Synapse 4 is still a buggy mess
I was stupid, I upgraded to Synapse 4 and... I WAS STUPID.
Damn, the software doesn't work at all. I have 16 Razer devices, my entire PC (excluding the processor, graphics card, and RAM) is Razer.
I absolutely need Synapse, otherwise my entire setup just stops working.
Chroma keeps desynchronizing, Synapse takes 10-15 minutes to start and, more importantly, load, AND AFTER A FEW HOURS, IT CRASHES. I have to kill the software in Task Manager and wait again for the "Loading" messages in its infernal tabs to disappear. It's annoying.
Without it, my switch between Leviathan and Kitty no longer works. My Tartarus profiles managed by Hypershift no longer work.
Please Razer, fix this quickly, because having DESTROYED Synapse at the same time as Nvidia killing GeForce Experiance for GeForce App is a mockery beyond words...
100% Agree with you here the software needs rewritten from the ground up.
Far too many bugs.
And to add to it 3 is getting discontinued in the future as well.
What happens to all the devices that need to use Synapse 3-
E.G. Kraken v3
Which hates synapse 4.
i dont use synapse 4 cause it has less functions for my camera than synapse 3.
That’s strange… What camera are you using? Did you’ve submitted this bug to Razer Support?
Razer Support is useless. Earlier in this thread I mentioned the issues my Kraken V3 Pro had with THX profiles - they requested all sorts of extra information that wouldn’t help them fix the issue in any way, such as my address, serial number, phone number, etc.
You're lucky that they were at least pretending to have a conversation with you. I was just sent to a forum by technical support to figure out my own problems. They said that synapse 3 would no longer be supported because it was unsafe, and recommended switching to synapse 4. It's stable and secure, right.
I also wrote to them about my global keys not being saved. I told them that it worked fine in synapse 3. But in synapse 4 the global keys refuse to be saved in the program.
They answered me:

Great report from Gamers Nexus on Razer hardware, Synapse and support.

Thanks for the videos. I have 2 faulty Blackwidows V4 Pro keyboards with yellow switches. Right from the start i have had problems with both of them. On one i experienced a rattle in the spacebar and on the other one the shift key was stuck. Now after 4-5 months they started with double typing en then the RGB underneath of some of the keys fals out, yes on both of them! My Razer Raptor 165hz have problems with backlight bleeding, also right from the start. Also Synapse 4 is a huge problem. I can't use it and switched back to Synapse 3 with the annoying upgrade banner. The only thing i can give Razer credit for is the Basilisk en the glass mouspads, but i will never buy anything from them. For now i bought myself 2 Gravastar Pro 75% keyboards and this is the best thing i have ever done.

Glad someone pointed this. I don’t expect any bigger changes inside, just hope that they’ll at least fix the annoying bugs in Synapse 4 (and there’s a lot of things to fix unfortunately, and the developement/bugfixing is ultra slow).
I’ve already mentioned it few months ago, but no one listens to an insignificant fish (and more important - the customers) xD

