Razer Synapse 4

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

Sound quality on my Razer Kraken headset has become completely terrible. I’ve tried uninstalling Synapse 4, turning off all effects in the control panel, etc. I’m about ready to throw away this headset and buy a new one from a different company. Is there a cleanup tool that will delete everything and then I can try again before I throw this in the trash? This is so disappointing considering how expensive this headset was.

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. 

With a lot of people moving from Windows to CachyOS and other Linux distributions, I am yet another person asking the question of Razer:When will you provide official support for Razer products and Synapse on Linux? 

I formatted my PC a few minutes ago and wanted to install Razer Synapse, but when I try to open it, I get an error (RazerSynapseInstaller.err). Inside the folder, it says (Failed to write installer file (Permission denied)).I’m running Windows 11 and have already disabled the firewall and antivirus, but it still isn’t working.I look forward to a reply.

I can't add any games to Linked Games. The games are visible in the list (under the + button), but nothing happens when I click the "ADD" button. When I find the game (exe file) myself using "Browse", nothing happens either.This feature is essential and if you have multiple profiles, you can't set anything up automatically!Does anyone have the same problem?Can anyone help?Thank youOperating System: Windows 11 Pro 24H2 (build: 26100.3194)Razer Synapse: 4.0.86.2502180127Connected hardware: Huntsman Elite, Naga Pro, Mouse Dock Chroma

I want my CTRL key to also send U key presses, but I want it to keep it's original behavior. My Corsair keyboard has an option called "retain original input" which makes it exactly do what I want.I tried to setup a macro on my CTRL key in razer synapse but the issue is it will send CTRL and U but then I cannot "hold" CTRL (to crouch in-game for example), it blocks the original behavior completely.Is this not possible in synapse ?

I'm using a Razer Blade 18 2025 laptop. How do I set Razer Synapse 4 to not overwrite the icm color profile I added in Windows 11? I set the color profile via color management in Windows 11, save it as the default profile. After restarting, whenever Synapse 4 starts, it overwrites my profile with the default profile in Synapse 4. It worked fine for me on the previous installation, but I don't know why it's not working for me now? I noticed that I previously had a custom color profile filled in directly in Synapse 4, but now there is an empty field, see the picture. I'm using a graphics card in optimus mode. Can you please help me? Thank you! 

I ran into an issue with Razer Synapse 4 not showing wireless battery percentage for 2 different wireless models. Both are listed as officially supported and backwards compatible with Synapse 3 and both had the same exact issue with no battery percentage displaying. I uninstalled Synapse 4 and reinstalled Synapse 3. BAM! I can now see all wireless mouse battery percentages. I attempted to troubleshoot with support but it took way too long to get valuable responses and I’m not interested in downloading a software log capture tool. Will check out Synapse 4 at a later date perhaps.I thought I’d post this for anyone who has a similar problem as all of the threads I’ve seen are requesting PM’s and don’t show a resolution status or troubleshooting steps.

So, I currently play gta online and hear to music while I play, I currently have a razer huntsman v2 as my main keyboard and I use the razer sypnases 4 software since I also have other razer products.The issue is that when I play gta online, for some reason the media keys act as a other keys. For example: The previous song acts as a Q, which makes me to change radio, a bit of annoying sometimes. The Stop/Resume song, acts as the G, which makes blow C4’s, also annoying And the skip song, acts as to pause the menu, which is more annoying.I have found out that is mainly the razer sypnase 4 software since I have tried to play gta without and it doesn’t happen, and no, I don’t use any macros and either my default profile of the keyboard has no change.I honestly don’t know how to fix this, maybe I should go back to razer sypnase 3 and wait till this issue is fixed?

When I turn on my PC every time and I open razer synapse, the program doesn’t detect my Razer Blackshark V3 unless I unplug and then plug back in the USB dongle. What should I do? 

Subject: Critical Installation Failure (Exit Code: 4294967295) and Device Detection Issue - Razer Viper V3 ProTo the Razer Support Team,I am writing to report a persistent technical issue regarding the installation of Razer Synapse (both v3 and v4) and a device detection problem with my Razer Viper V3 Pro.The Problem:Despite being a developer-level user and trying multiple advanced troubleshooting steps, I am unable to install Razer Synapse 4 via the standard installer or Windows Package Manager (Winget). I consistently receive the following error:Error: "Installer failed with exit code: 4294967295" (Equivalent to Exit Code -1).What I Have Already Attempted:Environment Variable Redirection: I redirected both User and System TEMP/TMP variables to C:\Temp to bypass any path or permission issues.Clean Reinstallation: I have completely purged all Razer folders from %AppData%, %ProgramData%, and wiped Razer keys from the Registr

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?

This functionality was promised to be ready with Synapse 4’s public release, so why it is still not available?

This used to work fine, but for the past few weeks (probably following an update), Synapse now opens to the desktop after Windows starts.I’ve checked the setting in Synapse, and turned it off and back on.I’ve also checked the Run registry setting which appears to be correct."C:\Program Files\Razer\RazerAppEngine\RazerAppEngine.exe" --url-params=apps=synapse,chroma-app --launch-force-hidden=synapse,chroma-app --autoStart=1Generally, Synapse 4 has been more stable this year and having release notes at long last is a welcome improvement. Just a shame I now have this new bug.

Beta name was removed, but beta quality was not. Give it more months to cook.

For many years in synapse 3 I had Excel linked to special profile. After migrating to synapse 4 few months ago I was unable to do so, so had to roll back to S3. Now, few weeks ago I tried S4 again and it worked this time. But today it stopped working. In the linked games tab excel was shown with comment "game not found". I deleted it from the list and tried to re-add it. For some reason when I choose Excel.exe with "brose" menu nothing happens, and it returns to the menu of linked games.That is very frustrating for me, since Excel profile is the most important function in synapse for me.

Hello,I recently purchased a Razer Wolverine V3 Pro, and I am currently unable to use it properly due to a critical issue with Razer Synapse.The controller is detected, but Synapse is stuck on "Loading" / "Syncing Profiles", and no changes are applied to the device at all. This makes core features like remapping, RGB, and stick calibration completely unusable.Key Issues:No settings are saved or applied to the controller RGB lighting does not change Button remapping does not work Stick calibration and deadzone adjustments do nothing Synapse remains stuck syncing indefinitelyMajor Concern:The required Synapse services are missing entirely from the system:Razer Synapse Service (missing) Razer Central Service (missing)Only the following services exist:Razer Elevation Service Razer Game Manager Service 3

Does anyone elses keys mapped to volume not change the volume more than one step when you hold it down? This only happened recently, which im assuming is from the update and it doesnt occur when using a saved profile when synapse is closed

I buy a viper mini this month.but it can’t connect to synapse4. how should i do guys

Ok, so this is probably a dumb question but how do I associate a Chromo Studio profile with a keyboard profile on my Blackwidow v4 Pro Keyboard in Synapse v4? I used to be able to do it really easily in Synapse v2 (I skipped v3). To be clear when I change to keyboard profile 1 I want to display  only the QWERTY keys in green and everything else in blue. When I change to profile 2 I want it to display only the QWERTY keys in blue and everything else in green. Simple (and not real) example but I can’t make it work. I don’t want the change to be linked to a specific game, the only thing changing is the keyboard profile. I can make it work if I select quick effects in the lighting tab but when I select Advanced Effects it doesn’t save different choices under the Chroma Studio dropdown. I’m sure I am missing something obvious but for the life of me I can’t see what. Thanks in advance for any help you can give
