The internet is, unfortunately, home to numerous forum posts that divulge outdated information and incorrect analysis. We will attempt to debunk some common myths about gaming mice related to DPI, accuracy, mouse sensitivity and more. Mouse technology can be pretty complicated for everyone to understand, so we will try to keep it as simple as we can. Let’s get on with correcting some of the most widespread misconceptions when it comes to gaming mice technology. We hope that this will give you greater clarity to gauge what matters and what doesn’t when you are about to make that purchase.
The difference between optical and laser-illuminated sensors is basically how much information is picked up by each sensor. LED sensors in optical mice pick up the information on the very ‘top’ of the surface without being overly prone to the texture. On the hand, laser-illumination is more sensitive, so the sensor picks up the slightest details including bumps, rough edges and more. Therefore, laser-illuminated sensors work splendidly on hard surfaces, but on soft pads with a much more surface depth, they tend to pick up too much useless information. This can lead to disparities in how exactly they track at variant speeds. According to reports, laser-illuminated sensors show a 5-6 percent variation when it comes to tracking at different speeds, while the best optical sensors, in the same area, show less than one percent. So, optical sensors do track speed variations better than laser sensors, but the understanding of the technology behind this is usually flawed.
Now to the technical stuff. Imagine that a CMOS sensor array in a mouse uses pixels that are 30 micron big, then the resolution would be about 840 DPI or CPI, which is the number of counts the gaming mouse makes with an inch of movement. However, a mouse that has around 8400 DPI doesn’t always have pixels that are ten times smaller. This is a misconception. Sensor DPI increases often happen because of subdividing these pixels. In this situation, higher DPIs can be bad news. Cranking the DPI to ridiculous levels can cause issues such as contrived movements, resolution error versus speed (often known as ‘acceleration’), cursor ripple and more. Therefore, a higher DPI is not always good unless it has been optimised and created to support the jump in numbers.
Additionally, wireless mice declutter your desk by eliminating one wire that often gets tangled. In a day and age where wires are hoarding up because of the sheer number of devices that an individual possesses, going wireless is quite an elegant solution. Try to keep the mouse away from disturbances like the signal from phones, routers and other devices to ensure a seamless and smooth experience which is almost indistinguishable from a wired mouse.
When it comes to mouse sensitivity on Windows, the 6 out of 11 setting often brings you the closest to a 1:1 performance between how the cursor moves on the operating system and the actual data from the mouse. Surprisingly, changing your Windows mouse settings most likely will not matter for games at all! Reason? Most modern games utilise direct or raw input instead of WM_Input for mouse controls. They completely bypass the Windows mouse settings rendering this useless today. Not just today, games first began to ignore the Windows mouse settings around 15 years ago.
There is absolutely nothing stopping you from implementing these settings on your mouse through Windows mouse settings even now. However, if you were doing it merely to enhance your mouse’s performance in gaming, chances are it is not going to work since these settings are usually controlled in-game now.
The Logitech MX518 was released in 2005 and it is, by far, one of the most beloved gaming mice in history. However, it is far from being the best today. Developments in current-generation mice such as higher DPI (even though this isn’t always a good thing, but plenty of mice achieve DPIs higher than the MX518 without sacrificing performance), higher polling rates, better material design and ergonomics far exceed what the MX518 is capable of.
A feature called prediction or angle snapping was present on this mouse. Unfortunately, this is one of the most detested features in gaming mice today since it smoothened out mouse movements and allowed users to move in a straight line. Which is obviously something you would want to avoid in gaming at all costs. In gaming, a 1:1 correlation between your movements is desired. A mouse predicting your path would absolutely deter you from this. Gaming mice today have the option to enable this function if needed, but it remains disabled by default in drivers. Whereas, the MX518 shipped with the feature on by default and there was no option to turn it off. The horror!
The most important factor when it comes to buying a mouse is the comfort. Be wary of the shape and buy something that is comfortable for you. Secondly, make sure the sensors are top-notch and devoid of acceleration and smoothing. Try not getting caught up with the numerous myths surrounding mice and stick to what really matters.
