Technology
All mice contain a small circuit board inside to handle the connection between inputs and the computer. Some are more complex than others, which is why these so-called Microcontroller Units (MCUs) are needed, which are essentially specialized miniature computers. Most modern mice today are equipped with more complex microcontrollers to manage things like stored profiles and CPI settings and to ensure a smooth connection, especially in wireless mice.
The resolution of a mouse, also known as CPI, indicates how many pixels the cursor on the screen moves when you move the mouse one inch on the mousepad or table. Many mouse manufacturers and some online sources use the term DPI to refer to the same thing. However, DPI stands for ‘Dots per Inch’ and refers more to screen resolutions, while CPI stands for ‘Counts per Inch’ and directly relates to the sensitivity of a mouse. The higher the CPI of a mouse, the “finer/more precise/more frequent” the sensor can scan the surface. However, this does not mean you should play with the highest CPI.
The polling rate, also known as the report rate, is the frequency at which the mouse communicates with the computer and makes inputs (responds). The polling rate is measured in Hz and can vary between 125 Hz and 8,000 Hz depending on the brand and model of the mouse in question. For example, a mouse with a polling rate set to 1,000 Hz will update its position on the screen 1,000 times per second, or every 1 ms. The higher the polling rate, the more “real-time” the cursor movement you see on the screen will be.
The Lift-Off Distance (LOD) refers to the height at which a mouse sensor stops tracking the surface it’s on. A high LOD means that the mouse continues to track even when lifted off the surface. Therefore, a low LOD allows tracking to stop sooner, preventing unwanted mouse behavior. On the other hand a higher LOD means the mouse will draw more energy which often results in a crispier feeling but for the cost of less battery life.
Many of the latest high-end gaming mice offer the option to enable Motion Sync, which synchronizes SPI reads with USB polling, resulting in less jitter. This feature is often found in PixArt 3370 or newer sensors. Motion Sync has its pros and cons, and whether or not to use it often depends on the games you play and how much you notice these extremely fine differences.
When correctly implemented, Motion Sync promises higher sensor reactivity by synchronizing the signals the mouse sends at the exact intervals the PC is looking for these data. This leads to more consistent data exchange, which helps in tracking targets better. However, while Motion Sync is enabled and the sensor tracks more consistently, it pushes data to the next polling event, leading to a minimal higher input delay of a few milliseconds, depending on the MCU and sensor used, which polling rate is utilized, and how much power the components are allowed to draw (LP, HP, Corded / God Mode). In short, Motion Sync is comparable to VRR technologies like G-Sync, where one must decide if they are willing to sacrifice a minimal delay for a smoother experience on the monitor.
I currently recommend disabling Motion Sync
Under each mouse button, there is a microswitch (switch) that creates the clicking sound and sends the input signal to the computer. A microswitch consists of an outer plastic housing and a small button connected to the internal mechanism. The inside of a switch contains a spring and two metallic contact points that close upon activation to complete the circuit. Currently, two types of microswitches are used in mice – the good old mechanical switches and the newer optical switches. What makes microswitches so essential for mice is that they require very little force to activate, often just 50g. Once activated, they respond almost instantaneously.
There are many manufacturers of microswitches. The more well-known ones include Omron, Kailh, Huano, Razer, and TTC.
Debounce is the time a switch takes to register a keypress or mouse click. In mechanical keyboards and gaming mice, the switch can “bounce” several times when pressed, causing the device to register multiple inputs for a single press. Debounce time helps eliminate this issue by ignoring additional inputs that occur within a predetermined timeframe after the first press. However, the higher the debounce, the higher the delay of the registered “clicks.” Therefore, one aims to have as low a debounce as possible without “double clicks.”

Click latency is the time delay between the physical click of a mouse button and the subsequent action performed on the screen. In gaming, this delay can significantly impact the player’s performance, especially in competitive gaming. For example, in first-person shooter games, the delay between clicking the mouse button to shoot and the action executed on the screen can mean the difference between winning and losing. Several factors can influence click latency, including the hardware and software used, the type of connection, and the computer’s processing speed. Gaming mice designed for competitive gaming typically have low click latency to provide a fast and responsive gaming experience. Some gaming mice also have customizable click latency settings, allowing players to adjust the response time according to their preferences.
The capacity of the battery is indicated in mAh, which stands for milliampere-hours. It is a unit for measuring the electrical charge stored in a battery. The higher the mAh number, the more charge the battery can store, and the longer it will last.
Important note:
The battery life always refers to the “best” mode that generally consumes the most power. This means:
- highest polling rate (e.g., 4,000 Hz)
- best wireless mode (e.g., 2.4G)
- best sensor mode (e.g., Comp-Mode on)
- RGB (on if available)

