Code Vein 2 Errors: Fix Paths, and When to Ask for a Refund
Every documented Code Vein 2 error, the fix order that works, and how to tell a fixable bug from one that merits a refund.
Last updated 2026-09-25 · evergreen reference
This page lists the errors Code Vein 2 actually throws on PC and the order to fix them in. Start with verification and drivers, then move to the engine-specific causes. The point is to get you to a working game quickly — but also to tell you when you are done: if you have worked through this list and the game still will not run, that is the point at which a refund request is reasonable, and you should include what you tried when you contact the store.
The errors and their fixes
Symptom, cause, and the fix that resolves it.
“UE Fatal Error” or “UE-CodeVein2 Fatal Error”
Cause: Unreal crashed before the game finished loading — during shader compilation, resource loading, or DirectX initialisation.
Fix: Verify game files, update drivers, run as administrator and remove any mods. Then force DirectX 11 with the -dx11 launch option, disable every overlay (Steam, Discord, GeForce, MSI Afterburner), raise the NVIDIA shader cache to 10GB or more, and — importantly — disable XMP or EXPO in BIOS, since memory overclocking is one of the most common triggers.
“Out of Video Memory” crash
Cause: Unreal Engine 5 frequently misreports deeper stability problems as video memory failure. On Intel 13th/14th-gen systems this is CPU voltage instability.
Fix: Update the motherboard BIOS for the Intel microcode fix, load Intel Default / Baseline settings, and turn off CPU overclocking. Also verify files, lower texture and shadow quality, disable motion blur, depth of field and screen-space effects, drop resolution if needed, do a clean driver install, and raise the Windows page file to 1.5× RAM initial and 3× RAM maximum.
Persistent stuttering
Cause: Unreal Engine 5 traversal and shader behaviour.
Fix: The widely used “Ultimate Engine Tweaks” mod edits Engine.ini at %localappdata%\CodeVein2\Saved\Config\Windows\Engine.ini for lower latency and fewer hitches; set the file read-only afterwards. Also enable Resizable BAR in BIOS and close background apps.
Cutscenes locked to 30 FPS
Cause: A framerate cap applied to cinematics in the shipping build.
Fix: An injectable ASI fix distributed via the PCGamingWiki forums removes the cap.
Crashes after a game or driver update
Cause: Mods and overlays losing compatibility.
Fix: Disable all mods first, then overlays. If the game becomes stable, re-enable them one at a time to find the culprit.
Fix order if you do not know which one you have
Cheapest and most reversible first.
1. Verify and restart
Verify game file integrity through your launcher and restart the PC. This clears stuck background tasks and driver hooks, and repairs the corrupt downloads that launch-day server load makes common.
2. Drivers, cleanly
Install the latest GPU driver from the vendor site rather than Windows Update, and choose the clean-install option. Both NVIDIA and AMD ship game-ready drivers for major releases that fix compatibility outright.
3. Strip overlays and background hooks
Disable Steam, Discord, Xbox Game Bar, GeForce Experience and MSI Afterburner overlays, along with RGB utilities and hardware monitors. These inject code into the game process and are one of the most frequent crash triggers.
4. Rebuild the shader cache
Clear the DirectX shader cache from Windows Disk Cleanup and delete the game’s own shader cache folder, then let it rebuild. Corrupted shader caches cause crashes that look like hardware faults.
5. Only then touch hardware settings
Remove GPU and CPU overclocks including RAM XMP/EXPO, check temperatures, and if the crash pattern points to CPU instability rather than the GPU, update the motherboard BIOS before assuming your hardware is faulty.
When to stop and request a refund
Drawing the line on unfixable problems.
Documented, acknowledged faults
If a fault is acknowledged by the developer as a known issue, say so in your refund request and include the crash pattern. Store refund windows are usually 14 days with under two hours of play, but documented technical faults that make a game unplayable are a valid reason to push past that — attach your crash logs and the steps you already tried.
What to include in the ticket
Include the full error text, when the problem began, whether it followed a patch or driver update, your hardware and driver versions, and the troubleshooting steps already attempted. A refund request with evidence is far more likely to be granted than one without.
