Windows 11 has come a long way from its infant stage. Today it is incredibly good and stable operating system that also looks good and modern. Unfortunately, fancy animations and good graphics come with a price, in this case, slower performance on some little older and weaker computers.
Animations itself which include also fading effects can sometimes feel slugging and laggy and have a general overall feeling of delay. For a more old-school instant experience, you can turn off animations.
In order to turn animations inside Windows 11 follow this simple guide:
First thing is to open Settings by pressing Windows + i key combination or you could open Start and in the search box type in Settings and then click on its icon.
Once inside settings on the left side find Accessibility and click on it to select it. Once it is selected on the right side choose Visual effects. Inside the visual effects section click on the switch next to Animation effects to OFF. You can also turn off transparency effects in this section if you wish if you have an older GPU in order to speed it up a little.
That is all you need to do, settings will be automatically saved and all animations will be turned off for a quicker and more responsive feeling when working inside W11
Nvidia announced the third generation of GeForce RTX GPUs called Ada Lovelace. New technology is bringing 76 billion transistors with 18,000 CUDA cores along with new gen ray tracing cores and improved Tensor cores as well. The new lineup also comes with DLSS 3 which is vastly improved from its previous version pushing a 4 times increase in frame rates over native rendering.
RTX 4090, a better model of GPU will come with 16,384 CUDA cores and a boost clock speed of 2.52 GHz. Also, it is packed with stunning 24 GB of GDDR6V VRAM. In Nvidia's words, its performance is twice faster than the 3090 Ti in games like Flight simulator, three times faster on Portal RTX, and four times faster on RacerX.
RTX 4080 comes in two modes, one with 12GB VRAM and a stronger one with 16GB VRAM but differences do not end here. The lower model is packing 7,680 CUDA cores while the stronger one is going to 9,728 CUDA cores. We will wait to see how will these cores count impact real-world performance in games.
As for prices, the flagship model RTX 4090 will be $1,600 USD and it will hit the market on October 12th. RTX 4080 12GB model will be $900 USD and the model with 16GB VRAM will go up to $1,200 USD. This, of course, is the price for Founders Edition cards, OEM cards from third parties like ASUS, MSI, Gigatech, etc will cost more.
“Like we’ve done on mobile, DuckDuckGo for desktop will redefine user expectations of everyday online privacy,”From everything that we have learned so far, the browser will be focused on making privacy super easy and simple, eliminating tons of different settings about privacy, and making the whole environment robust privacy protection all set by default. Settings will be applied in all fields, across search, browsing, email, and more. Gabriel also said that aim of the browser is not just a privacy browser, it is meant to be built and used as your everyday browser, for everyday use that protects your privacy as a bonus. One interesting thing that was stated is that browser itself is built upon OS-provided rendering engines instead of typical Chromium. DuckDuckGo says this approach will strip away a lot of the unnecessary cruft and clutter that's accumulated over the years in major browsers. Also, the company stated that when compared to Chrome, the DuckDuckGo app desktop is cleaner, way more private and that early tests have found out that it is significantly faster as well. Is this just corporate advertising or reality? We will see once the browser is released, or once it is released for public testing. Until then take care and happy holidays.