Miscellaneous
NVIDIA G-SYNC Displays with Reflex feature the world’s first and only System Latency Analyzer, capable of detecting clicks from Reflex-compatible mice and measuring the time it takes for the resulting pixels (muzzle flash) to change on the screen. Start every fight with the confidence and assurance that your PC is operating with the lowest possible system latency.
Paracord is typically a woven or braided (not to be confused with traditional heavy braided cables) nylon cable, used in a variety of applications. Paracord became famous for its use in the military and climbing industries and is considered incredibly durable. When used in gaming mice, Paracord cables are usually lighter than traditional mouse and braided cables. The light design and flexibility allow for more freedom of movement, resulting in easier movements and quick pivots during gameplay. Besides the lower weight, Paracord also offers less “cable drag” because nylon has lower friction. Combined with a mouse bungee, the negative aspect of using a wired mouse practically disappears for most users. However, it’s noteworthy that not all wired gaming mice include a Paracord cable, and not all Paracord cables are the same. This is important to consider when purchasing a new mouse, as a wireless mouse may still be lighter or more free in movement.

Logitech has solidified its position as a manufacturer of top gaming gear in the market with the update of the successful G PRO X SUPERLIGHT. The Logitech G PRO X SUPERLIGHT 2 once again features first-class build quality and has received a few small updates. In addition to a new sensor, new switches, and a slightly larger battery, the weight has also been slightly reduced, finally breaking the 60-gram barrier. This is particularly advantageous for competitive players who desire optimal speed and agility.
The successful simple shape/design has not been changed, only the connector has been updated and is now finally up to date with USB Type-C, which allows for faster charging and eliminates the need for an additional cable to charge your hardware. After all, let’s be honest, 95% of all technical devices, whether gaming gear, mobile phones, etc., are charged with USB-C these days.
The new Hero 2 sensor, which now allows for a polling rate of 2,000Hz in addition to 32,000 CPI/DPI, is of course a highlight. Why Logitech does not deliver 4,000Hz yet like the competition, for example with the Razer Deathadder V3 Pro, remains a mystery. The sensor & the wireless implementation work together with the Nordic nRF52840 MCU, and thanks to the slightly larger battery with 290mAh, the battery life of 55-60h is passable. Of course, 200h would be even better, but who plays through for so long, and a larger battery would also mean more weight. I think Logitech has found a very good compromise here. Unfortunatley there are some polling instability issues at the moment of testing and its unknown if Logitech will be able to fix these with a firmware or software update. *UPDATE: Logitech released an update in March 2024 that now allows for a 4,000 Hz polling rate without the need for an additional 4K dongle – I have not yet been able to conduct a retest at this time )
You now have the option to calibrate the sensor (the CPI/DPI) with your old mouse, so you have the same sensitivity, & the lift-off distance is adjustable in 3 stages. You can make all the usual settings via the software as usual & save them to various profiles or directly to the mouse. It is also possible to use the new optical Omron switches (called Logitech “Lightforce Hybrid Switches”) either in optical mode or in hybrid mode. The hybrid is supposed to convey a mechanical feeling & also save some power. My conclusion here: WELL… use the optical mode, because the new switch does not convey the familiar feeling of the Superlight 1 switches (Omron 20M) at all, and the click delay doubles in hybrid mode. I personally like the new switches, but this is always a matter of personal taste, and I have heard several other opinions. In the end, if you really want to, you can install & solder your personal favorite (watch YT tutorials). It remains to be seen how good the durability is and whether the switches “wear out”. Double clicks should not be possible due to the optical implementation and the otherwise very solid design.
Otherwise, not much has changed, the weight was reduced by a few grams, the mouse wheel is exactly the same as before, and the, in my opinion, unnecessary Lightspeed charging technology, as well as the “holder” for the wireless USB dongle, are still present. Here again, you could certainly save another 5-10 grams if you, like me, prefer as light mice as possible and want to mod your mouse. The implementation of the glidetaps is unfortunately once again absolutely unworthy of a mouse in this class. An even worse PTFE was used (at least it feels that way) and only the shape was slightly changed, making it impossible for you to use your “old” custom skatez…. STRONG UPDATE @Logitech…
In summary, I must say that although Logitech has brought an update to the predecessor to the market with the GPX SL2, a real WOW effect is missing. The sensor is still great but unfortunately does not have 4K yet and has polling instability issues, the new switches are a matter of taste & about 4 grams less weight is now not the absolute madness. The skatez are garbage – but here I expected nothing, so as always buy good ones directly, because you can’t use the old ones due to the new design. The mouse costs a fair amount more in RRP compared to the predecessor and therefore I cannot recommend an upgrade to anyone who currently has a Superlight 1. Economically, it just doesn’t make sense. However, anyone who is still playing the old G Pro Wireless or is generally looking for a TOP gaming mouse will have a lot of fun with the Superlight 2! In the end, shape is king and this is a very good choice for many players & grip types with the Logitech G Pro X Superlight 2.
