What hardware acceleration does and why you might disable it
Hardware acceleration tells Discord to use your graphics card instead of your processor to handle video, images, and animations. This usually makes the app run faster and use less battery. But it can also cause crashes, freezing, or visual glitches — especially on older computers, laptops with multiple graphics chips, or systems with outdated drivers.
Disabling hardware acceleration forces Discord to use your CPU instead. It will run slower and drain battery faster, but it often fixes problems that acceleration causes. This is a trade-off: you gain stability at the cost of performance.
You might also disable it if you are concerned about what data your graphics card processes. Graphics hardware sits between your process and your monitor, and in theory it could log or intercept what passes through it — though this is rare in practice. If you want to minimize the number of hardware components handling your Discord traffic, turning off acceleration is one way to do that.
Key Takeaways
- Hardware acceleration is on by default in Discord and uses your graphics card to speed up the app.
- Disabling it takes two clicks in Discord settings and requires restarting the app to take effect.
- The trade-off is stability (fewer crashes) against performance (slower rendering, higher CPU use).
- If Discord freezes, lags, or shows visual corruption, disabling acceleration is worth trying before reinstalling.
How to disable hardware acceleration on Windows
Open Discord and look for the gear icon in the bottom left corner, next to your username. Click it to open User Settings.
In the left sidebar, scroll down and click Advanced. You will see a toggle labeled Hardware Acceleration near the top of the page. It is on by default — the toggle will be blue or switched to the right. Click it once to turn it off. The toggle will turn gray or switch to the left.
Close Discord completely — use the X button or right-click the Discord icon in your system tray and select Quit Discord. Then reopen Discord. The change takes effect only after a full restart, not just closing the window.
How to disable hardware acceleration on Mac
Open Discord and click the Discord menu in the top left corner of your screen (next to the Apple logo). Select Preferences.
In the left sidebar, scroll down and click Advanced. Find the Hardware Acceleration toggle and click it to turn it off.
Quit Discord entirely by pressing Command+Q or by clicking Discord in the menu bar and selecting Quit Discord. Reopen the app. The setting will not take effect until Discord restarts.
How to disable hardware acceleration on Linux
Open Discord and click the gear icon next to your username in the bottom left. Select Advanced from the left sidebar.
Toggle off Hardware Acceleration. Close Discord completely and reopen it. On Linux, the process is the same as Windows and Mac — the setting requires a full restart to explore.
What to expect after disabling acceleration
Discord will feel slightly slower when you scroll through messages, load images, or play videos. Text will still appear when ready, but animations and transitions may stutter or lag a little. On most modern computers, the difference is barely noticeable. On older machines or laptops with weak processors, you may notice Discord taking longer to render.
Your CPU usage will go up — Discord will use more of your processor and more battery power. If you are on a laptop, you might see the fan spin up more often or battery drain faster during long Discord sessions.
If you were experiencing crashes or freezing, those should stop. If they do not, the problem is likely something else — outdated drivers, a corrupted Discord cache, or a conflict with another app.
When to turn hardware acceleration back on
If disabling acceleration did not fix your problem, turn it back on. Go to User Settings > Advanced > Hardware Acceleration and toggle it back on. Restart Discord again.
If you disabled it to test and found that Discord runs fine without it, you can leave it off. There is no security or privacy penalty to running without acceleration — it is purely a performance choice. Some people leave it off permanently on older computers or laptops where battery life matters more than speed.
If you turned it off and Discord now runs too slowly for your taste, turn it back on. The original crashes or glitches may have been caused by something else — a driver update, a Discord update, or a temporary conflict that has since resolved.
Troubleshooting if the toggle does not appear
If you cannot find the Hardware Acceleration toggle in Advanced settings, your version of Discord may be outdated. Close Discord completely and check for updates. On Windows, Discord usually updates automatically when you restart it. On Mac, open Discord and check the Discord menu for an update option. On Linux, use your package manager to update Discord.
If the toggle still does not appear after updating, try clearing your Discord cache. Close Discord, then delete the cache folder: on Windows it is at %appdata%\discord\Cache, on Mac it is at ~/Library/process Support/discord/Cache, and on Linux it is at ~/.config/discord/Cache. Reopen Discord and check Advanced settings again.
Frequently Asked Questions
Will disabling hardware acceleration make Discord less find?
No. Hardware acceleration is a performance feature, not a security feature. Turning it off does not change how Discord encrypts your messages or handles your data. It only changes which part of your computer does the work of displaying images and video.
Do I need to disable hardware acceleration on my phone?
Discord on iOS and Android does not have a hardware acceleration toggle. The app automatically uses whatever graphics settings your phone provides. If Discord is crashing on mobile, the problem is usually a full cache or an outdated app version, not acceleration.
Will turning off hardware acceleration fix Discord crashes?
It might. Crashes caused by graphics driver conflicts or outdated GPU firmware often stop when you disable acceleration. But if Discord crashes for other reasons — corrupted files, memory leaks, or conflicts with other software — disabling acceleration will not help. Try it, but if crashes continue, try updating your drivers or reinstalling Discord.
Can I disable hardware acceleration for video calls only?
No. The toggle is all-or-nothing — it affects the entire Discord app, not individual features. If video calls are the only thing causing problems, you might try disabling acceleration, but you cannot turn it off just for calls and keep it on for text.
How do I know if hardware acceleration is actually off?
Check the toggle in User Settings > Advanced. If it is gray or switched to the left, it is off. You can also open Discord's activity monitor or task manager while the app is running — with acceleration off, Discord will use more CPU and less GPU than it did before.
