Your Fortnite FPS tanked after the Chapter 7 update and you’re stuck playing a slideshow. Frame drops during build fights, stuttering every time you land at a POI, and your game hitching right when someone pushes you. Chapter 7 Season 1 (v39.50) brought a lot of new content, but it also brought performance problems that are hitting PCs across every hardware tier.
This isn’t your imagination. Epic switched rendering pipelines and added denser map geometry with the Chapter 7 overhaul, and the result is higher GPU and CPU load than previous chapters. Even players with RTX 4070s are reporting dips below 100 FPS in populated areas.
Here’s how to fix it — whether you’re on a budget laptop or a high-end rig.
Quick Fix
Try these three steps before anything else:
- Delete your shader cache: Navigate to
%localappdata%\FortniteGame\Saved\PipelineCaches\and delete everything inside that folder. Restart Fortnite. The first match will stutter briefly while shaders recompile, but subsequent matches will be smoother. - Cap your FPS to your monitor’s refresh rate (60, 144, or 165) in Fortnite settings under Display → Frame Rate Limit. Uncapped FPS causes GPU overshoot and inconsistent frame pacing.
- Update your GPU driver to NVIDIA 591.86 or AMD Adrenalin 25.1.1.
If those didn’t solve it, work through the full list below.
What Causes Low FPS and Stuttering in Fortnite Chapter 7?
Fortnite’s performance issues in Chapter 7 come from several sources:
- Shader compilation stutters — Every time the game encounters a new visual effect for the first time, it compiles a shader on-the-fly. This causes brief freezes, especially after updates that change visual assets.
- DirectX 12 overhead — Fortnite defaults to DX12, which adds CPU overhead for draw calls. On older CPUs (4 cores or fewer), this creates a bottleneck.
- Dense map geometry — Chapter 7’s map has significantly more objects, foliage, and lighting effects than Chapter 6. The same PC that ran Chapter 6 at 144 FPS might only hit 90-100 in Chapter 7.
- Background processes eating resources — Discord overlay, browser tabs, RGB software, and Windows Defender real-time scanning all compete for CPU time.
- Outdated drivers — NVIDIA’s Game Ready Driver 591.86 included specific optimizations for Fortnite Chapter 7. Running older drivers means you’re missing those gains.
- HAGS (Hardware-Accelerated GPU Scheduling) — Windows 11’s GPU scheduling feature can cause micro-stutters on some hardware configurations.
