MH4U seemingly random bluescreen

Enter a description of your issue here, in full detail.
This is the third time my pc goes bluescreen while playing MH4U, and it happen at random occasion but only in village
(if it happen only on heavy map, or fighting monster, I would just take that my device is too much of a potato, but every time this happen it’s in the village. Last time it happens in Harth, close the bottom right part of the village)

cheats I used are performance tweaks, I agree that I might need to update my driver, I just want to report this in case someone else experienced the same thing.
I’ll try to do more test

Here’s some issues I found with your log that might help.

  • You are running out of date drivers for your GPU. You need to install the most recent driver for your graphics card from Intel’s website.
  • The CPU Clock percentage is not 100%. You may experience unexpected game speed.
  • You have cheats enabled. This might cause weird behaviour or crashes. Please disable them and retest if your game is experiencing bugs or crashes.

update: I just checked my drivers in intel’s website’s scanner thingy, it said all my driver are up to date except for bluetooth and wi-fi

Latest drivers for HD 5500 ends in 5171 while yours only 4568. Grab the latest here:

You might need to install manually through zip: and follow this guide:

Core_CPUClockPercentage: 80

You should set this back to 100%, otherwise emulation will be unstable.

Got it, I’ll try.
Sadly it will be difficult to discern whether it works or not.
I’ll just try it and comeback after a week if the bluescreen stop occurring

Update: it works, I haven’t experienced any bluescreen so far. Thankyou for your help
