একজন গেমার তৈরি করেছেন যিনি অনুমান করতে ক্লান্ত হয়ে গিয়েছিলেন

The night the game kept stuttering

I still remember the match. My frames kept dipping right when a fight broke out, and my aim paid the price. On paper my PC looked strong — a solid graphics card, a decent processor, plenty of RAM. So why did it choke?

I did what most gamers do. I checked my drivers, my temperatures, my settings, even my internet. Everything looked fine. That's when I realized the problem might be balance, not raw power. One part was holding the rest back, and I had no easy way to prove it.

Why the existing tools let me down

I tried every bottleneck calculator I could find. Most of them only compared a CPU and a GPU, spat out a vague percentage, and left me with more questions than answers. None of them looked at my RAM, my storage, my resolution, or what I actually used the PC for. None of them told me what to fix first.

As someone who upgrades rigs on stream, I knew that wasn't good enough. Gamers deserve a straight answer before spending hundreds on the wrong part.

So I built the tool I wanted

I teamed up with developers who love hardware as much as I do, and we built the Bottleneck PC Calculator from the ground up. The goal was simple: give any gamer a clear, honest read on their system in seconds. Not a mystery number — a real breakdown of what's limiting performance and how to fix it.

Today the calculator checks six factors — CPU, GPU, RAM, storage, resolution, and use case — and returns a bottleneck percentage, a balance score, an FPS estimate, and a ranked upgrade list. It's free, it works on any device, and it's the tool I wish I'd had that stuttering night.

Beyond the calculator

A balanced PC is only half of a great setup. On the Bottleneck PC Calculator blog, our team shares hands-on gaming guides, including the best gaming mouse picks, the best gaming chairs for long sessions, and the best gaming keyboards for a competitive edge.
