Gamers chasing lower latency encounter a lot of advice ranging from genuinely effective to essentially placebo — separating the two matters before spending money on a fix.
Network routing — the actual path your data takes to a game server — is the most common real cause of latency that's fixable without new hardware. Your ISP's default routing isn't always the fastest available path, and this is specifically what route-optimization tools address by finding a genuinely faster path to the same server.
They analyze multiple possible network paths to a game's servers and route your traffic through whichever path currently has the lowest latency — this is a real, measurable technical mechanism, not a marketing claim, though the benefit varies by your specific ISP and location relative to the game's servers.
Software claiming to "boost" your internet speed or CPU performance for gaming, absent an actual specific bottleneck it's addressing, is generally not doing anything a network route optimization tool or basic hardware upgrade wouldn't already cover — general "gaming optimizer" software with vague performance claims deserves skepticism.
Run a traceroute to your game's servers during actual lag to see where delay is occurring — if it's clearly in network routing rather than your local hardware, a route optimization tool addresses the actual cause. If the bottleneck is local hardware, no routing tool will fix it.
