Lowering the GPU Power Limit slider can reduce performance
Power Limit is a control in GPU tuning software that caps the graphics card’s power budget. If set too low, the card may be unable to sustain its boost clocks, reducing performance.
- When to check
- Check it when GPU performance is unexpectedly low, especially after applying a quiet preset or an old tuning profile.
- Where to find it
- MSI Afterburner: Power Limit in the main window. AMD Adrenalin: Performance → Tuning → Custom/Manual → Power Tuning.
- What stock means
- Usually 100% in Afterburner. Adrenalin typically shows an offset: 0% is stock, and negative values reduce the limit.
- Why not maximize it
- Restore stock only if an unintended limit caused the slowdown. Deliberate limits can trade performance for efficiency or less noise; GPU-heavy games are more affected than CPU-limited ones.
