Razer's claim that FrameSync technology syncs its mouse sensor to the display's polling/refresh cycle is backed by independent testing, which confirmed the core mechanism works as described, with only minor timing irregularities noted.

BUYING THE HYPE
▸ HYPE VS REALITY
Razer markets its FrameSync sensor technology, used in its latest esports mice, as syncing the mouse sensor directly to the monitor's polling rate and refresh cycle -- similar in concept to display-side technologies like G-Sync -- to reduce input latency and improve tracking consistency.
Independent testing reported by PC Gamer confirmed that Razer's FrameSync technology does what the company describes: the sensor's polling is genuinely synced to the reporting cycle, not just marketing language for a conventional high-polling-rate sensor. The testing did note some very small periodic timing intervals that weren't perfectly uniform, though reviewers concluded they weren't significant enough to undermine the overall claim. Some independent reports separately note a distinct, narrower issue -- a 'DPI downshift' quirk affecting some Razer mice -- that is unrelated to the FrameSync claim itself.
This is a rare case in gaming-peripheral marketing where a fairly technical, checkable claim was put to independent testing and largely held up. The minor timing irregularities reviewers found don't rise to the level of undermining the core claim, and the separate DPI-downshift issue reported elsewhere is a distinct quirk rather than evidence against FrameSync specifically. When a specific technical claim survives real scrutiny like this, it's worth saying so.
This verdict would change if new, credible evidence emerged contradicting the claim "FrameSync technology genuinely syncs the mouse sensor to the display's polling/refresh cycle." — for example, an independent test or investigation finding the opposite of what's currently confirmed.
▸ CLAIM CHECK
- PC Gamer — Independent testing confirmed FrameSync does sync the sensor to the polling rate as Razer describes, with only minor, non-disqualifying timing irregularities noted.

▸ FAQ
Does Razer's FrameSync sensor tech actually work as advertised?
Yes, according to independent testing reported by PC Gamer, which confirmed the sensor genuinely syncs to the polling/reporting cycle as Razer describes, with only small, non-disqualifying timing irregularities.
Are there any known issues with Razer mouse sensors?
Some independent reports note a separate 'DPI downshift' quirk on some Razer mice, distinct from the FrameSync claim itself, which independent testing otherwise confirmed.
