Stop Adobe After Effects Lagging: The Ultimate Fix Guide

There’s nothing more frustrating than pouring hours into a creative animation—only to watch your Adobe After Effects lagging crawl at two frames per second. Whether you’re working on motion graphics, compositing, or video titles, lag can kill your workflow and creativity.

Don’t worry—this guide will walk you through the most common reasons why After Effects lags, and more importantly, how to fix it. From optimizing your settings to repairing output video issues, we’ll make your editing experience buttery smooth again.

Part 1. Why is My After Effects Lagging

Lag in Adobe After Effects usually comes down to one simple truth: it’s a resource-hungry beast. The software demands a lot from your CPU, GPU, and RAM to render complex effects in real time. Here are the main culprits:

• High-resolution previews: Viewing at full resolution consumes tons of processing power.

• Too many background processes: Other programs (like Chrome or Discord) eat into your RAM.

• Cache overload: An overfilled disk cache can slow previews drastically.

• No multi-frame rendering: Without this enabled, AE can’t use all CPU cores efficiently.

In short, lagging doesn’t mean your project is broken. It just means AE is asking for more than your setup can currently deliver. The question on "how to fix after effects preview lag" is not such a big deal.

Part 2. How to Fix After Effects Lagging

Now that you know the reasons, let’s fix them one by one. These tips are practical, quick, and proven in dealing with how to fix after effects preview lag by professional editors.

Check if Your Hardware Reaches the Recommendation of After Effects

Before diving into settings, make sure your computer is strong enough to handle After Effects.

Here’s what Adobe recommends (and what actually works smoothly in 2025):

CPU: Intel i7 / AMD Ryzen 7 or higher

RAM: 32 GB or more (16 GB minimum)

GPU: At least 8 GB VRAM (NVIDIA RTX or AMD Radeon)

Storage: SSD with at least 100 GB free space

If you’re running AE on an older machine, consider upgrading your RAM or GPU. Even adding a small SSD cache drive can make a night-and-day difference.

Lower the Preview Resolution and FPS

After Effects Lagging Preview is often caused by viewing your composition at full quality.

To fix this:

Step 1. Go to the Preview Panel → change Resolution to Half or Quarter.

Step 2. Reduce the Frame Rate (e.g., from 60fps to 30fps) during previews.

This doesn’t affect your final render — it just makes previews lighter and smoother.

Pro tip: If you’re working on a complex scene, preview only a small portion of the composition by setting an In/Out range.

Enable Fast Draft Mode

Fast Draft Mode is your best friend for smoother previews without compromising too much quality. Simply click the Renderer dropdown and select Fast Draft.

It disables heavy effects like anti-aliasing or motion blur temporarily, and it reduces video noise automatically. This way, AE focuses on real-time responsiveness instead of trying to render every detail at once.

Enable Multi-Frame Rendering

Introduced in recent AE updates, Multi-Frame Rendering (MFR) lets After Effects use all available CPU cores — effectively rendering several frames simultaneously, addressing adobe after effects lagging.

To enable it:

Step 1. Go to Edit > Preferences > Memory & Performance.

Step 2. Check Enable Multi-Frame Rendering.

With MFR turned on, users often see up to 2x faster previews and renders. Combine this with Fast Draft mode and half-resolution playback, and your lag issues will drop dramatically.
