Recent changes are often the clue
A driver change, BIOS change, GPU move, monitor change, or game update gives the first best branch.
Why your PC has low FPS or stutter
This page is for the moment when a game or workload suddenly feels worse after a build, driver change, upgrade, or settings change. The goal is to separate true performance loss from stutter, frame pacing, heat, background load, and display-setting mistakes before chasing the wrong bottleneck.
Low average FPS and stutter are not always the same problem
One can point to expectations or settings, while the other can point to heat, background load, or frame pacing.
One measured comparison beats random tuning
Checking scope, temperatures, and one known workload usually helps more than changing five settings at once.
Keep the performance check focused
- Notice whether the problem started after a driver update, hardware change, or display-setting change.
- Compare one known workload with the rest of the system instead of assuming the whole PC slowed down.
- Check temperatures, clocks, and obvious background activity before chasing new hardware.
- Confirm display resolution, refresh rate, sync mode, and any frame-limit changes if the symptom appeared after monitor or settings work.
Open the page that matches the performance pattern
Start with thermals if heat climbs fast. Start with build-target pages if the real question is whether the hardware fits the job.
