Roccat Leadr Wireless Gaming Mouse: The Rival to the Razer Mamba and Logitech G900 in Our Hands-On-Test

With its new Leadr, Roccat is launching its attack on the wireless sector. To aid it in that cause, it has been armed with the brand new Owl-Eye sensor that sports a whopping 12.000 DPI resolution as well as a lift-off sensor. The Hamburg based company is entering the 2,4 GHz game pretty late and thus has to compete with products like the Razer Mamba and the Logitech G900. But they have some aces up their sleeve in the form of Shark-Fins and X-Celerator-throttles. The Roccat Leadr in its first hands-on review. By Benjamin Kratsch.

Design wise, the Roccat Leadr borrows from the Tyon and brings with it all of the Tyons strengths: Good ergonomics, decent size, and a whole load of features. It offers an impressive 14 buttons, among which is the iconic shark fin, the “Hamburger, the X-Celerator thumb switch, and the thumb button named “Easyshift-Plus”. Roccat are staying true to their “more is more” philosophy with this one and keep including lots of buttons and controls on their mice whereas Logitech, for example, stripped down their G900 to only six buttons.

We were not able to have too many sessions with the Leadr but we found that Battlefield 4 fans will almost certainly be excited about the return of the X-Celerator as an alternative method for flying planes and helicopters. This feature is also available for controlling gun on tanks in Battlefield 1 while driving. It can also be used for switching between ducking and crawling without having to play finger-twister on your keyboard. If you want to make reloading feel more tactile and want to be less reliant on your keyboard you can also assign that task to the X-Celerator switch. You have to be careful though because if you simply let the switch snap back to the middle position it is likely the also trigger whichever command you assigned to the other direction.

Best Gaming Mouse 2017 (Full Buying Guide)

For most people, a mouse is just a mouse, but if you are looking for a perfect mouse, you know it is much more than that.

As I have already written in my guide about mechanical keyboards, there is no single product on which everyone will agree: everyone has their own preferences and, today more than ever, there are mouse for all tastes and budgets.

The most important factors when choosing a mouse are:

  • Grip, shape and size
  • Number and placement of buttons
  • Weight
  • Sensor (type, resolution, etc.)
  • Type of connection and response times
  • Quality of components
  • Extra features
  • Mousepad
  • Price (you cannot find a good mouse for less than 30 dollars)

Grip

The choice of the kind of grip is absolutely a personal one. There are 3 possible kinds of grip, and they all come with pros and cons. A good part of mouse are suitable for all grips, some are adjustable, while others are meant for only one grip. Put your hand on your mouse and choose wisely the grip that suits you the best.

Best Gaming Laptops under 1000 Dollars

A gaming laptop tends to have high-end processors, graphics cards, cooling systems, and displays which often result in its high price, but with the development of hardware, the current mid-range and high-end graphics are good enough for us to play some mid-range games smoothly. If you do not pursue the ultimate gaming experience, these mid-range graphics cards can even allow you to play some demanding games smoothly at lower resolutions. $1000 is a watershed of the gaming laptop, most of which, with midrange graphics, are distributed around this price. What follows is a recommendation of several popular gaming laptops within the $1,000 range and with a high performance-cost ratio.

Currently, the NVIDIA remains the mainstream in the market share of mid-range and high-end graphics cards. The AMD graphics mainly focus on the low-end laptops in the market share (most of them are integrated graphics). So, if you want to buy a laptop around $500, the AMD graphics card is your first choice. The APU platform has a very good gaming performance, and secondly, there are virtually no laptops equipped with the NVIDIA graphics within this price range.

AMD FreeSync vs. G-Sync: is AMD FreeSync a Efficient and low-cost Variable Refresh Rate Technology?

You probably remember that our first experience with FreeSync was, to say the least, disappointing. We would like to remind you that behind the name FreeSync lies AMD’s answer to Nvidia’s G-Sync, that is to say a technology for the handling of variable display refresh rates. The idea behind this concept is that it helps to improve the game-play experience by providing an increased sensation of fluidity. How is FreeSync doing these days you might ask? As long as the proper monitor is used, it actually works quite well and costs quite a bit less than G-Sync!

AMD FreeSync

After much fanfare in January 2014, the arrival of the first FreeSync compatible monitor had to wait until March of 2015. And, unfortunately, their performance was far from impressive. On paper, the advantages offered by this technique of monitor management were many fold, starting with the fact that it relied on an open technology standard which is much less costly than that of Nvidia’s G-Sync. However, entry-level monitors which didn’t provide the required fluidity left us feeling disappointed with the whole concept.

Adaptive-Sync, FreeSync and G-Sync

Under the banner of these three terms, or brands if you prefer, lies the technology for the management of variable refresh rates (VRR). A classic fixed refresh rate of 60 Hz will offer an imperfect visual experience when playing video games. As each image is different, it follows that the time required for the calculation of each image also differs. This discrepancy results in synchronization problems. While a higher refresh rate, of 144 Hz for example, decreases the impact of the problem it does not eliminate it entirely. The graphics card might miss a display cycle, spend too much time waiting for the next cycle or disregard a cycle entirely, all of which will result in image breakup (tearing).

What is the difference between RAM and ROM?

Computers and mobile devices need two main types of memory in order to operate correctly and to store the data that they work with. These two types of memory are known as RAM and ROM, and we are going to analyze in detail each of their differences and in what way each one stands out.

