Synapse 4 is awful and it makes me want to completely leave the Razer ecosystem.

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 the onboard memory in the first place? Needing to have Synapse running to use my macros is one thing, I get that, but the lighting profile? Why? But again, that’s just a relatively minor inconvenience, and if that was the only problem I had, I’d get over it, but it’s clearly just scratching the surface. 

 

Onto the actual major issues I’ve been having in the short few weeks I’ve moved over: Sometimes my mouse just won’t work at all. I try taking out the battery and putting it back in, the light in my mouse wheel flashes like it turns on, but then it still doesn’t work. I try unplugging the USB dongle and replugging, same thing. Try turning off the switch on the bottom of the mouse and switching it back on, same thing. The only thing that works is completely restarting my PC (I suspect restarting Synapse itself would also work, but that’s kinda hard to do when I can’t use a mouse). And this is completely random. Sometimes it’s like that from when I start up my PC, sometimes it’s after multiple hours of use.

 

Another issue: Sometimes my lighting profiles just simply don’t work. I have two keyboards connected, and sometimes one of them will randomly go back to default patterns, sometimes both (despite again, having the profiles saved to the onboard memory of both). I go into Synapse to check what’s happening, it still SAYS it’s using my custom profile, but it simply isn’t. I have to toggle from “Quick Effects” back to “Advanced Effects” in the lighting tab, and sometimes that works, but not always, and in the case it doesn’t, I have to restart Synapse entirely to MAYBE get them to work correctly. It also seems to happen way more often on my mouse (which doesn’t have onboard memory), enough to the point where I just turned off the lighting on it entirely because it hardly ever used my actual custom profile and it was pissing me off. It’s a joke. It’s one of the main functions of the software, there’s no excuse for it being as broken as it is. Because, for the third time, I never had any of these issues with Synapse 3.

 

I like Razer products a lot, I clearly have multiple, two keyboards, a Blackwidow V3 and Hunstman Mini, and a mouse, a Basilisk V3 X Hyperspeed. I like the switches in the keyboards, and I like the ergonomics of the mouse. I even like the Chroma Studio software itself for making my lighting profiles, but Synapse 4 is genuinely making me never want to buy another Razer product again. It’s genuinely infuriating, especially because I remember trying to switch to 4 way back when it was still in beta and having the EXACT same problems. I chalked it up to the software being relatively new, figured the issues would be ironed out later, and just switched back to Synapse 3. And as I said, if I could just stay with 3 forever, I would without complaint. But now, Razer is FORCING us to switch to a software that is still broken. I’ve thought about getting rid of Synapse entirely and going to an open-source lighting software like OpenRGB, but I LIKE my lighting profiles and macros. I spent a lot of time making them and getting them to work the way I want, and I don’t want to switch to an entirely new software that doesn’t have the same functions and start from scratch. But it’s looking like that may be my only option until I get a new brand of keyboard. And I know I could also continue using 3 until it actually gets discontinued in January, but what’s the point? For 2.5 more months? That’s just putting off the problem that I will eventually run into again.

 

This software is such a joke, and the fact that so many people complain about it, but Razer has made no fixes, it’s incredibly disheartening. Listen to your customers, lest you lose them forever. I hold grudges against corporations, and I won’t forget this when I’m going to buy my next keyboard and mouse. Again, I like your products, but there’s absolutely no excuse for a software being the reason I want to switch brands. Rant over.

Sad but true.

They’re pushing the AI fad, but they’re not even using it this tools properly to help fixing their bugs xD 

Support ppl are great in closing cases, that’s all. They dont give f. about resolving the case. I think that they forgot about the shitstorm that they made about 2 months ago.

 

And the software … yeah - quality is degrading from release to release. I remember, that Synapse 4 in closed beta was ULTRA FAST, now when I’m running the Synapse it’ll take few secs to load all the stuff.

 


They should just make simple lightweighted software that control the most crucial thing, using pc to its full power with correct control of fans so it doesnt overheat. Maybe also single colour light of keyboard and thats it, nothing else. 

 

I dont have razor yet but as I read these stability problems I am not sure, that I ll buy this PC. Its just weird that I cant use all specs of this laptop without synapse. I dont need all that other crap. I dont even play games, just need stability, strenght and connecting multiple full hd displays. 

 

If somebody want other stuff, use second software for it. Having everything in one place is a bad idea, a lot of functions used makes this pc unusable, probabaly even when thrse functions r not even activated.

Im done now as of today. This new 4 software sucks. it messed up everything. i have overlay off i have booster off but it’s still doing it so f**k razer. i had the very first razer boomslang wheni was a kid and was always a fan. it was in japan too, an import so it cost way more than the US. Now i am done with razer. i just want simple software like the previous. This game booster and all telling me fps and temps in game, i have the disabled entirely but it is still telling me, on two different computers. I’m done.

I feel the same way. I don’t think Razer products are the issue, it’s their software and attitude towards customers. Have you watched what Synapse 4 does in the background? It’s responsible for more drive activity than my antivirus software. Razer don’t explain what game manager does — nor let you disable it.

I came here looking for a solution to a Windows problem that I thought might be caused by Synapse 4 (text in menus aren’t visible in Dark mode) but have become disheartened by the multitude of ignored support requests. Razer community on Reddit is even worse.

The problem is there is nowhere to go. All peripheral software is either equally buggy, or functionally limited.
