If you're like me—a gamer who still loves those PS4 gems—then PS5 Game Boost Mode is a total game-changer. Seriously, it’s not just marketing fluff. Sony quietly packed some serious tech magic into the PS5 that lets older games run *better* than they ever did on their original hardware. Let’s break down how it works, what you gain, and which titles benefit most.

What Is Game Boost Mode?
Game Boost is a PS5 feature that automatically enhances backward-compatible PS4 games. Unlike PS5 enhanced titles with official patches (like Ghost of Tsushima Director’s Cut), Game Boost works on unpatched games by giving them access to more CPU and GPU power. No dev update needed. Just pop in your old disc or download, and boom—smoother frame rates, faster loading, and better stability.
How Does It Actually Work?
The PS5 allocates extra system resources dynamically. While PS4 games aren’t remastered, they often suffer from performance issues—like frame drops or stuttering—due to hardware limits. Game Boost pushes the clock speeds higher and uses the SSD to cut load times by up to 60% in some cases. According to Digital Foundry tests, over 100+ PS4 games see measurable improvements.
Real-World Performance Gains
Here’s a look at how some popular titles perform with Game Boost enabled:
| Game | Original Target FPS (PS4) | Average FPS (PS5) | Load Time Reduction |
|---|---|---|---|
| Spider-Man (2018) | 30 | 58–60 | ~55% |
| God of War (2018) | 30 | Stable 30 | ~60% |
| Horizon Zero Dawn | 30 | Stable 30+ | ~50% |
| Red Dead Redemption 2 | 30 | More consistent frames | ~45% |
Notice something? Even games locked at 30fps feel smoother because the engine runs more efficiently. Input lag drops, physics respond faster, and fast travel becomes way less of a chore.
Limitations to Know
Not every game gets a massive upgrade. Some, like Final Fantasy VII Remake, were already optimized tightly for PS4 Pro and don’t scale as well. Also, resolution doesn’t typically increase unless the game has a performance mode that dynamically upscales.
Should You Use It?
Yes—especially if you replay story-heavy games. The PS5’s Game Boost unlocks hidden potential in your existing library. No extra cost, no downloads. Just pure, free performance juice.
Bottom line: If you’ve held onto your PS4 collection, now’s the time to revisit them on PS5. You might be shocked how good Uncharted 4 feels with near-instant loading and buttery combat.
