Razer Synapse 4

I've got a basilisk v3 and I can't even use the sensitivity clutch on it. It's the one and only reason I got this mouse. But synapse takes a full 10 seconds to recognize that I've pressed it and then it just stays on indefinitely after I've pressed it. So it's a dysfunction at best and an absolute blockade of a hiderance at worst.

Using Razer Blackwidow v3 I have two profiles on my keyboard. The first one has 'x' and 'd' keys running a macro while pressed. The second is a basic normal keyboard.Whenever i use profile 1 (Macro) and switch to profile 2 (Normal), I am unable to hold the the 'x' and 'd' keys. It will only trigger the keypress once and stop after that even though i am holding down the the 'x' or 'd' keys. It has been affecting my gameplay, hence, why I am bringing this issue up.Example, after switching back to profile 2 (Normal), presses 'x' key and hold down, presses left arrow key, 'x' key stops registering.The other keys which doesn't not have any macro registered to it does not seem to have this issue.I did not have this issue when i was using synapse 3. It was only after i updated to synapse 4 did this starting happening.

I have several razer pheripherals. By defualt I have chroma set up so that a wave colour gradient from left to right goes across my devices. Since upgrading to Synapse 4, the way the wave travels is no longer smooth. I can visibly see the colours stepping from one shade to another as the gradient moves across the devices. The effect this produces is not nearly as pleasing as it looked when the gradient was smooth. I switched back to Synapse 3 and the problem is not there. Unfortunately it looks like the Wolverine v3 Pro isn’t compatible with Synapse 3 or I would stick with that. I don’t really understand how razer have managed to ruin this effect, but I’m wondering if anyone has the same experience or if we can expect a fix.

Before upgrading to Razer Synapse 4, I could hold the volume up button to increase the volume continuously. Now I have to keep pressing it repeatedly. However, when I close the Razer Synapse app, holding the button works normally again.Is there a way to keep the app open and still be able to hold the volume up button to increase the volume, without having to spam the button?

I recently had uninstalled razer synapse 4 and reverted to razer synapse 3 after hours of trying to troubleshoot issues with razer synapse 4 crashing over and over again but I decided to try to give it one more chance and for some reason I thought, what if I try continuing as guest when logging in? FOR SOME REASON, THIS SOLVES MY CRASH ISSUE. I tried logging in again and IMMEDIATELY the program crashes over and over again. I uninstall and reinstall and  but log in this time to find that, sure enough, it still crashes on startup repeatedly. Uninstall and reinstall and continue as guest- NO CRASHES. So weird I don’t understand why this would be the case, maybe there is a bug with the profiles syncing or somehow my profiles got corrupted or something, I don’t know,… I also don’t know if this will solve the issue long term, and would like to be able to sync profiles or have access to my old profiles saved to my account, but for now at least it seems to work as a temporary fix for the cr

I’m here simply to advocate for Linux support. I have 3 Razer devices, headphones, keyboard and mouse and they struggle to work with Linux. Us Linux users should not have to settle for third part software like OpenRazer. While I respect their work it should not be on them to have to make these tools. We paid money for our devices, we expect support on Linux. 

Hi everyone,I downloaded a macro script from Razer Synapse 3 and tried to use it in Razer Synapse 4, but it doesn’t seem to work.I noticed that normally the macro icon should show a red slash symbol when it’s active, but mine doesn’t show that icon at all. The macro also doesn’t execute when I press the assigned key.Has anyone experienced this issue before?Is Synapse 4 incompatible with macros created in Synapse 3, or do I need to reconfigure everything?Any help would be appreciated. Thanks! 

Blackwidow V4 Pro and Synapse 4 installed.If Synapse is running and I run other certain apps, like a music streaming app, multimedia keys don’t work there and volume control stops working. As soon as I exit the music streaming app, volume control shows up reacting to the roll bar with significant delay. But sometimes it stops working at all. Only if I exit Synapse, it’ll be working.I tried all the steps proposed by support documentation, like rei-installation of the keyboard driver, Windows update and clean re-installation of Synapse, but they didn’t work.

Hello all, Since using synapse 4 I've got some troubles with my profiles for minecraft Java. Normaly I add the Java file in my games and it works. But with synapse 4 it delete it from the game list after every boot of minecraft and when it doesn't delete it it put it graued out saying it doesn't find it.  Is there another way or do I have to roll back to synapse 3? Thanks in advance

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.

