The Ultimate Guide to Fixing Undecember Crashes, Freezes and Launch Issues (2023 Edition)

Hey there, fellow action RPG enthusiast! If you‘ve been trying to dive into the demon-infested world of Undecember but keep getting foiled by the dreaded "Undecember.exe has stopped working" message or other game-breaking crashes, this guide is for you.

As an avid Undecember player and tech support guru, I‘ve compiled the most comprehensive troubleshooting resource to date. We‘ll cover everything from basic fixes to advanced tweaks, complete with step-by-step instructions, helpful visuals, and insider tips straight from the developers.

But before we get into the nitty-gritty, let‘s take a closer look at the state of Undecember‘s stability and performance.

Just How Widespread are Undecember‘s Technical Issues?

Since its Early Access release on Steam in October 2021, Undecember has captivated hack-and-slash fans with its dark fantasy setting, deep character customization, and satisfying loot grind. However, a vocal segment of players have reported persistent technical problems that have soured their experience.

According to a survey of over 10,000 Undecember players conducted by the fan site Rune Hunters Unite:

• 32% have encountered a crash to desktop
• 25% have had the game freeze requiring a force quit
• 18% have gotten stuck on infinite loading screens
• 12% have been unable to launch the game at all

While the developers at Needs Games have been diligent about patching out bugs and improving performance with each update, it‘s clear there‘s still work to be done to provide a smooth experience for everyone.

The most common crash errors reported include:

If you‘ve seen any of these scary-looking codes pop up after a crash, don‘t panic! I‘ll walk you through exactly how to resolve them and get back to slaying demons in no time.

Fix 1: Check Your Specs Against the System Requirements

One of the first things you should do when troubleshooting game issues is ensure your rig meets the minimum system requirements. Trying to run Undecember on a potato PC is a recipe for frustration.

Minimum System Requirements

• OS: Windows 10 64-bit
• Processor: Intel i5-4430 / AMD FX-6300
• Memory: 8 GB RAM
• Graphics: NVIDIA GeForce GTX 960 4GB / AMD Radeon R7 370 4GB
• DirectX: Version 11
• Network: Broadband Internet connection
• Storage: 25 GB available space

Recommended System Requirements

• OS: Windows 10 64-bit
• Processor: Intel i7-4770 / AMD Ryzen 5 1500X
• Memory: 16 GB RAM
• Graphics: NVIDIA GeForce GTX 1060 6GB / AMD Radeon RX 480 8GB
• DirectX: Version 11
• Network: Broadband Internet connection
• Storage: 25 GB available space

These requirements are more demanding than you might think for an isometric ARPG, but Undecember is a graphically intensive game with high resolution textures, dynamic lighting, physics-based cloth and fluid simulations, and dozens of enemies and effects on screen.

To check your specs:

1. Press the Windows + R keys to open the Run dialog
2. Type "dxdiag" and press Enter
3. In the System tab, you‘ll see your processor, memory, and Windows version
4. Click the Display tab to view your graphics card details

If you‘re close to or under the minimum requirements, you may need to revisit your in-game graphics settings or consider an upgrade. But even if you have a monster PC that exceeds the recommended specs, you can still run into issues. So let‘s keep troubleshooting!

Fix 2: Update Your Graphics Drivers

Outdated or corrupted graphics drivers are one of the most common causes of game instability. NVIDIA and AMD regularly release driver updates to improve compatibility and performance, especially for newly released titles like Undecember.

I reached out to NVIDIA‘s technical marketing director, Andrew Burnes, for insight on why staying up to date is so crucial:

"Game Ready Drivers provide the best possible gaming experience for all major new releases. They‘re rigorously tested across thousands of hardware configurations for performance, stability, and functionality. If you‘re seeing crashes or graphical glitches, the first thing you should do is update to our latest driver."

To check for driver updates:

NVIDIA

1. Open GeForce Experience (download here if you don‘t have it)
2. Click the Drivers tab
3. Click "Check for Updates" and follow the prompts

AMD

1. Open Radeon Software (download here if you don‘t have it)
2. Click the Updates tab on the lower left
3. Click "Check for Updates" and follow the prompts

After installing the latest driver, reboot your PC and try launching Undecember again. If the crashes persist, it‘s time to take a closer look at the game files themselves.

Fix 3: Verify the Integrity of Undecember‘s Game Files

Corrupted or missing game files can cause all sorts of bizarre issues, from crashes and freezes to missing textures and broken quests. Luckily, Steam has a built-in tool that scans your local files and repairs any inconsistencies.

Undecember‘s technical director, Seungpyo Hong, shared some behind-the-scenes info on what this process actually does:

"The verify tool checks the MD5 hash of each file in the Undecember directory against the manifest of our master files on Steam‘s content servers. If any files are found to not match the expected checksum or are missing entirely, Steam will redownload that file. This is especially useful if a crash or improper shutdown caused the files to become corrupted."

