Razer Synapse

I'm experiencing an issue after logging into Razer Synapse. There's an undeletable default app profile that seems permanently saved in the cloud. It syncs back to my local device every time I log in, and it sometimes prevents me from adding new profiles.

Hi everyone,I've been experiencing multiple serious issues with my Razer BlackShark V2 HyperSpeed running Synapse 4 on Windows 11. I've already had the headset replaced once – the problems are identical on the new unit, which confirms this is a software/firmware issue, not a hardware defect. 1. Dongle not recognized on startupWhen I turn on the headset, it is frequently not detected by Synapse or Windows. I have to physically unplug and replug the HyperSpeed dongle to get it recognized. This happens consistently and is reproducible.2. Volume extremely low until a profile is selectedEvery time I power on the headset, audio is barely audible until I manually switch to or re-select a profile in Synapse 4. Only then does the correct volume apply. This happens on every startup.3. Microphone randomly stops workingThe microphone frequently fails to pick up audio. When it does work, the sidetone ("Abhören" / mic monitoring) feature does n

Tired of using Rawaccel every time I turn on my PC I need to open the program. I want to ask you guys when is Razer going to enable me to fix the rotation of my mouse? Or the hardware is limited and the Razer programmers will not make my Deathadder v3 Pro have mouse rotation? I already sent two feedbacks months ago and still no mouse rotation feature. I need to know so I can make up my mind to buy another mouse with mouse rotation built in.

Synapse for Mac is relentlessly opening the system settings, prompting me to grant it permissions that it has absolutely no business asking for.I’m using a mouse with no RGB lighting, so Screen & System Audio Recording is unnecessary. Full Disk Access? Seriously? That’s a huge ask for an app that adjusts my mouse sensitivity. I don’t even need Bluetooth access, because this mouse has a dongle. It’s one thing to ask, but when the app is open, it constantly pops open the dialog asking for these things, and if you focus the window, it will open the related pages in the system settings. It’s extremely intrusive.

You ruined my ability to make lighting profiles. Haptics have been a huge mess. I'm done. Can't take the abuse of the new Razer. You never finished supporting Lian Li still missing 26 Led fan option for Lian Li TL LCD 140mm fans to be used with Razer Chroma Addressable RGB controller. I asked for Tartarus on large format RGB mousepads in 2019. That has been sitting in beta working for over two months. I told you Clio has low volume. Still not able to hear anything in game from this as a rear speaker. Works with Voicemeeter. I can have actual 5.1 and volume. Haptics are very unreliable and inconsistent. Hammerhead v3 hyperspeed offers THX Spatial Audio App yet isn't supported properly. https://youtube.com/watch?v=lobJbP2ArY4&si=P7vfhEfx1JmWhUab

My Razer mouse indicates 2 states via LED: 1. Awaked from sleep and no Synapse detected (Spectrum Cycling LED) 2. Synapse detected and just linked teh mouse (Switched profile’s color LED)Issue: My Razer BASILISK V3 X HyperSpeed does totally not remember my customized DPI and every awaking from sleep reverts its DPI to default. (400/800/1600/3200/6400 DPI) Then Synapse 4 applies my customized DPI list to my mouse again but it spends about 5 secs until the DPI reapplied so it makes me goes mad.The mouse works cool but its software’s awful and completely spoiling customer experiences.Do NOT tell me to update or reinstall Razer Synapse.

Hello all,On one of my PC Synapse 4 is not starting up properly.  During the startup phase, it is downloading files but it doesn’t complete.  It downloads files non-stop reaching 50 000 % + and keep rising. I have all the latest update of Windows 11and without any razer devices connected but it is always bug at this place. Anyone encounter this and have a workaround? Thank you!

Hi,My microphone is working fine but the RGB suddenly stopped working. I’ve tried multiple troubleshooting steps already but to no avail. It just happened yesterday. Troubleshooting Steps done:1.) Unplug and re-plug cable.2.) Uninstall and Re-install Razer Synapse/Chroma.3.) Uninstall and Re-install Seiren V3 Chroma Driver from Device Manager.4.) Turn on my PC with only the Seiren V3 Chroma plugged in.5.) Try all USB ports including a docking station on my PC.6.) Run my device with Razer Synapse/Chroma disabled. I don’t have an extra computer/laptop to try my device. Is anyone experiencing this as well?

The latest Synapse update (I had one yesterday I think) disabled the automatic profile switch for some applications. The profiles do not switch automatically for Google Chrome or VSCode, but they do work for others like Visual Studio or some games.I tried everything that was suggested in some support threads regarding the faulty profiles switch (there are lots of them apparently, meaning Synapse is quite buggy).Razer, please debug the latest release or give me a link to an older version of Synapse 4.

Now can switch ANC on/off or ambient, but cannot adjust ANC level in Synapse 4 version 4.0.86.2601160905 and beta version 4.0.86.2511170410.Synapse 3 and Audio app are correctly. Since 02-Nov-2024, I reported this issue to Razer Support staff.By the way, last month (10-Dec-2025) Razer Support staff replied me that they tried to fixed.What are Razer doing?

