If Fortnite began stuttering or losing frames after the Chapter 3 Season 2 update, that timing is useful—but it does not establish that the update caused the problem. Epic has documented a DirectX 12 shader-compilation issue that can cause heavy stuttering, along with several system and settings checks. Work through the steps below to narrow down the cause before considering hardware changes.
First, identify what “FPS drops” means on your PC
A consistently low frame rate, a brief hitch when a scene changes, a freeze, and a black screen are different symptoms. Note which one you see, when it happens, and whether the issue began only after an update. Also check whether other games are affected and, on a laptop or multi-GPU PC, whether Fortnite is using the dedicated graphics processor.
Hitches are not necessarily evidence of a faulty graphics card: Epic’s technical performance guidance notes that asset loading and scene complexity can contribute to them. The symptom alone does not identify a cause.
Try Epic’s DirectX 12 shader-cache fix
Epic Games says Fortnite can sometimes repeatedly recompile DirectX shaders in DX12, resulting in heavy stuttering. Its support article describes this as a possible cause—not proof that every post-update frame drop has the same explanation.

“Sometimes the Fortnite client will try to repeatedly recompile DirectX shaders without stopping, which results in heavy stuttering while playing on DirectX 12 rendering mode.”
Epic’s recommended troubleshooting step is to close Fortnite and the Epic Games Launcher, then clear the relevant shader-cache files using the instructions in its DirectX 12 stuttering support article. Follow the article’s current steps rather than deleting unrelated files.
Clearing the cache is not an instant or guaranteed fix. Epic warns that the first match afterward may still stutter while Fortnite rebuilds its shaders. Give that process a chance to complete before judging whether performance has changed.
Check drivers, graphics selection, and system conditions
Epic’s graphics troubleshooting guidance recommends checks that apply to particular problems and setups; they are not a promise that each step will resolve FPS drops.

- Update the graphics driver. Epic recommends checking for driver updates when troubleshooting graphics problems. Use the update channel for your GPU and restart if the installer or system requests it.
- Confirm Fortnite is using the high-performance GPU. On a laptop or PC with integrated and dedicated graphics, check the system’s graphics settings or GPU control panel. Selecting the dedicated GPU can matter if the game was assigned to the integrated processor.
- Check ventilation if performance worsens during a long session. Epic advises checking airflow and dust when issues appear after extended play. This is a system-condition check, not evidence by itself that overheating is occurring.
- Consider Performance Mode for specific DX12 failures. Epic lists trying Performance Mode for certain DX12 crashes, freezes, or black-screen issues. That advice is symptom-specific; it does not establish that Performance Mode is always faster or the right fix for ordinary frame drops.
Change one relevant setting at a time and restart the game when needed. That makes it easier to tell whether a change affected the symptom instead of combining several changes and guessing.
Compare rendering modes on the same PC
If Fortnite offers an alternate rendering mode on your system, compare it with DX12 under similar conditions: use the same scene and graphics settings, and pay attention to frame-time consistency as well as average FPS. Also track crashes, freezes, black screens, visual quality, and whether the dedicated GPU is in use. A mode that produces a higher average but frequent hitches may not feel better to play.
There is no current benchmark in the cited guidance that establishes a universal winner for your hardware. Microsoft’s 2020 DirectX 12 and Fortnite discussion explained that DX12 can distribute rendering work across multiple CPU cores. In its specific Fortnite comparison, Microsoft reported DX12 average frame rates 2% higher than DX11. That historical result describes Microsoft’s comparison at the time; it is not a current benchmark or a prediction for an individual PC.

The reported timing may help you decide when to investigate, but the available official material does not establish that the Chapter 3 Season 2 update caused these FPS drops. It also does not establish a reliable figure for how many players were affected, so the issue should not be described as a confirmed widespread regression.

Epic later announced that DX12 became the default rendering mode on PCs with certain higher-end GPUs, while describing Performance Mode separately. That announcement provides later context about Fortnite’s rendering options; it does not explain what happened on a particular PC during Chapter 3 Season 2.
When to keep troubleshooting—and when not to buy hardware
Use the symptom and the results of each check to choose the next step. If clearing the cache changes first-match stuttering but not sustained low FPS, those may be separate issues. If the problem occurs across multiple games, investigate the broader driver or system conditions rather than treating Fortnite’s update timing as a diagnosis.
The information in this report does not identify a failed component or establish that an upgrade is needed. Start with the cache, driver, GPU-selection, settings, and airflow checks that fit your symptoms; a hardware purchase is not a supported default fix.
