One of the most hated words in computing and one that makes many hardware engineers think is latency. Latency is the cause of some of the lag or poor performance of some systems. However, you can make use of this fantastic open source tool that will help you reduce latency. His name is LatencyFleX, and it can work independently of the provider and the video game you are using.
It is an alternative to NVIDIA Reflex, a proprietary software for gaming in Microsoft Windows that only works for the products of this company. Instead, with LatencyFleX you can use it for all kinds of hardware (works both on an NVIDIA GPU, like AMD, and even Intel) and natively on your GNU / Linux distro.
The project is not only a great alternative, but the developers are ambitious, and they already plan enable game developers to integrate it also in their game engines, beyond Unreal Engine and Unity 3D.
Regarding its effectiveness, you can see in the previous graph what is the latency with LatencyFleX on or off. And, as you can see, the latency measured in milliseconds drops considerably when active.
On the other hand, as I have already mentioned, the most positive thing is that it is free and open source. Is it availabe under Apache 2.0 license, so you can use it, distribute it, modify it, or whatever you want, always within what the clauses of this license allow.
Of course, you should use it at your own risk if you use video games with Anti-Cheat systemsas it might generate some problems. However, I suppose that little by little the problems will be polished and the project improved in every way.
