Razer Synapse

Just build my new PC. with a fresh copy of Windows 11 Pro and  download a fresh copy Synapse 4. I have a Tartarus V2 and a NagaV2 Pro. The profiles appear to migrate from Razer Cloud storage. Downloaded fresh copies of my games to new a NvMe drive. I go to test one of the games with the New Synapse 4 and nothing happens. I see all the profiles and Marcos. I tested manually changing to the game’s profile. The profile seem to load but if I press the button the default key action happens. This happened the last time I tested upgrading to 4. I immediately deleted it and went back to 3 with zero profiles issue. I guess something is not functioning properly but I’m not aware of anything else that is needed. For the initial upgraded I followed the step to do it and it failed just as bad.  Any advise other then going back to 3 since it’s near end of life? Thanks in advance.

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. In fact, I haven’t been able to enjoy anything at all after identifying this.ProductSynapse 4Software Version4.0.86.2512101100 REPRODUCTION STEPSConnect any Razer headset product that is compatible with Ultra-lo

hi i just got new leviathan v2 x and the chroma visualizer audio is not working property when the beat light is not at the middle of the speaker pls help me

I want a Synapse macros that (of my Tartarus V2) switch to another keymap and also switch to a different Chroma effect for each keymap. Given that the commands SWITCH KEYMAP and SWITCH CHROMA EFFECT cannot be inserted in macros, I've tried the following workaround.In each keymap I've mapped a key (e.g. key 01 of Tartarus) to SWITCH KEYMAP (from keymap 1 to keymap 2, from keymap 2 to keymap 3 and from keymap 3 to keymap 1) In each keymap I've also mapped another key (e.g. key 02 of Tartarus) to SWITCH CHROMA EFFECT, i.e. a different Chroma effect for each keymap (e.g. "static orange" in keymap 1, "static green" in keymap 2, "static blue" in keymap 3). I've created a macro in which I've recorded they keys mapped above (e.g., on Tartarus: "press key 01, release key 01, press key 02, release key 02"). In each keymap I've mapped a third key (e.g. "ALT" key on Tartarus) to that macro.When I press myself the keys, they work (e.g. in keyma

This was buggy on Synapse 3 and broke in beta. So, grateful to see Synapse 4 was taken out of beta with all the bugs included too.. And even more bugs, as things that were half working now completely don’t anymore.. Awesome progress 😂 Problem: Actuation key travel adjustments do not save, and stay at the default 2.5mm, even when setting all keys using the sync all keys to say the max 3.6mm... it will still stay at 2.5mm!!! This is the most annoying bug, as it has literally removed a major functionality from the device. So, I’d be very grateful if it could be fixed. Then maybe I can at least half use it for something other then using it to catch dust 🤷 And before you say reinstall it, etc.. Already tried  all the 101 of installation fixing..  

Hi, I believe that this might have been requested a few times… but probably not to the extent of a full explanation of how to implement the feature.I believe that for the sake of ease of use and customer satisfaction that when the [FN] or Hypershift key is held it will change to a defined chroma profile.The way in which this could be implemented is once the profile has been created the user can simply go into the profiles tab and select a Standard profile and Hypershift Profile for each game they wish tto use it for. The Hypershift profile will already be linked to the game by default as it already is, but the user would be able to select the “Chroma Studio” option in the list and then under the “Linked Games” section would be the option of choosing the “Hypershift Lighting Profile” as a dropdown list from the existing profiles. The default would be the same as the “Chroma Effect” selected. Once the user chooses a different option from the dropdown list it will force t

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

This current version of Synapse, specifically Chroma, is very slow. Has been for quite a few weeks now! Upwards of 12 Gb of RAM usage and still freezes. Also not getting lighting effects with Apex Legends. Still needs further testing. Probably try the current Beta. I need an update already! Thanks!

Apparently I’m not the only one with this problem... I bought new headphones for 200 usd, connected them to the PC and synapse, they were detected, but did not respond to the sound settings at all... Equalizer, loudness, noise isolation, and other settings do not affect the headset in any way . The sad thing is that such a small indie company as Razer cannot afford an adequate programming staff. I'm using Windows 11 24H2 latest build.

Razor Synapse 4 has a bug that's been bothering me for a long time. Synapse sometimes minimizes games to the desktop. This even happened to me mid-game in Black Ops 7. The only solution was to manually disable the Razor Elevation Service and the Razor Game Manager Service. One of these two services is causing games to minimize. The error did not occur again in Windows 10 after that.

Synapse 4 fails to detect the default audio device in Windows. Despite the correct headset, the BlackShark V2 Pro 2023, being selected in both Windows settings and the Control Panel, Synapse 4 repeatedly prompts to set the headset as the default device. As a result, none of the headset feature's function, the microphone, volume controls, or EQ settings work. Multiple attempts at reinstalling, restarting, and troubleshooting have not resolved the issue.Thanks. 

i got a viper ultimate mercury like last month and the software has been working fine until a few weeks up to a month ago, the mouse works fine but whenever i try to change the mouse settings in synapse it wont let me (macros, profile, overall wont let me change any of the mouse settings in app) how do i fix it?

