FAQ
What exactly is the Root-Cause Report?
A one-time purchase that unlocks one analysis completely — and permanently. You get every stutter investigated with its cause and our confidence in it, your throttle causes named and ranked, the session time-split, the premium AI write-up, a PDF you keep, and a share link that never expires. There is no subscription and nothing expires.
Which report does my purchase unlock?
If you buy from a report page, that exact report. If you buy from here, it applies to your most recent completed analysis — and if you have not run one yet, it waits and unlocks the next one you run.
Can I cancel anytime?
Yes. Cancel Pro anytime from your profile — no questions asked, and you keep access until the end of your billing period. A Root-Cause Report has no subscription to cancel; you own it either way.
What payment methods do you accept?
We accept all major credit cards, PayPal, and Apple Pay through our payment partner Paddle.
Do I need to install anything?
No. Everything works in your browser. Just upload your HWiNFO log files.
What does Free actually give me?
A real answer, not a teaser: your health score, every finding we detect, the measured CPU-vs-GPU frame split, how big your worst stutter was and how many you had, and whether you are being throttled. What Free withholds is the attribution — which cause, at which minute, with what confidence — and that is what a paid report unlocks.
Why not just use a free monitoring tool?
Tools like HWiNFO, CapFrameX and the NVIDIA overlay capture the data — they do not interpret it. None of them tells you which of your sensors caused which stutter. That interpretation is the whole product here.