This is for their hardware what about the software?
Not enough.
Switching lighting profiles causes devices to move in Studio. Their answer hit refresh. So I'm waiting 2+ minutes for my 21 devices to settle to make changes. Switch profiles and go through it all again. Oh no, my headphones weren't on. So in every lighting profile it has now moved every device because new devices go to the center. Instead of the next available slot. Synapse 3 no problem even loads things in quicker.
Tartarus v2 can't be put on large format RGB mousepads in Studio. I can do keyboard and mouse. Two mice but not this keyboard? Timing is wrong because that's not where I have it in real life. Oh switch to signal or whatever. No they conflict with the Corsair fan system I have. I chose Razer for RGB and Corsair fan software in 2019. 2020 through now everything worked. I built another PC with the same idea and it's screwed in Synapse 4 and I have Freyja that requires 4.
Doesn't really matter as the whole system will not be synced after a while. Chroma shows everything is fine but the lights are still playing something from 10+ minutes ago.
Chroma ARGB controller still not displaying Studio effects on startup. Must toggle brightness off and on. Improvements made but I have reported this all year. Once a month. Also told me several months ago 26 led fans would be added. No option for this with three fans. 26x3 is 78. Device supports 80 a port. I'm getting that was a lie just so I don't submit another ticket. 60+ just this year.
Can't have more than one of the same device. Chroma ARGB controller for example. I have two identical Lian Li TL series fan hubs they use Serial Numbers to identify the seperate devices. Add one device setup with the software. Unplug. Setup second device. Shut down. Add first back all good. Does not work with Razer. In fact all tabs closed work on one controller and the second tab shows up and you are editing both now. Why?
Adding new devices causes existing devices to be moved. Why can't they go to next available?
Changing lighting profiles with Aether strips added causes devices to scramble. Changing lighting profiles with wireless ARG controller added causes devices to scramble.
Changed the way THX works. I hate it.
Huntsman Elite keyboard I got in a giveaway in 2018 barely ever used. I play with Tartarus v2. Delete key spams so fast only in Synapse 4 it makes the key unusable. They suggested it was a hardware problem. If I close Synapse 4 the key works just fine.
Tartarus v2. Games see this as a controller making it next to impossible to switch to controller. Even Razers wolverine v3 pro. I've been through 5 of theses since 2017. Buy, Warranty Repair. Buy, warranty, repair. Tartarus v2 pro made it past warranty. 2 months later needed repaired.
Clio if you turn down the volume on the device then try to raise it in Synapse it only goes up to what the device is set to. Or it did and now only does it at volume 0. Currently trying to kill the battery as there is no reset on this device. Hopefully that fixes something.
Clio is a joke. $250 and the $80 Leviathan v2x a USB powered device has more volume. Website says use as part of your 7.1 setup. Can't even add center. Windows shows stereo, quadrophonic and 5.1 yet the software has no option. Quadrophonic seems to be the one to use. Games are a lot quiter and it's pointless with the lack of volume. Oh, sorry we were talking about software…
All of these issues have been reported. Some more than once. I'm probably forgetting stuff too. It feels like if it's not the newest tech you don't matter. Even then Clio is significantly louder before adding to Synapse and doing the firmware update.
Now everything I say is being reviewed before posting. Love it! Shut me up any way possible.
So - it’s been 2 months. Has Synapse 4 improved at all since, or is it still a burning garbage pile?
Stile pile of garbage. And not only that, because of focusing on Mac version, the development of Windows version slowed down to a snail pace.
+1Stile pile of garbage. And not only that, because of focusing on Mac version, the development of Windows version slowed down to a snail pace.
Not only development.
Synapse 4 overall slowed down to a snail pace. Loading times are horrendous.

Indeed. It’s now slower than Synapse 3, which is truly an astonishing achievement.
I had to switch to synapse 4 since blackwidow v4 low profile is not supported by synapse 3 and my profile switching is not working properly anymore … tried fresh install, deleted all synapse 3 files and registry entries, but no luck. please fix synapse 4
Beta name was removed, but beta quality was not. Give it more months to cook.
It’s relatively simple to make synapse cleaner and less bloated. Just refer how Wooting does their utility software, users can literally just customize and change their settings via Web Browser. Other than that users can update their peripherals firmware WITHOUT a software. Razer needs to go back to their drawing board imo. Oh last but not least, RAZER should definitely review their scroll wheel encoder of their mouse, its absolutely balls.

There aren’t many good things to say about Synapse, but it not requiring an internet connection to use it is one of them.
Updating firmware also hard requires software, as firmware is software and a device cannot just magically say “hmm, I’m gonna update myself to fix some bugs” without having some form of internet connection and firmware management software.
The issue with scroll wheels on mice isn’t specific to Razer mice. Every manufacturer has scroll wheel issues, because it’s the most mechanically complex and fragile piece of a mouse, with the unfortunate bonus of being in a position prone to receiving external shock.
We’re all disappointed in Razer here - but making poor comparisons and incorrect statements isn’t going to help anyone.

Define which part of my statement that is incorrect.

Your claim that updating firmware "hard requires software" is factually outdated. The method is called DFU (Device Firmware Update) over HID, and it's a universal standard. A device can present itself as a simple USB drive or a standard input device to receive a firmware file. This is how many brands, including Wooting, Keychron, ZSA (Moonlander/Planck), and even some Glorious and Asus devices, handle updates. You can literally search up these update processes on YouTube, its that simple.
-
The internet connection point is a red herring. The core issue is software bloat and system residency. Synapse isn't just an update tool; it's a constantly running suite that consumes resources, can conflict with other software, and requires creating an account. A browser-based DFU update is a transient, one-time action. It respects the user's system and choice. This is the standard Razer is failing to meet. Respectfully, Razer has all sorts of devices/peripherals, so maybe a “one that fits all” software would be ideal for THEM, but for the consumers, its not.
-
Regarding the scroll wheel: While it's true all scroll wheels can fail, the failure rate and nature of the failure are what users critique. Razer mice are frequently reported to suffer from the "scroll wheel encoder" issue, which results in erratic scrolling or registering scrolls in the wrong direction. I personally encounter this issue, I had to solder a new encoder myself. This isn't just about physical shock; it's often a matter of component quality and design. Brands using higher-grade optical encoders (like some from Logitech) demonstrably have fewer reports of this specific issue.
I apologize if what I stated was not clear cut enough, but everyone is living in the 21st century, 2.6 billion of the world’s population has no internet which is roughly ~30% of the global population, if you can afford Razer’s products, it is safe to say that you definitely can afford fibre/data/roaming/hotspot.
