Razer Synapse 4

Hi Razer Team,I just created this account specifically to share some feedback on Synapse because I really love Razer products but find Synapse a bit heavy and resource-consuming. On my PC, it added 2 seconds to the startup time.If you co-optimize Synapse with teams experienced in deep system optimization — like the Ghost Spectre developers who make Windows lightweight and snappy — I believe Synapse could become way more efficient and user-friendly without losing features.If the Ghost Spectre team could make Windows 11 feel like Linux, imagine how much those people can optimize Synapse.Even a “Lite Mode” version of Synapse for users who want just the essentials would be an awesome start.Thanks for listening!Looking forward to seeing Synapse evolve.

I am trying to get Synapse 4.0 to automatically change profiles, and it works for most games and programs. “Star Trek Online” is an exception.  Like several other games, Synapse automatically detects the *launcher* (“Star Trek Online.exe”) and adds it to the game list.  If you associate this with a profile, Synapse will change profiles only when you’re at the launcher.  It will then change back to whatever was selected before hand when you get past the launcher.  It also does this for FFXIV, but I was able to manually associate the game executable with the profile in addition to the launcher executable.For Star Trek Online, it simply refuses to let me add the “GameClient.exe” (the actual game) to the list of apps and games that can be associated with profiles.  If you remove STO from the games list and attempt to add “Star Trek Online.exe”, it’ll add that without a problem.  If you try to add “GameClient.exe” from the x64 subdirectory (this is the version that’s

Does this happen to anyone else and has anyone found a solution?I was having no issues with just my Naga V2 Hyperspeed mouse, but now that I've added a Deathstalker V2 keyboard, I find that Synapse frequently loses its connection with the mouse (as seen in the first screenshot). Then I restart Synapse and it regains the connection (second screenshot).I'm using Bluetooth and the mouse still moves and clicks, but my macros and the application switching do not.not working before restart working after restart 

Сразу по истечении гарантийного срока исчезло 2/3 освещения у коврика для мыши Razer Strider Chroma. В чем могут быть причины? Можно ли его отремонтировать? Я отношусь к нему очень бережно.

I have a lot of ideas for Synapse 4 and I think you are reading this have at least thought in something amazing for the community or for the software, or both.So, why not create a Category here in this forum exclusive for ideas like yours and mine?So people would vote and discuss making the community engaged in and helping the staff and devs to understand whats their community want and need the most.What you think? 

Hello. Tell me, why i can`t change game mode   in Synapse 4 when switching profiles? Let's say I want to have a game mode set in one profile, but not in another profile! In Synapse 3, it worked !  as well as at the start of Synapse 4. But now! It doesn't work! And the  game mode cannot be configured differently in different profiles. Fix it!Everyone has this problem.This is the reason why I and many others have to stay on Synapse 3.

Not sure when this problem started, but it must have been within the last ~2 months.Current Synapse version is 4.0.86.2505230700Completely uninstalled, rebooted, and reinstalled Synapse already without any change.I can create macros normally in the Macro module, but when attempting to assign a macro to a mouse button the entire Synapse screen apart from the top menu goes blank until pressing F5 to refresh the tab.Currently unable to assign any macro to the mouse, severely limiting the product usage.Sounds similar to what is reported in this other thread.

Is there any possible way to disable Auto Updates in Synapse 4 & Chroma?I am finding Auto Updates are causing to many system issues & I would rather choose when to update.

So, when I map macro/some of multimedia options, it doesn’t work and says “This mapping requires Razer Synapse”. I tried reinstalling, rewriting macro, nothing worked. Is there and solution?

I have an Asrock Z690 Taichi Razer edition motherboard. The list of supported devices doesn’t include motherboards and since I’ll lose all my profiles from synapse 3 if I were to switch to 4 right now I’d rather not experiment and see if my motherboard is supported. Is this motherboard supported and are there plans for the motherboard to be supported if it isn’t already?  sorry for the title spelling I’m on mobile and clearly can’t type. 

since upgrading to synapse 4, it stopped saving some settings correctly eg. keyboard game modeheadset THX spatial mode 

In these recent updates this feature got bugged, it still works just not as intended. to verify this I went back to synapse 3 for testing purposes and there it worked as intended.I like to use the M1-M5 buttons as my very specific controls for some games and this bug completely breaks it,For example, I like to bind my M3 to Alt  (which is a jump key for the game in question), now when I use the regular Alt key I can jump while moving to the right (pressing right arrow key). Problem is that when i rebind my M3 to work this way, it just does NOT do the same thing. I tried all the available options, in any configuration I might add, be it key recording, alphanumeric or any other option) it just won’t work as the actual key anymore. Any thoughts/ideas or workarounds would be very helpful.  I use a Razer BlackWidow V4 Pro

Hi everyone,I just purchased a Viper V3 Pro. The Dongle sometimes might not show the light indicating my mouse battery after I open my computer. Sometimes when I wake up my computer from sleep the Dongle also showed no light of my mouse battery as well; but the mouse is still working. Then, I have to unplug the Dongle and plug it again and it works fine. And sometimes I cannot wake up my computer from sleep using the mouse and the dongle as well; sometimes it works sometimes it doesn’t. I don’t experience any connectivity issues during gaming or using. It’s just something happen at the beginning like when I first start my computer or waking up from sleep oor trying to wake the computer from sleep. I already reinstall synapse4, update firmware, pairing etc, but it still happens. Is this a software issue or hardware issues? Should I RMA?

