• Razer worked on weight, sensor and battery while Logitech rebuilt the click.
• The Viper V4 Pro is 49 grams and aimed straight at esports.
• The G Pro X2 Superstrike replaces its switches with a tunable haptic click.
• Both hit 8,000Hz wireless with no added input lag you can feel.
• The winner depends on which of three player types you are.

• Cheap mice now carry the sensors that were flagship-grade one generation ago.
• Sub-60g weights and 8,000Hz polling have both moved down the price ladder.
• Shell, skates, battery and software are what your extra money buys.
• Sensor specs stopped being a useful buying signal about two generations ago.
• Pick by grip, weight and the games you play, never by the DPI number.

• The DeathAdder V3 HyperSpeed weighs 55 grams, down from 63 on the Pro.
• It also lost 7mm of length, so large hands get less to hold.
• Across the 2026 field, the lightest mice are usually the smallest ones.
• The DeathAdder V4 Pro is the exception, staying big at 56 grams.
• Pick the shape that fits your hand, then pick the lightest one in it.

• The Superstrike ships UHMWPE feet, where the Superlight 2 used PTFE.
• Logitech says the swap buys durability, and reviewers say it costs glide.
• PTFE barely resists the first millimetre of movement, so nothing sticks.
• UHMWPE lasts several times longer, which is the whole reason to fit it.
• A replacement set costs under ten dollars and peels off again.

• Piper is the window you click; libratbag does the talking to the mouse.
• Your mouse is configurable only if libratbag ships a file for it.
• None of libratbag’s 120 device files cover a Razer mouse.
• Check the supported list before you hand over any money.
• ratbagctl does the same job from a script, with no window.

• At 1000Hz your mouse reports every millisecond; at 8000Hz, every eighth of one.
• The whole gain is 0.875ms, inside a chain that runs to tens of milliseconds.
• 2000Hz grabs most of that gain for a fraction of the CPU load.
• 8000Hz now ships switched on, so the real question is whether to leave it.
• Your CPU and frame rate decide the right tier for you.

• Every mouse report interrupts the CPU, so 8,000Hz means 8,000 interrupts a second.
• A Ryzen 5 5600X can lose 5 to 10 percent of its CPU to that stream.
• Fast modern chips shrug it off; older six-core builds stutter.
• The damage lands on your 1 percent lows, so averages hide it.
• 2,000Hz or 4,000Hz keeps most of the benefit for a fraction of the load.

• The mouse weighs 49g in black and 50g in white, down from 54g.
• The 180-hour battery rating assumes 1,000Hz polling.
• Switch to 8,000Hz and the rating falls to 44 hours.
• Eight times the polling costs about four times the battery drain.
• Two reviewers found no shell creak. Loud clicks are the real complaint.

• Unpowered, the Superstrike’s buttons give no click and no push back.
• The click comes from a tiny motor, so no power means no feel.
• There is no DPI button on the mouse, so setup needs software.
• Switch-based rivals still click fine on a flat battery.
• Ask what a peripheral does with a dead battery before you buy.

• The Superstrike swaps click switches for a haptic engine.
• Coils sense the press, motors make the click you feel.
• No switch means no double-click failure later on.
• Tom’s Hardware and Club386 both call the click slightly round.
• Logitech publishes no click-life number for the haptic parts.
