Echoes of Aincrad Slow Motion Bug: How to Fix Low FPS and Speed Issues on PC
When I first launched Echoes of Aincrad, I expected smooth anime-style combat with flashy Sword Skills and fast-paced boss encounters. Instead, after about twenty minutes of exploring Aincrad, something felt completely wrong. The game wasn’t simply dropping frames—it was behaving as if someone had switched on permanent slow motion.
My character walked slower, attack animations became painfully sluggish, enemies reacted like they were underwater, and every battle lost its excitement. At first, I assumed my PC was overheating or that my graphics driver had somehow become corrupted. But after testing multiple systems, reading through community discussions, and experimenting with Unreal Engine settings, I realized the problem is much more specific than a normal FPS issue.
If you’re dealing with the same bug, don’t worry. In most cases, it’s completely fixable without waiting for a game update.
This Isn’t a Typical Low FPS Problem
One thing that confused me initially was that the game wasn’t always reporting terrible performance.
Sometimes the FPS counter looked acceptable, yet the gameplay still felt incredibly slow. That’s because Echoes of Aincrad appears to tie certain gameplay systems to frame pacing and engine timing rather than relying purely on independent physics simulation.
When those timings become unstable, the entire game slows down instead of just rendering fewer frames.
That means you’ll notice things like:
- Characters moving slower than normal
- Combat animations taking much longer
- Enemies reacting with noticeable delay
- Camera movement feeling heavy
- Menus becoming less responsive
In my experience, this almost always happened after entering larger environments or effects-heavy battles.
Why It Happens
Although the developers haven’t officially explained the issue, it behaves very similarly to several other recent Unreal Engine 5 releases.
The engine seems to struggle whenever frame pacing becomes inconsistent. Interestingly, both extremely low frame rates and extremely high frame rates can trigger the same behavior.
If your GPU suddenly becomes overloaded—or your CPU cannot keep up with all the visual effects—the game’s internal timing begins drifting away from its intended update cycle.
Instead of producing brief stutters, the entire simulation starts slowing down.
Ironically, having a powerful graphics card doesn’t always prevent this. I tested the game on multiple hardware configurations and noticed that even newer systems can experience the bug under the right circumstances.
The Biggest Fix: Cap the Game at 60 FPS
This was easily the most effective solution.
Like many PC players, I originally left the frame rate option set to Unlimited because I use a high-refresh monitor.
That turned out to be a mistake.
After limiting the game to 60 FPS, nearly every slow-motion issue disappeared.
To do this:
- Open the game’s graphics settings.
- Find the Frame Rate option.
- Select 60 FPS instead of Unlimited.
- Enable VSync.
- Restart the game completely.
If the built-in limiter doesn’t behave correctly, forcing a 60 FPS cap through your GPU control panel usually works even better.
It may sound strange to intentionally reduce performance, but stable frame pacing is far more important than chasing the highest possible FPS in this particular game.
Make Sure Windows Uses Your Dedicated GPU
This issue especially affects gaming laptops.
Windows occasionally decides that a demanding game should launch using integrated graphics instead of your dedicated GPU. The result is immediate performance loss and, in this case, the infamous slow-motion effect.
Check Windows Graphics Settings and manually assign Echoes of Aincrad to High Performance mode.
It only takes a minute and can completely eliminate unnecessary bottlenecks.
Some Graphics Settings Hurt More Than They Help
The visuals are impressive, but several graphics options demand a surprising amount of processing power while offering only subtle visual improvements.
I personally recommend turning down the following first:
- Ray Tracing
- Motion Blur
- Ambient Occlusion
- Film Grain
These settings create a heavier workload without dramatically changing gameplay.
If you’re also using upscaling, try switching from Quality mode to Balanced or Performance.
The visual difference is smaller than many people expect, while performance can improve significantly.
Mouse Input Can Actually Make Things Worse
This surprised me more than anything else.
The mouse controls sometimes feel unusually floaty, almost like the game is trying to imitate controller movement.
After disabling camera assistance options, the overall responsiveness improved noticeably.
I recommend turning off:
- Camera Follow
- Camera Correction
If you already own an Xbox or PlayStation controller, it’s worth testing the game with it.
Personally, I found combat considerably smoother using a controller than with a high-polling gaming mouse.
Clean GPU Drivers Can Solve Hidden Problems
If none of the in-game tweaks help, don’t overlook your graphics drivers.
Driver updates installed over older versions occasionally leave behind shader cache or configuration issues that only appear in specific games.
A completely clean installation often resolves strange Unreal Engine behavior.
The process is straightforward:
- Download the latest driver for your graphics card.
- Use Display Driver Uninstaller (DDU) in Safe Mode.
- Remove the old driver completely.
- Install the newest driver from scratch.
- Let the game rebuild its shader cache after launching.
It takes a little longer than a standard update, but it’s often worth the effort.
Recommended Settings
| Setting | Recommended Value | Why It Helps |
|---|---|---|
| Frame Rate | 60 FPS | Keeps engine timing stable. |
| VSync | Enabled | Improves frame pacing. |
| Ray Tracing | Disabled | Reduces GPU workload. |
| Motion Blur | Off | Produces a cleaner image while improving performance. |
| Camera Follow | Off | Prevents awkward camera behavior. |
| Graphics Mode | High Performance | Ensures the dedicated GPU is always used. |
Other Things Worth Checking
If you’re still experiencing slow-motion gameplay after trying the major fixes, there are a few additional things I’d recommend checking.
- Verify your game files through Steam. Corrupted or incomplete files occasionally cause unexpected behavior after launch-day patches.
- Close unnecessary background software. RGB utilities, browser tabs, overlays, recording applications, and hardware monitoring tools can sometimes interfere with Unreal Engine games more than expected.
- Allow shaders to finish compiling. The first launch after updating drivers or installing the game may feel rough while new shaders are generated.
- Restart after changing graphics settings. Some Unreal Engine options don’t fully apply until the game has been restarted.

My Overall Experience
After spending several hours experimenting with different combinations of settings, I found that this isn’t really a hardware problem.
Instead, it’s an optimization issue caused by how Echoes of Aincrad handles frame pacing and engine synchronization.
Once I locked the game to 60 FPS, disabled unnecessary graphical features, ensured Windows was using my dedicated GPU, and turned off the camera assistance options, the difference was immediate.
Combat felt responsive again, dodges registered correctly, Sword Skills activated without delay, and exploration became enjoyable instead of frustrating.
Hopefully Bandai Namco improves the engine behavior in future patches, because modern PCs should be perfectly capable of running the game well beyond 60 FPS without affecting gameplay speed. Until then, stability is much more valuable than raw frame numbers.

Final Thoughts
The slow-motion bug in Echoes of Aincrad can easily make you think your PC isn’t powerful enough, but that’s usually not the real issue. In my experience, it’s almost always tied to unstable frame pacing, Unreal Engine timing, or an unfortunate combination of graphics settings.
If I had to recommend only three fixes, they would be:
- Lock the game to 60 FPS.
- Force Windows to use your dedicated graphics card.
- Disable Ray Tracing and camera assistance features.
Those changes solved the problem on every system I tested and transformed the experience from frustrating to genuinely enjoyable. Hopefully future updates make these workarounds unnecessary, but until then they’re the quickest way to get back to exploring Aincrad without feeling like every battle is happening in slow motion.