I’m currently using 2024 Razer Blade 14 and updated to the latest version of Synapse 4 on May 7th. Immediately after the update, I started experiencing the following two issues: Since the update, there's a bug causing the volume of THX Spatial audio to be lower than the set level. I usually set the volume to 8 with THX Spatial audio enabled. However, after restarting the laptop, even though the volume setting still shows 8, the audio output is noticeably lower. Upon investigation, I determined that Synapse 4 is causing this issue. Changing the sound setting in Synapse 4 from THX Spatial audio to Stereo and then back to THX Spatial audio temporarily fixes the issue, restoring the volume to its correct level. There's also a firmware update notification bug. When opening the Synapse 4 app, I receive a notification indicating that a firmware update is required, providing the following online link:

I have been experiencing this issue where some of my keys on my “BlackWidow V3” keyboard stop working sometimes but in a super weird way. I’m pretty certain that it’s and issue with Synapse 4 because the key’s immediately start working again after I focus the Synapse application. From what I noticed is that it only effects lower case “h” and “c” and possibly “k”. When the issue occurs I can type the uppercase variant’s, of the before mentioned keys, just fine but still get no input when lowercase until I tab out of the game and refocus the Synapse application. It makes me wonder if this issue could be caused buy “Full-screen Windowed” games/applications because I stumbled into similar Issue while using OBS and an eye tracker where the stream video would bug out the second the game was tabbed back into (Counter-Strike 2). Some other person experienced the same exact issue but in Call Of Duty. So in both of those games, they have quite a few compatible issues caused by t

MY HEADSET DOES NOT APPEAR IN THE SYNAPSE PROGRAM, WHAT SHOULD I DO?   

headphones still cant load, profiles are still broken, and it crashes every 3 seconds. no Im not sending logs or anything, the last time I did that I was told there is nothing wrong. waste someone else's time.

Ive tried multiple times to install, reinstall, clean, etc.  All the suggestions provided including trying to install previous version.  No matter what, synapse doesn’t recognize the laptop.   

All Cryo Pro Ultra Resolutions within the Synapse 4 Camera Processing tab are for NTSC - ie they are all 60/30 FPS. I am in the UK and require resolutions for PAL - ie 50/25 FPS, for camera input into the software I use.Although I set the image anti-flicker to 50Hz, as used by PAL, the Synapse resolutions don’t change to suit.Any chance of an update or info’ how to use the camera on PAL sytems?

Currently, when a macro includes a long delay (e.g., 90 seconds), it becomes impossible to interrupt or restart the macro during that delay. The macro must finish the full wait time before any new input — even from the same hotkey — can trigger a new loop or restart the macro. This behavior limits responsiveness and flexibility, especially in scenarios where the user needs to adapt mid-loop. Please consider adding functionality to: Interrupt or reset a running macro immediately, regardless of how much delay time remains. Optionally allow delays to be non-blocking, so pressing the assigned macro key again can cancel or restart the macro on demand. This would dramatically improve the responsiveness of macros with long or variable delaysThank you for your work and continued updates to Synapse!

Hi. I’m bought Razer Naga V2 Hyperspeed and never use Razer before. I create Macro with “5+Left Click” and assign to mouse button with Play while assign key is press ( I think it’s same “repeat mode” in LG Hub).I found if i press hold macro button then release , sometime it stop at “5” left click not come after that. on LG Hub if i press hold then release macro it’s always call “5+Left Click” every-time no interrupt. Do I make something wrong with Synapse 4? or it’s normal thing for Razer Synapse 4?

When I download synapse 4 and transfer my profiles, my macros that worked when I was using synapse 3 do not work correctly and are imperfect. For example, in a game, when I set the weapon to not ricochet, it does not control the weapon ricochet correctly, what is the reason for this and how can I solve it? 

The problem is there no delay when i press media up first register and the following registers, so unless i click and release real quick, it raise or decrease volume by 4 level instead of just 2. This was not like that back when i was using Synapse 3. It happened with synapse 4. Razer keyboards (especially with Synapse 4) often send rapid repeat signals for media keys (volume up/down), with almost no initial delay — unlike most other keyboards, which typically have a built-in delay before repeat kicks in (just like regular typing keys).Synapse 4 lacks a setting to adjust repeat rate or debounce time for media keys — unlike some other manufacturers (e.g., Logitech with G Hub or QMK-supported boards).
