What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
There is no single officially recommended DPI or polling rate for every game or PC. Start with a DPI that matches your previous mouse, choose a polling rate that feels responsive and works reliably with your system, and adjust lighting or performance choices when longer runtime matters. The settings below distinguish Razer’s published capabilities from practical starting guidance.
What you can configure in Razer Synapse
Razer says Synapse can configure DPI, button mappings, macros, scroll modes, Hypershift functions and Chroma lighting. The Basilisk V4 Pro has 14 customizable controls, but that is a hardware capability—not a requirement to remap every control.

Synapse also supports Smart Polling Rate switching, which lets you set polling rates for games and adjust behavior according to the active game. Menu labels and availability can vary with software versions, so use the current Synapse controls rather than relying on a fixed click path.
Choose a DPI that supports your control
The mouse uses Razer’s Focus Pro 50K Optical Sensor Gen-3, with support for up to 50,000 DPI. That maximum describes sensor capability; it is not a recommended gaming setting. Razer does not prescribe one best DPI in the reviewed product materials.

Start with a familiar setting
If you are moving from another mouse, Razer specifically promotes matching its DPI as a starting point. This avoids changing a familiar sensitivity at the same time as you learn a new shape and controls.
Adjust gradually when needed
If aiming or cursor movement feels too fast or slow in a particular game, change DPI in small increments and play long enough to judge control. Keep the game’s own sensitivity setting in mind: changing both DPI and in-game sensitivity at once makes it harder to tell which change helped. The right balance depends on your preference and game; the product specifications do not establish a universal value.

Pick a polling rate for your game and system
Razer lists support for up to 8000 Hz polling in both wired and wireless modes. A higher maximum is an available capability, not proof that every game or computer will benefit from using it. The reviewed sources provide no independent performance test or universal numeric recommendation.
Choose a rate that feels responsive and operates reliably with your setup. If you use different rates for different games, Smart Polling Rate switching can select a rate according to the active game. Otherwise, a fixed rate you prefer is a straightforward starting point. Avoid treating the top setting as automatically best.

Balance connection mode and battery runtime
Razer’s published maximum battery figures differ by wireless connection mode. They are manufacturer claims, not standardized comparisons or guaranteed runtimes; Razer says actual battery life depends on use and settings.
| Connection mode | Razer-published battery figure | How to use the figure |
|---|---|---|
| HyperSpeed Wireless Gen-2 | Up to 200 hours | Maximum claim; actual runtime depends on use and settings. |
| Bluetooth 6.2 | Up to 275 hours | Maximum claim; actual runtime depends on use and settings. |
| Wired | Not stated in the reviewed Razer materials | Use a wired connection when you prefer not to rely on wireless runtime; no comparable battery figure is given. |
These figures should not be read as the result of a controlled cross-mode test. Choose a connection mode based on the responsiveness and convenience you need, then treat runtime as dependent on your own usage.

Settings to reconsider when battery life matters
Razer says battery life varies with settings, but the reviewed materials do not quantify how much any one adjustment saves. Treat these as choices to review, not guaranteed battery-saving fixes:
- Chroma lighting: Reduce or turn off lighting if it matters less to you than runtime.
- Polling behavior: Use a per-game rate that meets your needs rather than selecting the maximum by default; Razer does not publish a precise battery saving for a lower rate.
- Connection mode: Consider Bluetooth when its convenience and stated maximum claim suit your use, while remembering that real runtime still varies.
Razer’s product blog describes Frame Sync as coordinating sensor scanning with the polling cycle. It says this can capture movement data closer to transmission to the PC, helping reduce motion latency while improving battery efficiency. That is Razer’s explanation of its technology, not an independently measured latency or battery result: Razer’s Basilisk V4 line announcement.

A practical setup sequence
- In Razer Synapse, set DPI to match the mouse you are replacing, or choose the familiar value you already use.
- Test movement and aim in your usual game. Adjust DPI in small steps only if control feels wrong, and avoid changing the game’s sensitivity at the same time.
- Choose a polling rate that feels responsive and works reliably. If you want different behavior by game, configure Smart Polling Rate switching.
- Map only the buttons, scroll modes, macros or Hypershift functions you expect to use; set Chroma lighting to suit your preference and runtime priorities.
- Select wired, HyperSpeed Wireless Gen-2 or Bluetooth 6.2 according to your needs, without assuming the advertised maximum runtime will match your use.
Razer’s published specifications and what they establish
Razer’s 2026 product materials list up to 8000 Hz polling in wired and wireless modes, a Focus Pro 50K Optical Sensor Gen-3 with up to 50,000 DPI, and 14 customizable controls. These figures describe capabilities, not settings that every player should use. Razer’s Synapse guidance and product details are on the official Basilisk V4 Pro product page. The same manufacturer materials state the conditional battery maxima above; they do not provide independent best-setting measurements or an exact runtime gain for changing an individual option.
