We may have to change the way the program reads RSS and RSC at startup, we just have to test which OSes are compatible (and correctly display) Get-NetOffloadGlobalSetting.

Some Windows versions/builds had discrepancies in what is returned with netsh vs PowerShell cmdlets for some of the settings, hence the mixture of methods used by the program. We will likely resort to using PowerShell, at least for newer OS variants.

The TCP Optimizer has been updated to version 4.0.9.

It now reads RSS and RSC at startup via PowerShell. We also changed the way they are applied to the global PowerShell setting. The recommended optimal RSC setting was changed to "disabled" as well, as it is better disabled for gaming/latency and Wi-Fi adapters.


Djfe and ukue, please confirm if it now correctly reads RSS and RSC on startup with your international Windows variants? Thanks in advance.

[Djfe]

yes, it works

It works now! thank you so much for your work!!

Thanks for the feedback, glad it's working now

Philip,

Can we also check the LSO. In my case it doesn't read it right in Windows 10 PRO x64. Tried experimenting with it. Enabled it using poweshell and the app still reads it as "disabled"

[Ashdaw]

The new version works really well Philip.

Not all adapters support LSO.. What is the ouput of this PowerShell cmdlet in your system?

Get-NetAdapterLso -Name *

[MagikMark]

I disabled it for now

Mark, this should be read correctly. In order for us to troubleshoot it further, can you please copy the command output and paste it into a text file, then email it to me ( philip @ sg ) ? Thanks.

one minor problem with latest version of TCP Optimizer. It seems to "mis-identify" Windows 10 Pro v1803 as "Windows 10 Enterprise build 17134" on one of my computers



it should be updated to correctly recognize the proper edition of Win10 v1803 RS4 version

[Philip]

Thanks for the info. The build number is correct (17134.254), just the "Enterprise" wording is incorrect.

Seems this is a Microsoft omission. Reading from the Windows Registry, the 32-bit location of "ProductName" shows the correct "Windows 10 Pro" wording, while the 64-bit equivalent shows "Windows 10 Enteprise" :

32-bit: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProductName
64-bit: HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\Windows NT\CurrentVersion\ProductName

[Philip]

It has been updated to properly read "Pro" instead of "Enterprise", if you re-download the exe from our site. There are no functionality changes, so the program version was not changed from 4.0.9.

My download of this tool has the apply link greyed out. My Optimizer looks like the ones already posted with the apply link greyed out. Is this supposed to be that color, or should this novice click elsewhere?

[Djfe]

You need to choose settings first
by selecting checkboxes at the bottom of the program

Optimal is a profile that selects the values of which the author of this program thinks that they are more optimal than the default ones of windows

Custom allows you to set each variable to values that you prefer

you can also do optimal first, then apply it and then customize it afterwards

Thanks. That worked. Now to test the program. Should any visible changes be noticed?

How visible the changes are depends on your line. Problematic connections, older OSes, in the presence of packet loss, etc. will have a more visible change right away. Fast, working connections, close to the advertised speed limit will only see visible difference in connections to more distant servers even though the connection is better optimized on your end.

Hey there, this tool needs upgrading... since it can only optimize for up to 100 mbps. What about those of us on 1GB speeds?

[Philip]

Hello vgchat,

It is 100+ Mbps, including 1GBps. The same settings are applied for 100Mbps and up. The only difference would be bumping the TCP Window auto-tuning algorithm even higher (from "normal" to "experimental"), nut we've found that it makes PCs unstable in high-speed transfers, as it can consume too much memory unnecessarily, and it also causes issues with local LAN shares transfers.