RAM

The first one is RAM, which stands for Random Access Memory, and as its name indicates, constantly changes its content. This is usually the second component with most memory on our device, after the hard discs or SSD, followed by the graphics cards. RAM is used to store the programs and data that the CPU is using in real time, hence the term ‘Random Access Memory’.

The 5 Best Image Compression Software

Two months ago we explained how to compress files, particularly how compression works for several files, including images. This is something that’s been gaining importance in the last years, especially in big companies like Google or Facebook, since images just keep getting larger, and they are doing it at a faster pace than any company’s servers and hard drives, so compressing is a must.

The best options to compress your photos

It’s common to rely on websites to perform these functions, but if we don’t have a fast internet connection the process can be too slow. We also have Windows’ Paint or Photos, which compress the file of an image 20% if we save them, and in Paint we can even edit their size. The problem is that they barely have any customization options.

Single Rail or Multi Rail PC power supplies, which one is better?

Many, many times in this website have we talk about power supplies and each time, we have mention rails as something common without going to deep about them. Well, that ends with this article in which we are going to explain what rails are, how they affect PC performance and if it’s better to choose a power supply with a single and powerful rail or one with several.

PC power supplies

In this article we’ll try to be as comprehensible as possible for people who don’t have any electronic or electrical notions, so we warn you if you do have this knowledge don’t be alarmed by seeing how rough this explanations are, since our aim is for this to be completely understandable for every user, having in mind that the purpose is to help choosing which option is more convenient whether a single rail or a multi rail power supply.

What are power supply rails?

First of all, let’s explain what a rail is. Rails are the channels through which the power supply feeds electricity to all the components in our computer. Generally we just talk about +12 V rails since these have the bigger impact in the computer but power supplies have also rails in the +3,3V y +5V channels of course.

PC power supplies

Single Rail vs Multi Rail

Each rail of the power supply has an overcurrent protection (OCP) and is limited to one OCP per rail, this way if our power supply relies on just one +12 V rail, it will have one OCP as well. This means that everything we plug into the power supply will have the same rail and therefore just a single protection, so if any problem were to happen and the power supply protection fails, every component connected would be at risk.

PC power supplies

In the other hand we have a multi rail power supply, which will have an OCP in each rail. So, not only can we divide the current by components (for example, on one rail the motherboard and processor, video card in another, and in a different rail hard drives) but also if something fails not every component will suffer the consequences, just the ones connected to that rail.

Pros and Cons

We’ll start by saying that you should not be alarmed; modern power supplies have lots of safeguards no matter how many rails they have. The first advantage of having a +12 V single rail power supply is that you will be able to feed more alternating current, and as you know, specially video cards need a minimum of intensity to work. For example a GTX 1080 NVIDIA graphic card needs a +12 V rail not only to provide certain power but also to supply a minimum of 30 amps of intensity.

Best Antivirus for Windows

Regarding antiviruses, there are a plethora of logical options. We all use the internet differently and inn order to help you choose, we’ll determine which security suite suits which user profile.

After closely analyzing most of 2016’s suites, one thing is for certain: these solutions have a rather limited impact on performances, and their efficiency is superior to the basic defense tools built into Windows 8.

We have noticed a trend: suites include more features, including PC optimization, and take into account the diversity of devices in the household. But, besides BitDefender, all the publishers must do better integrating their mobile solutions and offering the possibility of controlling everything from a single interface.

Intel Core i5-7600K vs. i7-7700K: for a few more MHz

Today Intel is launching its new line of desktop Core processors – the so called “7th generation” Kaby Lake line. As we have previously mentioned, the innovations in CPU technology offered by these new chips are pretty limited, the major innovation is their increased operating frequency.

i7-7700K

The Core i5 and Core i7 Kaby Lake range is composed of:

  • i7-7700K : 4C/8T, 8 Mo LLC, 4.2-4.5 GHz, 91W, 339$
  • i7-6700K : 4C/8T, 8 Mo LLC, 4.0-4.2 GHz, 91W, 339$
  • i5-7600K : 4C/4T, 6 Mo LLC, 3.8-4.2 GHz, 91W, 242$
  • i5-6600K : 4C/4T, 6 Mo LLC, 3.5-3.9 GHz, 91W, 242$
  • i7-7700 : 4C/8T, 8 Mo LLC, 3.6-4.2 GHz, 65W, 303$
  • i7-6700 : 4C/8T, 8 Mo LLC, 3.4-4.0 GHz, 65W, 303$
  • i5-7600 : 4C/4T, 6 Mo LLC, 3.5-4.1 GHz, 65W, 213$
  • i5-6600 : 4C/4T, 6 Mo LLC, 3.3-3.9 GHz, 65W, 213$
  • i5-7500 : 4C/4T, 6 Mo LLC, 3.4-3.8 GHz, 65W, 192$
  • i5-6500 : 4C/4T, 6 Mo LLC, 3.2-3.6 GHz, 65W, 192$
  • i5-7400 : 4C/4T, 6 Mo LLC, 3.0-3.5 GHz, 65W, 182$
  • i5-6400 : 4C/4T, 6 Mo LLC, 2.7-3.3 GHz, 65W, 182$

Compared to the previous line of processors, we can see an increase in operating frequency of between 200 and 300 MHz thanks to the “14nm+” technology Intel has incorporated into the new chips and all for the same price as the older generation. For all practical purposes however, due to the novelty factor and the absence of non-official suppliers, we can expect a temporarily increased retail price. It should be noted that these processors officially support DDR4-2400 RAM whereas the previous generation is limited to DDR4-2133, except when overclocking with the Z chipset – in which case they easily exceed DDR4-3000.