I keep getting this error after installing Synapse 4 and trying to run it for the first time.I have tried many of the fixes I could find like disconnecting razer peripherals, using 7zip to unzip and then using the installer from the unzipped folder, run as administrator etc.Any ideas?  

Had v3.10 since November 2025 and they're are not showing but the previously saved Macros are still in the Razer folder. This used to work without issues. Do I have to reinstall?Tried simple troubleshooting such as: restarting razer synapse/razer services and rebooting PC. Same issue.

I downloaded razer synapse to uninstall a macro on my hunstman mini and everytime i open the application of synaspe it loads up shows me the log in screen then after a second it closes not giving me a chance to log in, without deleting the macro i cant use my keyboad because the macro is spamming keys which was placed by accident but now cant delete it. Any advice/help would be greatly appreciated.

For the last few days now every time I boot up my computer Razer Synapse 4 says that my local profiles don’t match the ones that are stored in the cloud. I note that the local settings are newer and I remember that I did recently make a small change so I choose to keep my local settings, but for some reason it doesn’t want to sync those settings to the cloud. I know that there’s a little spinning circle-type-thing that shows up in the corner whenever it syncs to the cloud but that shit never shows up anymore. I’ve tried to make small changes on all my devices in the hopes of that triggering a sync but nothing seems to want to work, so I’m asking here if any of you know of a way to sync profiles manually. I’ve looked through all the menus I could find in Synapse 4 but haven’t found anything but it’s possible that I could’ve just missed it. Based on the things I’ve read in the last few hours I suspect that there sadly isn’t a way to do this so I’m prepared for disappointment but I wan

I recently purchased a Deathstalker V2, and I was disappointed to see that Synapse for Mac does not include support for Deathstalker V2. Hoping this will be added soon.

So, I’m obviously not the first person to say this, which makes it even more infuriating, but Synapse 4 is the worst experience I’ve ever had with a software in my life. I don’t understand how a supposed “upgrade” to Synapse 3 is STILL a broken and buggy mess this long after it’s been launched, when Synapse 3 worked perfectly fine. If I could, I’d just stay with Synapse 3 indefinitely, but of course, Razer is forcing everyone to switch over within the next few months. I’ll just start with the main minor inconvenience I’ve dealt with: Synapse 4 takes absolutely forever to start up. So instead of seeing the custom profile that’s stored in my keyboards’ onboard memory, I see the generic ugly solid orange, green etc., until I fully log in and wait 10-15 seconds. This isn’t the end of the world, but definitely an annoyance, because with Synapse 3, it was pretty much instant and even started up when I was still on my computer’s log-in screen. What is even the point of having

Hello,I’m having an issue with my Razer Huntsman V3 Pro Mini.I created a profile where I set up some keys, as shown in the attached image, and then I saved it to the onboard memory. However, once I close Razer Synapse and reopen it, even directly, the activation mode turns on for all my keys automatically without me doing anything. I want to clarify that I haven’t pressed the Fn/Tab combination either. Sometimes, it happens the other way around: the activation mode turns off completely. The Rapid Trigger, however, remains unchanged. I even tried saving my profile to each slot in the onboard memory, but nothing works.Thank you in advance for your help!

I just downloaded Razer Synapse 4 and I’m trying to get it to recognize my Naga V2 Pro gaming mouse. I checked with Razer to see if the mouse is supported by Synapse 4 and it is. What do i need to do to make this happen inside S4? Howl do l program or configure the buttons? I’m sure that I’m missing something easy. Some directions that are simple to follow would be greatly appreciated!. I’ve been on this for two days now.Thanks!I created another. question earlier. I think this one is more clear.

I’m trying to program the buttons on my new Naga Pro. I’ve downloaded Synapse 4 from Razer and I’ve opened it and selected my device, but I am not seeing anyway to do this. I’m sure it’s something easy that I’ve missed. Could anyone please give me directions on how to do this? A simple explanation would be much appreciated!Thanks! 

Hey, Razer PLEASE add support for the DeathAdder essential mouse on Synapse for Mac Preview. Thanks!Love you!

In the Synapse Customize tab for the Naga V2 Pro, there are 4 pictures, 3 represent the 3 different side button panels you can have installed. The one currently installed has a green check mark, however if you change the panel out on the mouse the check mark does not move to the newly installed side panel, it stays on the one that was installed when Synapse started. You have to restart Synapse for it to recognize what side panel is installed. Razer Naga V2 Pro, Firmware Version 1.3.0.0 (latest) on the Mac Synapse 4 Preview Version 4.0.86.2504290730, on MacOs 15.5.

…. didn‘t support the Razer Naga Left Hand Edition? There are so many left-handed people! Many would surely love to use RNLH on their Macs. Please take this into account in the next update! Thank you in advance from a left-handed person who no longer wants to feel disadvantaged.
