Razer Blade 15 – random FPS drops during games, bottleneck maybe?

Hey everyone,

I’ve been using my Razer Blade 15 (i7 + RTX 3060 + 16GB RAM) for a while now. Lately I’m getting random FPS drops while gaming — even on medium settings. Temps are not crazy (75–80 °C) and I already updated drivers and Windows.

Sometimes GPU usage stays low while CPU goes high, and I’m wondering if this could be some kind of bottleneck issue between CPU and GPU, or if it’s just Synapse / Windows causing the lag.

Has anyone else with a Razer laptop experienced this? Any tips to stabilize performance would be great.

Thanks!

This does sound like a CPU-side bottleneck or power management issue rather than raw GPU performance. On Razer Blade laptops, random FPS drops are often caused by aggressive CPU power limits, background Synapse profiles, or Windows power cpu bottleneck calculator settings forcing the CPU to throttle briefly. Try setting Windows and Synapse to High Performance, disable CPU boost temporarily to test stability, and check if the CPU is hitting PL1/PL2 limits even at normal temps. Also monitor per-core CPU usage, as one overloaded core can cause drops even if overall temps look fine. Many users report smoother FPS after limiting background services and tweaking power behavior rather than changing graphics settings.

Sounds like classic laptop power/throttling behavior rather than an actual hardware bottleneck. When the GPU usage drops but CPU spikes, it’s cara download scribd​ usually the CPU hitting power or boost limits for a moment, which causes those random FPS dips. Setting Windows + Synapse to High Performance and cutting background apps typically smooths things out a lot.

I’ve seen similar issues while testing gaming setups and small performance tweaks often make a bigger difference than lowering graphics settings. Documenting these fixes has even helped me while writing tech breakdowns on my blog — little optimizations go a long way.
