MikroTik router causing high ping spikes during online gaming — how to stabilize connection?

Just following up on this in case anyone has experience optimizing MikroTik routers for online gaming.

I've been experimenting with a few settings since posting, including queue configurations and bandwidth prioritization, but I'm still seeing occasional ping spikes during longer gaming sessions. The issue isn't constant, which makes it a bit harder to diagnose. I'm particularly interested in whether QoS rules, FastTrack settings, or specific firewall configurations could be affecting latency-sensitive traffic.

Part of the reason I'm looking into this is that I regularly test different online and mobile games across my network to evaluate connection stability. For example, while checking updates and multiplayer-related discussions surrounding Stick War Legacy Mod APK on stickwarmods, I noticed how even small latency fluctuations can impact the overall gameplay experience, especially in games that rely on real-time synchronization. Although Stick War Legacy and competitive shooters have different networking requirements, the importance of a stable connection is something they share.

If anyone has successfully configured a MikroTik router for gaming and managed to reduce ping spikes or packet loss, I'd appreciate hearing what settings or best practices worked for you.

What have you done so far?
Are you familiar with the term bufferbloat?
There are a couple of topics, perhaps you can read i.e.: Fq_codel/ cake with fasttrack - update

Best forum can do is to have a 2nd look to your config, for optimization purposes.

But since there is no config, what are you trying to achieve and what is your thought logic? What do you think it will happen next?

Maybe yes, maybe no. Without config, we cant see…

How can you prove it's not a problem with the game server, the internet provider, or the console/computer you're using?

Have you tried unplugging EVERYTHING and leaving ONLY the console/computer connected directly via cable?

You use Wi-Fi for gaming?

Perhaps you get help, only to discover later that the wasted hours were for nothing because the problem lies elsewhere.
