💡 General Tip: Experimenting with resolution can help find your perfect balance. Lowering resolution increases FPS but may increase CPU bottleneck.

Estimated FPS at 1080p (high)

Ranges, not exact figures - identical builds vary by roughly a quarter in real use depending on drivers, thermals and background load.

Method: estimated from measured GPU baseline framerates and PassMark CPU scores, capped by whichever component limits first. Workload factors derived from the OpenML "fps-in-video-games" dataset (CC-BY, Sven Peeters).

Intel Core i5-10400F @ 2.90GHz + GeForce GTX 1660 SUPER — FPS by game and resolution

High preset. Each cell is a range; the label marks which component sets the ceiling. Blank cells mean this pairing has no measured data for that combination — nothing is estimated in.

How quality settings affect this build — Fortnite at 1080p

Dropping settings only helps while the GPU is the limit. Once the label reads CPU, lowering quality stops buying frames on this pairing.

Preset	Estimated FPS	Limited by
Low	170–283 FPS	GPU
Medium	162–271 FPS	GPU
High	134–223 FPS	GPU
Max	95–158 FPS	GPU

Bottleneck by resolution

Raising resolution shifts load from the CPU to the GPU, so the balance of this pairing changes with the display it drives. Note this measures imbalance, not speed — the lowest figure is usually the lowest resolution, which is not the one to play at. Read it alongside the limiting part.

Smallest imbalance 1280x720 9.5% bottleneck · CPU-limited

Largest imbalance 7680x4620 18.8% bottleneck · GPU-limited
