PCI-E SWITCH ARBITRATION

Everything about latency. This section is mainly user/consumer discussion. (Peer-reviewed scientific discussion should go in Laboratory section). Tips, mouse lag, display lag, game engine lag, network lag, whole input lag chain, VSYNC OFF vs VSYNC ON, and more! Input Lag Articles on Blur Busters.

Sorry my English bad. I write briefly.
Realtek -> Bad
Intel -> Good
I checked many times.
I have no issues with Realtek. However the i-225v was a pain to work with.

Now Intel I-226V -> built-in and Intel(R) Gigabit CT Desktop Adapter -> discrete
Discrete better. Driver and interaction.

That is absolutely false.

It has been discussed for years on this forum. There are numerous topics with multitude of users reporting "worse" cursor feeling with Intel NICS compared to Realtek NICS. { Check here : viewtopic.php?t=10624 }

Even simply removing the Ethernet cable from the back of the motherboard makes your cursor faster when you have intel NIC. Putting the cable back in your motherboard makes the cursor slower.

This is without even talking about about the I219V, I225V and I226V that literally have hardware flaws due to fundamental engineering and silicon-level issues. Those hardware design flaws could not be fully resolved via software or firmware alone.

Just to names a few :

Irregular Interpacket Gap I219V, I225V an I226V controllers had issues maintaining proper timing/gap between packets per the IEEE standards. This pointed to PHY clock/timing bugs in the silicon. Link detection and initialization failures; boards with those intel NICS often failed to detect a plugged-in ethernet cable on boot or after sleep, requiring disable/enable cycles. And so many more...

These aren't minor driver bugs, they are silicon-level errata that Intel documented.

The last "good" consumer level Network Internet Card that Intel made was the Intel i211-AT.
