News: About the NVIDIA DLSS 2.0

This past week, NVIDIA announced an update to its Deep Learning Super Sampling technology, aptly dubbed DLSS 2.0.
Deep Learning Super Sampling named DLSS is an NVIDIA RTX technology that uses the power of AI to boost your frame rates.
DLSS essentially takes lower-resolution imagery, and intelligently upscales it to looks like native, higher-resolution output.
Performance was universally improved to varying degrees since the game was being internally rendered at a lower resolution, but image quality wasn’t always optimal and sometimes resulted in unwanted artifacts.
The old DLSS 1.0’s effect on game visuals and performance was a mixed bag, that varied from title to title.
The new DLSS 2.0 comes with DLSS 2.0 improved the quality, balanced, and performance by leveraging the Tensor cores available in its GeForce RTX-series GPUs.
Let's see one example:

Unity 3D : About VFX Graph.

The official webpage of the VFX Graph for Unity 3D comes with a short intro.
The install steps can be seen on this webpage.
I started today to follow one video tutorial about fire and smoke from youtube channel named Brackeys.
This video tutorial can be seen here:

Some conclusions about my test with an old video card:

• you need a good video graphic card;
• you need a unity version with Package Manager;
• I found some new changes using with the Unity 3D version 2019.3.5f1;
• many changes in the 
• the one is the Output Particle Quad with many changes into variables;
• I cannot set the TotalTime, this crash it all;

The result is this:

The settings for this smoke effect using the Visual Effect Graph Asset can be seen in the next image:

Partsim online circuit simulator.

PartSim is a free and easy to use circuit simulator that runs in your web browser.
I create today my account to see how better is this online tool.
You can build, test and simulate your e with a SPICE Simulator, AC/DC/Transient Sims and Waveform Viewer.
The Arrow Integration lets the PartSim include an integrated Bill-Of-Materials manager that lets you assign Arrow Part Numbers to your models.
You can see many examples on the official website:

• Bipolar Differential Amplifier;
• Simple CMOS Inverter;
• OpAmp Transient Full-wave Rectifier with Smoothing;
• Capacitor;
• Passive Low Pass Filter;
• RC Charging Circuit;
• Differential Amplifier
