A MaximusFPS guide
Why does my FPS suddenly drop or stutter?
Sudden FPS drops usually mean something changed during play: a heavier scene, asset or shader work, background activity, memory pressure or reduced hardware clocks. The useful clue is what happens at the same moment as the drop. A repeatable capture is more informative than a long list of general performance tweaks.
What to check first
- Does it happen in one game, all games, or only after the PC warms up?
- Watch temperatures, clocks, GPU load and memory use alongside frametimes.
- Note recent game, driver, Windows or hardware changes.
Likely causes and how to distinguish them
A first visit to a map can involve loading and shader work. A repeat run may behave differently, so do not compare a cold first run with a warmed-up second run and call that an optimization gain.
Sustained drops after several minutes can indicate heat or power limits. A spike when switching apps may instead reflect background work or memory pressure. Total CPU utilisation can hide a busy game thread.
Online pauses can be network-related even when the game keeps rendering. Use ping and packet-loss indicators alongside local performance data.
Diagnostic steps, in order
- Restart the game and repeat a short route with unchanged settings. Record when the drop occurs and whether it repeats on later runs.
- Pause downloads and test without nonessential recording or overlays, one at a time. Keep protection active and avoid indiscriminate service removal.
- If load is consistently GPU-heavy, lower a relevant graphics setting. If clocks fall as temperatures rise, inspect cooling and manufacturer limits.
- Verify game files through the official launcher when only one game misbehaves. Check that game’s developer guidance before clearing caches or changing its renderer.
Limitations and when help may be appropriate
Software tuning can help some background-load or configuration problems, but cannot fix an overheating fan, failing storage or every game patch regression. Seek help when measurements are unclear, crashes accompany stutters, or hardware symptoms appear. Preserve the baseline rather than changing everything at once.
Follow-up questions
Should I clear every cache?
No. Clearing a shader cache can temporarily add compilation work and is best reserved for a documented problem. Follow the specific game’s guidance.
Does more RAM always fix stuttering?
Only if capacity or memory behaviour is part of the bottleneck. Check actual usage and paging symptoms first; a larger kit does not fix every slow frame.
