35. What are the best TCP Optimizer settings for gaming ?

While the SG TCP Optimizer is designed to give you the best possible throughput online, it can also help improve your gaming experience. There are, however a few subtle differences when optimizing for throughput/file transfer vs. gaming/reduced latency.

To tweak your system for the best possible gaming performance, please follow these steps:

1. Apply the Optimal Settings
In the TCP Optimizer, set your advertised internet speed, choose the "optimal" settings, and "Apply" them (you can postpone the reboot for now).

2. Set Network Throttling Index
In the "Advanced" tab of the Optimizer, set the "Gaming Tweak - Network Throttling Index":
NetworkThrottlingIndex: disabled:ffffffff
SystemResponsiveness: gaming: 0

3. Disable Naggling
In the "Advanced" tab, set the "Gaming Tweak - Disable Nagle's Algorithm":
TcpAckFrequency: 1
TcpNoDelay: 1
TcpDelAckTicks: 0

4. Apply the Optimizer settings and reboot when prompted.

5. More Tweaks
After applying the settings and rebooting, also see the Gaming Tweaks article for additional settings to your PC and NAT router not covered by the program.

Some of the Optimizer tweaks affect both TCP and UDP.

Hi, when optimal settings are applied the other step options are greyed out, I had to select custom to be able to follow the remaining steps. But doing so changed all the other optimal settings also.

I guess the solution would be set all the optimal settings in custom, short of changing the program, I look forward to hearing from you.

Thanks for writing. You should apply the "optimal" settings first (you don't have to reboot yet), then go back and make any "custom" settings as you see fit.

'apply ... then go back' here meaning, close and reopen the app, wasn't evident to me upon first read.

Hi, I would like to know if this can reduce ping, and if it is safe?
by anonymous - 2019-06-04 08:56
Yes it will

Is this still relevant? does this even lower game ping?
some ppl say this makes network worse. I mean is the "optimal" settings really optimal for people all across the globe? no diffrences between countries?
All i do is to disable all the power saving stuff, green ethernet etc.

It is very relevant. The speed difference is not as great as with older OSes, however tweaks still work for most types of broadband internet connections.
