for gaming and max throughput: ffffffff completely disables throttling. System Gaming Responsiveness


-Multimedia streaming and some games that uses “Multimedia Class Scheduler” service (MMCSS) can only utilize up to 80% of the CPU. The “Multimedia Class Scheduler” service (MMCSS) ensures prioritized access to CPU resources, without denying CPU resources to lower-priority background applications.

To implement this tweak, run regedit and modify the registry key HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Multimedia\SystemProfile. From there, create a new DWORD and name it to “SystemResponsiveness” set its hexadecimal value to 00000000 for pure gaming/streaming.


-In the same Registry hive as the above tweak, you can also change the priority of Games. To implement this tweak, go to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Multimedia\SystemProfile\Tasks\Games and change the following registry values:
“GPU Priority” change its values to 8 for gaming.
“Priority” set to 6 for gaming.

-Disable Receive Segment Coalescing State (RSC)
This is applicable to Windows 8/10/2012 Server, not available for earlier Windows versions.
Receive Segment Coalescing (RSC) allows the NIC to coalesce multiple TCP/IP packets that arrive within a single interrupt into a single larger packet (up to 64KB) so that the network stack has to process fewer headers, resulting in 10% to 30% reduction in I/O overhead depending on the workload, thereby improving throughput. Receive Segment Coalescing (RCS) is able to collect packets that are received during the same interrupt cycle and put them together so that they can be more efficiently delivered to the network stack. While this reduces CPU utilization and improves thorughput, it can also have a negative impact on latency. That is why we recommend you disable it where latency is more important than throughput.

Possible states: enabled, disabled, default. Default state: disabled Recommended: disabled for pure gaming latency, enabled for better throughput.

To enable using netsh:
netsh int tcp set global rsc=disabled
To change using PowerShell cmdlets:
Disable-NetAdapterRsc -Name * (use to disable RSC for all adapters) Enable-NetAdapterRsc -Name * (use to enables RSC for all adapters that support it) Get-NetAdapterRsc -Name * (use to view adapters that support RSC)

Notes: Only supported by some network adapters. May need "Checksum Offload" enabled as well to work.

Did you restart PC after all this?? When you restart, click right on game icon,go to compatibility and set run with administrator.
Do not set any windows to run in this option, disable that. We can test this again together.

I restarted with PC after this. However I was running in "Windows 8 Compatibility Mode".
I will try again later this week :)

:sms:

Ce message a pour but de résoudre les problèmes de lags en multijoueurs sur les Sudden-like et d'autres jeux anciens.
Le point particulier étant que le lag disparait dès que l'on coupe le son du jeu en question.

Une des solutions est de passer par une carte son externe mais cela n'est pas toujours efficace, c'est pourquoi nous vous proposons quelques astuces de configuration pour régler le problème à la source.

Pour Windows 7 :

* Ouvrir l'éditeur de registre (Win + X : regedit.exe)
* Aller dans : HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Multimedia\SystemProfile
* Trouver la clé "network performance throttling" dont la valeur par défaut est 10
* Mettre FFFFFFFF hex à la place
* Rebooter la machine

Pour Windows 8/8.1 :
* Ouvrir l'éditeur de registre (Win + X : regedit.exe)
* Aller dans : HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Multimedia\SystemProfile
* Trouver la clé "SystemResponsiveness" dont la valeur par défaut est 10 (10 signifique que au moins 10% des ressources sont reservées pour Windows)
* Mettre 0 à la place
* Rebooter la machine

Pour Windows 10 :

* Ouvrir l'éditeur de registre (Win + X : regedit.exe)
* Aller dans : HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces{NIC-id}
* Aller dans le dossier {NIC-id} correspondant à son adresse IP locale utilisée pour jouer (dans le cas d'un pc avec plusieurs interfaces, filaire+wifi notamment)
* Créer les clés TcpAckFrequency (valeur 1) TCPNoDelay (valeur 1) et TcpDelAckTicks (valeur 0)
* Aller dans : HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Multimedia\SystemProfile.
* Créer la clé Under "“NetworkThrottlingIndex”" (valeur ffffffff)
* Aller dans : HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Multimedia\SystemProfile.
* Créer la clé "SystemResponsiveness" (valeur 00000000)
* Aller dans : HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Multimedia\SystemProfile\Tasks\Games
* Trouver la clé "GPU Priority" dont la valeur par défaut est 8
* Mettre 6 à la place
* Fermer l'éditeur de registre et lancer l'invité de commande (Win + X : cmd.exe)
* Taper la commande netsh int tcp set global rsc=disabled
* Rebooter la machine

Attention suite à ces modifications, il convient de lancer le jeu en mode administrateur sans paramètre de compatibilité avec une version précédente.

Enfin une solution à ce problème récurrent sur certaines config' !
Merci Mayor et Love !;)

2 infos importantes.

1. Ces corrections permettent également de corriger les lags avec Teamspeak + les sudden et avec d'autres jeux (SS4/BK3)
2. Il faut penser à refaire les modifications à chaque mise à jour majeure de Windows (Fall Update, Creator Update etc.)