Razer synapse 4 is not running, i installed and deleted it but it does not work. When it was synapse 3 sometimes it couldnt recognise my Viper v3 pro and Blackshark v2 pro (2023)

Synapse 4 is not backwards compatible - causing ALL PROFILES TO BE ERASED. The interface is incredibly painful to use and customize for each game - many, many clicks to do what was quick and easy before.  UI/UX team should be replaced.  FAIL. Support refuses to respond.  After replying to reach request, they act like they didn’t get anything and send an email “we are closing your ticket for lack of response”  NO, you are closing it because you have poor quality, worse support, and garbage forced upgrades. THUMBS UP if you want Synapse 3 to have extended support until Synapse 4 has proper quality assurances and basic functionality including profile imports!  

Hi.I’m inviting all to conversation about never ending list of bugs in Synapse 4.Let’s open beers or more voltage alcohole like Razer DEV team and chat about issues with this app if we can call it an app.So last time I spent more time on Synapse 4 fighting with lights and synchronization with MSI app and gear than on playing or doing something more productive. What I learned is that application working like trowing a dice, each clean installation generate different problem :) fixing one but giving you new one.From what I notice there a 4 common issues:   Chroma app stopped turning on automatically with the system after login to windows account (to make lights on you need to turn on manually the Chroma app) Sometimes there is an issue where you can’t add games to Synapse 4 I notice also when you have set profile with lights for some specific game keyboard (huntsman elite in my cas

Hi all, and RazerThere has been many posts about Synapse 4 keep crashing,And there has not been any response from Razer at all. the problem is that i love the Tec that thay produce, but the Synapse 4 is not getting fixed !!! at all , at the moment. Can Razer please acknowledge that there is a problem, and what thay are trying to do to sort it out. The longer that thay dont give any response, it just sends a message, that thay dont seam to care !!.I dont think that is the case, but please respond Razer,because the longer  thay leave it, the more damage it is doing for there reputation . Thanks in advance Razer

Hello,I would like to report what appears to be a regression in Razer Synapse 4 regarding macro execution speed, compared to Synapse 3.I am using onboard memory profiles with macros created previously in Synapse 3.When Synapse 4 is completely closed, the macros execute instantly with no noticeable delay, exactly as configured (0 ms delay). However, as soon as Synapse 4 is running, a significant delay appears between macro actions - even when the macro itself is set to 0 ms delay.I have prepared two videos that clearly demonstrate this difference in macro execution speed:• Synapse 3 (fast / no delay): https://youtu.be/NsiYelsQUrk• Synapse 4 (noticeable delay):

I’ve got Asus Vivobook laptop, Windows 11 and Synapse 4 installed.Almost everything was just fine until one of the Windows updates.Sound became crackling, distorted with unstable loudness levels.I’ve tried everything, have texted to support: they just said that my earphones were faulty so I got to return them on warranty… I did it, got a new pair and..The issue is still there.Whenever I turn off “Turn on audio enhanements” in Windows settings the problem dissapears along with better sound, eq and stuff. So it’s not an option.So I tried the following:removed everything with razer tool installed synapse 3 instead of synapse 4Everything WORKS JUST FINE.Installed Synapse 4Issue came back.Also I’ve reinstalled every sound and chipset driver in System, manually clean registry and still no results.Seems like Razer Software can’t work properly with Windows up

1). I can't have mouse profiles on any of those open razer UI's, how to get there ?2) .. when you will support Linux customers as the first class citizens  ? .. or we should be paying for forever for our heresy to choose something better than Microsoft thing ?.

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

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.

Razer Chroma addressable RGB controller facing problem that Synapse 4 dont recognize my connected device every time i startup pc, need to manually click refresh the controller in synapse to let chroma studio knew there is rgb device.

I have a Razer mouse, keyboards, ARGB controller, and have recently purchased a Sieren V3 Chroma microphone. I really like Razer hardware, but I have had no end of issues with the software - particularly when it comes to using Razer Chrome to control RGB lighting. I have been using SignalRGB to control my LED lighting of late, and it just works. No effort, no issues - it just works. I can't however run Razer Synapse and SignalRGB at the same time, meaning that I lose other functionality provided by Synapse.My feature request - allow me to completely disable Chroma while still runing Synapse. I can then use something else to control RGB lighting while still making use of Razer Synapse features. 

Scroll toggle mode works slower in Razer Synapse 4 and I can feel a delay. In Razer Synapse 3 it worked better. I use a Razer Basilisk V3, Windows 11.

On a fresh install of Synapse 4, the mic volume for my Nari Ultimate headset keeps getting turned down from 100 to < 20. This has an impact on any application that uses the mic, such as Teams, Discord, et cetera.The only workaround I’ve found is to close out all Synapse applications.Is there any way to disable mic volume auto adjustment in Synapse?