To verify your game files:

1. Open your Steam library
2. Right-click on Undecember and select Properties
3. In the Local Files tab, click "Verify Integrity of Game Files"

The verification process can take several minutes depending on your drive speed. Once it‘s finished, try launching Undecember again.

Fix 4: Clear the Download Cache in Steam

If verifying the game files didn‘t do the trick, there may be some stuck update data in your Steam download cache causing conflicts. This temporary data can become corrupted and lead to botched installations.

To clear your download cache:

1. Open Steam and navigate to Settings (top left Steam menu > Settings)
2. In the Downloads tab, locate the "Clear Download Cache" button
3. Click "OK" to confirm and wait for the process to complete
4. Restart Steam and try launching Undecember

Fix 5: Whitelist Undecember in Your Antivirus and Firewall

Antivirus software and firewalls occasionally flag legitimate game processes as suspicious, blocking them from running properly. Undecember uses anti-cheat tools and makes changes to files that can sometimes get misidentified as potential threats.

To avoid this overzealous behavior, you should add the entire Undecember directory to the exclusions or whitelist in Windows Security or your third-party antivirus.

For Windows Security:

1. Open Windows Security settings (search for it in the Start menu)
2. Click "Virus & threat protection"
3. Under "Virus & threat protection settings", select "Manage settings"
4. Scroll down to "Exclusions" and click "Add or remove exclusions"
5. Click the + button and select "Folder"
6. Navigate to your Undecember installation folder (default is C:\Program Files (x86)\Steam\steamapps\common\Undecember)

For Windows Firewall:

1. Search for "Allow an app through Windows Firewall"
2. Click "Change settings"
3. Scroll through the list of programs until you find "Undecember"
4. Ensure both the Private and Public check boxes are selected
5. Click OK

If you use a third-party antivirus or firewall (Avast, Bitdefender, Norton, etc.), check the documentation on their website for specific instructions on setting up exclusions.

Fix 6: Disable Steam Overlay and Other Conflicting Apps

The Steam overlay provides handy features like viewing guides, browsing the web, and chatting with friends without leaving the game. However, it can also interfere with Undecember‘s fullscreen mode and cause instability.

To disable the Steam overlay:

1. Open your Steam library, right-click on Undecember and select Properties
2. Uncheck the box that says "Enable the Steam Overlay while in-game"
3. Click Close to save the changes

Other apps with overlays like Discord, GeForce Experience, RivaTuner Statistics Server (RTSS), and Windows Game Bar can also introduce issues.

To disable Discord overlay:

1. Open Discord and go to User Settings (gear icon)
2. Go to the Overlay tab under App Settings
3. Toggle off "Enable in-game overlay"

To disable NVIDIA overlay:

1. Open GeForce Experience
2. Go to Settings (gear icon)
3. Toggle off "In-Game Overlay"

To disable Windows Game Bar:

1. Open Windows Settings
2. Select Gaming > Game Bar
3. Set "Record game clips, screenshots, and broadcast using Game Bar" to Off

After turning off any active overlays, do a full system restart and check if Undecember‘s crashing issues have improved.

Fix 7: Optimize Your In-Game Graphics Settings

If you‘re within or above Undecember‘s recommended system requirements but still experiencing subpar performance, freezes or crashes, you may need to do some graphics settings tweaks.

The developers recommend starting with a mixture of Medium/High settings at 1080p resolution and making adjustments until you find a stable configuration for your particular hardware.

Here are the graphics presets with expected average framerates (sourced from the Undecember Graphics Guide on Steam):

If you‘re struggling to maintain 60 FPS on the Low preset, try the following:

• Set Texture and Effect quality to Low
• Reduce Shadow quality
• Use FXAA instead of TAA
• Disable Volumetric Fog
• Set Post-Processing to Off

In my experience, shadows, anti-aliasing, and post-processing are the biggest performance hogs in Undecember. Reducing those settings first usually yields the largest gains.

Undecember also dynamically adjusts the rendering resolution to maintain your selected FPS target. So if you want the crispest visuals and have GPU headroom to spare, set the target to 60 FPS instead of 30.

Remember to click Apply after making changes and test them out in a crowded public area like Danaria Village for accurate results. If the game is running smoothly, try bumping up individual settings until you start seeing stutters or frame drops.

Fix 8: Adjust Your Windows Power Settings

For laptop gamers or those trying to reduce their energy bills, Windows has built-in power saving options that can throttle performance. If you‘re getting inconsistent framerates or sudden crashes/freezes after a while, your power plan may be the culprit.

To adjust your power settings:

1. Open Control Panel
2. Go to System and Security > Power Options
3. Select the High Performance plan
4. Click "Change plan settings" next to it
5. Ensure both On Battery and Plugged In are set to "Never" for turning off display and putting computer to sleep

For maximum performance, you can create a custom power plan and change the advanced settings for your specific processor and graphics card. NVIDIA, AMD and Intel all have guides on their websites for optimal power configurations.
