Short answer: SSD won't increase your FPS in most games. But it WILL eliminate texture pop-in, reduce loading screens by 5-10x, and prevent stuttering during streaming open worlds.
Where SSDs Help (Massively)
- ›Loading screens: 80% faster on SSD
- ›Open-world streaming (Cyberpunk, GTA V): zero pop-in
- ›Game launch time: 3-4x faster
- ›Asset hitching: completely eliminated
- ›DirectStorage games (Forspoken, Ratchet & Clank): can't run without NVMe
Where SSDs Don't Help (FPS-wise)
Once a game's assets are loaded into RAM and VRAM, the CPU and GPU are doing all the work. Storage speed is irrelevant at that point. So your FPS during a CS2 match won't change between SSD and HDD.
NVMe vs SATA SSD?
For games not using DirectStorage, the difference between a SATA SSD and an NVMe is small (typically 10-20% on loading times). Save your money and put it toward more RAM or a better GPU.
