Razer Synapse

Hi everyone,I recently contacted Razer Support regarding an issue with Razer Synapse 4 crashing a few seconds after launch (case handled by Rex from support). I was informed that the team is aware of the problem and currently working on a fix that will be released in an upcoming update.I just wanted to ask if anyone else here is experiencing the same issue, and if there are any updates or temporary workarounds that have helped.Thanks in advance for any info or suggestions!

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’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. 

After update to Synapse 4, Blackwidow Elite Media Keys RGB are not fully light up. When I exit from Synapse, media keys RGB are fully light up again.  Synapse 4 Active: Synapse 4 disabled:  Please help.

Hello to all When i first used My Razer Basilisk V3 i installed Chroma RGB app and Synaps 3...Going into Chroma RGB i could simply  select the RGB effect and change  the speed or colours …I never had Razer updates or anything it was awesome… i reinstall windows  and Chroma RGB app and Synaps 4..I opened the   Chroma RGB app the simple settings are gone i now have to use the Chroma RGB Studio app..Even after following the tutorial video i can’t get the effect  to work why Razer made things worse i don’t know..Can i get the older version of Chroma RGB APP back ?? because i rather go back to the very easy simple settings Of  the older chroma RGB app and i do not want to be forced to use studio….

I have the viper v3 pro and haven't played faceit in 2 months for context. When playing cs2 normally my sensitivity is completely fine and the usual however when I try to play Faceit and turn on their anti cheat software it drastically lowers my sensitivity. I've tried to change my sens in game then change it back to no avail. Is there a solution to this? The only time it sometimes works is when I reinstall synapse however reinstalling the software every time i want to play faceit is annoying.

My C:\Windows\Installer\Razer? is over 13GB. I’ve read from others that it can be unsafe to delete this. Is there a good way to reclaim this space? Is it actually safe to delete? 

I have purchased the Razer Freyja haptic gaming cushion and am trying to use for Sim racing. I have Simhub but cant see the Freyja when I try and add a new device. I have it connected, on and have the Razer Synapse app aswell. No idea how to connect it.

Hello,I’m using Razer Synapse 4.0.86 and Razer Chroma 4.0.63. I have Deathadder V2, Firefly V2 and Ornata Chroma. I have a strange (and annoying) behaviour, every time the system reboots automatically (for example to apply Windows Update patches, after a blue screen, ecc….) the Chroma lights on every Razer device are off before the login. After I login to the machine, the lights turn on after a while when the user profile starts loading. This does not happen if I manually reboot the system, the lights are on even before the login.Anyone else with the same issue ?It seems something is not restored correctly before the user log in.

I am currently with Synapse 4 (recently). Since that: some games seems to trigger the chroma apps as intended, but other mysteriously don’t. They are all green switched to be enable.For exemple [apps that work]: Dredge and Hogwarts (Steam), Diablo IV (Blizzard), Journey to a Savage Planet (Epic) and Cyberpunk (GOG Galaxy) are working as intended. I did need to start a few time with Hogwarts and Cyberpunk, but now it is working without failing.BUT, with Alan Wake 2 (Epic) or Silent Hill 2 (Steam), it does not work. The game apps is listed and activated with the slider-switch but nothing change when I launch either software.*** I have tested the issue also by creating a Chroma profile for the game (illuminating with a spoof color just to see), this profile was correctly activated with the game’s launch. So, it CAN detect the launching of the software. At present moment, I have unlinked this chroma profile. *** Did someone find a solution to this issu

Hello everyone, first time razer customer here. I picked up a Tatarus V2 after seeing some people online talk about how great it works for video editing (my profession).  I got really excited about it, but was sad to see that it isn’t supported in the synapse for max preview yet. My question is: is it planned to ever be supported on synapse for Mac? Will products as old as the Tartarus be included in this new software? Or should I just return the Tartarus to Best Buy Thanks 

Hello, could you please tell me if support for the THX Competitive mode is planned for the game Arena Breakout: Infinite?

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..  

Just bought a Blackshark V3 headset and wanted to test out the THX Game Profiles for Battlefield 6. They posted on Razer official facebook page that it was added in October 2nd. I can’t activate it. I checked several posts on reddit and V3 owners have the same issue while the older headphones are working fine with the THX profile. This is false advertising and I want to ask ,what are you waiting for RAZER TO ADD IT FOR YOUR NEW HEADSETS!!! THEY WON’T FIX UNTIL ENOUGH PEOPLE COMPLAIN ON SOCIAL MEDIA. What incompetence!! 

Synapse for Mac is relentlessly opening the system settings, prompting me to grant it permissions that it has absolutely no business asking for.I’m using a mouse with no RGB lighting, so Screen & System Audio Recording is unnecessary. Full Disk Access? Seriously? That’s a huge ask for an app that adjusts my mouse sensitivity. I don’t even need Bluetooth access, because this mouse has a dongle. It’s one thing to ask, but when the app is open, it constantly pops open the dialog asking for these things, and if you focus the window, it will open the related pages in the system settings. It’s extremely intrusive.