Linked Games and Auto Profile Switch no longer works after an Synapse Update (Jan 2026), profile switch doesn't affect the apps i'm using. i did a clean install to the software, the linked games now takes forever to scan games and i can't even add programs to it.

Hi everyone,My device: Razer Blade 18 (2024) – Intel i9-14900HX / RTX 4080 / Windows 11 Home I’m having an issue where Razer Synapse doesn’t start automatically with Windows, or if it does, it launches very late after the system boots. Until Synapse finally loads, my keyboard shows random lighting effects instead of my saved Chroma profile. Here’s what I’ve already tried (without success): Enabled “Start Razer Synapse on system startup” in the settings. Checked Task Manager → Startup tab (Synapse is enabled). Made a custom Task Scheduler entry to start Synapse at login (with and without delay). Set Synapse to run as administrator. Verified that Razer Synapse Service and Razer Central Service are set to “Automatic” and running. Reinstalled Synapse completely (including deleting leftover Razer folders from AppData and Program Files). Despite all this, Sy

The audio equalizare in Razer synapse 4 is not doing anything to my sound, cant modify anything, the problem started 3-4 days ago.

The problemAfter the recent Razer Synapse 4 update, somewhere around the end of April - the beginning of May, my laptop settings tab became completely blank.Exactly the same blank tab as in the image in the topic at the link:https://insider.razer.com/razer-synapse-4-55/kraken-v3-pro-tab-is-blank-70072?postid=236934#post236934Only in my case, instead of "kraken v3 pro" it was my laptop "blade 16".The solutionI managed to fix the problem this way:Delete the "Razer" folder in the directory - "C:\Users\%username%\AppData\Local\"; Open "System Settings -> Apps -> Installed apps -> Razer Synapse (three dots, click on modify)". Click "Repair" in the app that opens.The same actions can be seen in the following videos:https://youtu

Synapse 4 is garbage it doesn't work half the time and the other half it keeps crashing, i have never used such a buggy software in my life, its literally reseting all my profiles to default even if i re-import them or create new ones, if i switch profiles for a differnet game its keeps jumping back and forth from 1 to the other, why this is even available yet is beyond me, cant use Synaps 3 installer "Server access unavailable" im using the Razer Tartarus V2 and its completely un-usable with Synapse 4, why could they not allow us to use Synapse 3 locally i dont understand, those that still have synapse 3 can use it locally 

I’ve seen some others have had some problems with installing Synapse 4, but the fixes either I can’t implement because they’re too technical (using PowerShell) or they don’t work for me (closing any Razer processes in Task Manager).Does anyone have any recommendations for a fix that works and isn’t technical?

Hi, I’ve been trying to recreate Sequence Macro like functionality in Razer Synapse. But for some reason it doesn’t really work well. Any ideas what’s the best way to create a macro like this:  

g, h, j, k, o, p, [, ], c, TAB, LShift, CapsLock, Del, PGup, Numpad4, Numpad5. All have the blue LED disabled. The first day i noticed i was able to get it to temporarily fix itself by unplugging the keyboard , restarting synapse 4, and plugging it back in. but since then this issue persists, i know these LEDs are not burned out. they are just software disabled. I've tried firmware updating and factory resetting the Hunstman Elite. But i wish not to uninstall synapse if i can avoid it. When synapse is off and the keyboard is on default spectrum cycling the blue LEDs remain disabled.I am firmly certain this is a synapse issue but because my keyboard is out of warranty i was forced onto this forum instead of talking to a customer service person. Edit* Windows Dynamic Lighting is off, Razer is set to Chroma RGB.

Synapse 4 – Tartarus Pro 8-Way Input Issue (Still Unresolved)I’ve been dealing with an issue in Synapse 4 affecting the Tartarus Pro for nearly a year now.Functionality that worked reliably in Synapse 3 — especially 8-way directional input (diagonal movement) and simultaneous key combinations — is no longer usable in Synapse 4.Since Synapse 3 has been discontinued, there is currently no fallback option.The issue has been documented through multiple support cases (logs, video evidence, cross-system testing) and has also been reported by other users in the community.Most recently, Razer Support stated that it cannot currently be confirmed whether this behavior is a known issue or an intentional change — nor if or when the original functionality might be restored.After nearly a year, this lack of clarity is difficult to understand.Is anyone else experiencing the same behavior?Any feedback or confirmation would be appreciated.

In Synapse 4, Ultra-Low Latency mode is currently not usable. In the text description for it it says “… as low as ~10ms.When disabled, enjoy gaming grade latency ...” when in fact it should be “… as low as ~10ms. When disabled, enjoy gaming grade latency ...”See screenshot attached.  The forgotten space here makes my BlackShark V3 headset unusable because the absence of the space prevents me from enjoying gaming grade latency.
