Train Sim World 6: Constant Unreal Game Crashes Dovetail Support No Use (Workarounds)
Short answer
No confirmed fix yet. Players suggest: Fixes and Warranty: Intel released microcode updates (0x125, 0x129, 0x12B, and 0x12F) via BIOS updates to prevent further damage, but these cannot repair already degraded CPUs.
Why it happens
Your system may experience constant Unreal Engine crashes and failure to load past the main screen due to widespread instability and permanent hardware degradation affecting Intel 13th and 14th Generation desktop processors. A faulty microcode algorithm causes these CPUs to request excessive operating voltages, leading to irreversible hardware damage known as Vmin Shift. This results in random crashes, blue screens, and game failures, even after formatting your SSD, reinstalling Windows, updating graphics drivers, or upgrading your RAM.
How to fix it
- Update your motherboard BIOS to apply the latest Intel microcode updates (such as versions 0x125, 0x129, 0x12B, and 0x12F) designed to prevent further damage.
- Verify that all Intel-recommended settings are actively enabled inside your system BIOS.
- Run Intel's official testing utility to check the status of your processor.
If it still doesn't work
- Note that while microcode updates prevent further damage, they cannot repair a CPU that has already suffered permanent degradation.
- Test other Unreal Engine 4 based games on your system to see if the crashing behavior persists across different titles.
- Check your purchase history and contact your hardware retailer or manufacturer to pursue an Intel RMA (Return Merchandise Authorization) warranty claim if your CPU is permanently damaged.
What players reported
I run a 4090 i9 14th gen processor and for the bast few weeks ive had nothing but crashes wont load past the loading screen constant unreal crashes. I have bought 64gb on new ram thinking that could be it. Have completely formatted my SSD and reinstalled windows and a clean TSW with new GPU drivers. Still the same thing sometimes can get past the screen an play for hours. Other times not at all…
What players suggest
Hello OP, have you followed all the intel guidance concerning your intel 14th gen CPU? Intel 13th and 14th Generation desktop processors suffered from widespread instability and permanent degradation caused primarily by a faulty microcode algorithm requesting excessive operating voltages. This "Vmin Shift" issue led to irreversible hardware damage, manifesting as random crashes, blue screens…
Thank you so much for taken your time to explain this i appreciate it. I never knew about this at all and i am still within my actual warranty from when i purchased. I have already updated my bios and all intel recommended settings are on in the bios. So it looks like im going to have to go down the intel RMA route as i fear mine might be damaged. Again thanks for the heads up
You should have started with this... because this means, that your CPU is most likely not the culprit (and while it was somewhat low hanging fruit, it is not off the hook, "Raptor Lake" CPUs are prone to various issues - but if Intel's own testing utility has cleared your CPU, it should be OK for the time being). Anyway, if you own any other UE4 based game, now it is probably the good time to…
