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.

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.be/upGhuFuAIDo?t=17, 0:17 - 0:52 https://youtu.be/v0vHE1ooHDc?t=57, 0:57 - 1:25After completing these steps, log in to your profile in Razer Synapse. It will load the previous settings from your profile and download and install all the necessary modules, jus

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:  

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. Synapse 4 – Tartarus Pro 8-Wege-Steuerung Problem (weiterhin un

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.

I’ve been dealing with a Razer Synapse 4 issue affecting the Tartarus Pro for over 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.This is not a minor issue. It represents a clear functional regression.The currently suggested workaround (switching to 4-way input) is not a viable solution, as it significantly limits the usability of the device to the point where it is no longer usable for its intended purpose.At the same time, there is no option to return to Synapse 3, as it has been discontinued.This issue has not only been observed by me, but has also been reported multiple times across the community.At this stage, the question is no longer whether the issue exists — but:Is this a known, unresolved problem —or a deliberate change in functionality within Synapse 4?Given the repeated community reports, a clear and transparent statement from Razer would

After updating to Razer Synapse 4, my internet connection started dropping for ~30 seconds approximately once per hour. Other devices on the same router (Wi-Fi) worked fine during the drops, confirming the issue is on the PC side.After extensive diagnostics using Windows event logs, I identified the root cause:The following Razer services spam the Windows network stack with hundreds of "hostname changed" events every minute, which eventually causes the connection to drop:- Razer Chroma SDK Server- Razer Chroma SDK Service- Razer Chroma Stream Server- Razer Game Manager Service 3EVIDENCE:With Razer services running (April 23, 2026):Windows event log Microsoft-Windows-NetworkProfile/Operational showed dozens of Event ID 4004 firing every single minute — hundreds per hour, all with "hostname changed: true".With Razer services stopped (April 26-27, 2026):Only ~40 events over two full days, all corresponding to normal PC boot cycles. Zero unexplained network disturbances.Confirmed disconnec

When i try to upload on workshop Chroma effects it dosent upload it works on profile  and macro but not uploads i dont know if its on my side or if its the s4’s problemDid razer stop doing razer chroma effects fixes?I try to find more Chroma effects profiles but its none. Does none buy v4 (Yes i know the switch problem but still)Edit: Tried even with a brand new chroma profile dident work still. Restarted the program also i did.

I’ve already sent this to support but I thought I’ll put this here too.This is an issue I have only on Synapse4.Basically, when ever I cycle keymap(I use 1 as main and 2 for some obscure shortcuts) and use it, Synapse can randomly overwrite the 2nd keymap with the mapping of 1st’s.Here’s a video of me reproducing this issue by spamming keys while cycling, but this has happened multiple times when I’m using Tautarus normally and I don’t spam keys.My temporary solution for this is to dupe the preset so I can switch to it when it happens, delete the original and dupe the dupe for next time...

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): https://youtu.be/9Bn-Bn-WMZkIn both videos, the same macro profile was used; the only difference is whether Synapse 4 was running or not. The behavior suggests that Synapse 4 intercepts or throttles hardware macros, inserting a forced minimum delay.This was not present in Synapse 3, and represents a performance downgrade that affe

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 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! 

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?
