Demon Slayer -Kimetsu no Yaiba- The Hinokami Chronicles Improve your local network

Game Settings

Before to struggle with your local network, check the optimal settings for your game.

Graphics

Vsync : Off

Anti-Aliasing : Low to High

Textures : Low to High

Shadow : Low to High (never use Maximum because it consummed a lot ressources of your GPU and can produce slowdown)

Motion Blur : Low to High

Glare : Low to high

Resolution Display : As you want

Windows Display : Fullscreen recommended (but you can use borderless. In borderless you will be limited to your display windows resolution)

"Vsync will add a lot of input lag but frame limiting is much more negligible. Basically keep vsync off but limit the frames"

Nvidia Graphic Settings

This is what i use for the game in Nvidia 3D parameters.

Choose the program to custom.

Most importants settings are :

Frame Rate Limiter for the game : 30 FPS (important to have a good and stable frame times)

Prefered Refreshrate : Use the 3D application setting

Vertical Sync : Use the 3D application setting

Maximum pre-rendered frames : Application-controlled

Triple buffering : On

Power management mode : Optimal performance

Low latency : Ultra

Others settings that you can change if you want :

Antialising - Gamma correction On

Antialising - Mode Application-controlled

Antialisaing - Transparency Multisampling : Disabled

Enable MFAA Off

Anisotropic filtering mode Application-controlled

Texture filtering - Negative LOD bias Allow

Texture filtering - Quality Quality

Texture filtering - Trilinear optimization On

Limit Your Framerate To 30 Fps When Playing Online

60 fps unofficial modification doesn't let you sync and work with online mode.

So your only option is to keep the 30 fps but you need to have a stable 30 fps with a good frame times.

You can download MSI Afterburner and RivaTuner to have a good visibility on your frame times, fps, input lag.

Note : both the NVIDIA driver fps cap and the RTSS cap add about a frame of lag to games

Low Latency option in the Manage 3D settings menu :

Off = 2 or 3 frames

On = 1 frame

Utra = 0

Optional Refresh Rate Choice

From blahblah :

"Some misunderstandings about what vsync and gsync are and why it works here but may not work for you if you try to do the same:

First gsync and vsync off are designed to give you a smoother experience if you are unable to render at the monitor refresh rate. It doesn't help maintain a 60 fps rate, and in this scenario it only helps because the montior is 144hz.

Vsync means vertical synchronization, your monitor is always drawing at your refresh rate from top to bottom (vertically). Vsync waits until the drawing is starting again from the top before drawing. This is a regular interval, 1/60th of a second on a 60hz refresh rate, and if you miss that boat because you were taking too long to draw, you have to wait for the next one, which is going to be 2/60th of a second from the last update. e.g. 30 fps. This means that your 60 hz monitor is actually only able to render at a constant 60,30,20,15,etc fps rate.

vsync off means it doesn't wait for this interval and will instead just switch to the next frame mid refresh, giving you the screen tearing effect. g-sync means it will refresh on demand, just getting rid of screen tearing, but will actually increase latency (vs no vsync) because it still has to wait for the previous frame to finish drawing.

Now as for 144hz, this actually hurts you when you are trying to run at 60 fps. This is because your monitor still has sync times of 1/144 of a second. If it can't draw at 144hz, the next down is 72hz, then 48hz. Notice how neither of these are 60hz, so frames will either be present for 2 or 3 refreshes giving you a choppy feeling. Simply set your monitor to 60 hz and eliminate this as an issue.

Also if you do not have gsync, same thing."

Performance Mode

"In Manage 3D Settings in the Nvidia control panel, you can change your Power management to Prefer Maximum Performance. This keeps your GPU clocks from bouncing around and disturbing your fps/stability, but you will see a higher power draw and more gpu heat.

In windows 10, search for the "choose a power plan" option. On (intel) desktops, you have Power Saver, Balanced, and High Performance options by default. Choosing High Performance will keep your cpu clocks steady a their maximum Turbo boost 2.0 clocks as long as your system can handle the load. For gaming desktops with a $20-30 aftermarket cooler, this is easy. Most laptops not so much."

Hard Reset Of Your Network Adapter

In cmd.exe command, type :

ipconfig /release => release all connections

ipconfig /flushdns => purge dns cache

ipconfig /registerdns => refresh all dhcp leases and register again dns names

ipconfig /renew => renegotiate an ip address lease with the dhcp server on your router.

netsh winsock reset => recover the computer from any socket errors which arise when you download some unknown file / reset settings of your network card

restart your computer

Informations :

"netsh int ip reset is a command in windows to reset the TCP/IP. TCP/IP stands for transmission control protocol/Internet Protocol, it is a type of protocol used to communicate with other computers. If TCP/IP is not functioning then you would not be able to browse, even though if your computer is able to ping other Ip addresses and still if you are not able to pull up any webpages then reset the TCP/IP by using the above command.

netsh winsock reset is a command in windows to recover the computer from any socket errors which arise when you download some unknown file, or due to some malicious script on the computer.

Winsock settings contain your computer's configuration for Internet connectivity. Winsock errors can occur when the settings get corrupted, usually because of spyware or Web browser hijacking. If you are having trouble opening websites, it could be due to corrupted Winsock settings. "

Lan Wired Is Better

Use Lan wired ethernet instead Wifi connection because you will lost some packet with interferences.

You can check the difference notably with a great loss of bandwith in upload bitrate speed when using wifi connection.

To have less input delay too, prefrered to plug in your controller instead to use wifi or bluetooth to avoid interference.

Add An Exclusion Of The Game Folder

Add an exclusion for the antivirus in game folder :

It works for windows defender but you will need to find the process for another antivirus :

Change Your DNS Prefered

You can try to use Google DNS for resolving name servers.

It can improve the time to searching resolve name servers.

Preferred: 8.8.8.8

You can also use cloudfare dns servers that seem more faster than google dns :

How to Check Game Ping with Task Manager in Windows 10

https://www.windowsdigitals.com/check-games-ping-latency-windows-10/

Test Your Bandwidth Speed

Improve your local network - Network is not magic ! image 105

Open your navigator and navigate to google and search "google speed test"

Click on speed test to have your download speed, upload speed and your ping from a near location.

Test Your Ping

Delay is representative of multiple factors. Some packets loss between you and the server can produce some delay in game. Because some packets need to be resent with TCP (protocol).

https://youtu.be/25vu-0KL-WY

First, you need to test your ping to check in your local network if you have packet loss.

What is important is to find if you don't have packet loss in your 3 first destinations :

1 - Your device (computer) to your router (ipconfig and take the default gateway to have your next destination, your router or another device connected to your computer)

2 - Your router to your modem

3 - Your modem to your first initial head end in your town

Ping is just a communication with a question and an answer between two devices.

1 - Simply, go to your task bar in Windows and type cmd.exe.

2 - Launch cmd.exe in administrator mode

3 - Type ping -4 -n 25 www.google.com => It will show 25 requests with important informations here :

Octets sent

ping in milliseconds between your network adapter to one of the google's servers.

You can also use ping -t and stop it with ctrl+c (keyboard).

https://youtu.be/VPdotNIXOgI

4 - Check if you have some spikes between all theses requests (example, you have regularly 5 ms and you see like 20-30ms)

So next thing is to determine if you have some packet loss (some data lost) during the route of your packets.

1 - pathping -4 -w www.google.fr

At the end, it will show you if you lost some packets during the ping.

You can also use a program like Colasoft Ping Tool or Pingplotter (free trial) to check your packet loss to a server.
