The first big expansion for Monster Hunter World, Iceborne, is finally available on the PC. However, the game’s latest update brought major performance issues to both the main game and its expansion. And from the looks of it, these PC performance issues are mainly due to the new anti-cheat system that Capcom has implemented.
In case you weren’t aware of, Monster Hunter World is currently maxing out most CPUs. According to numerous reports, the culprit behind this unusual CPU behaviour is the new anti-cheat system. Now the good news here is that there is a workaround for these “optimization” issues that you can use right now in order to improve overall performance.
All you have to do is follow this guide:
- Start the game and wait until you’re in the main menu
- Press alt+enter to switch to windowed mode from fullscreen
- Press ‘X’ to close the window
- When asked if you really wanna close the game, say ‘no’ (people have been saying to leave this box open, but it doesn’t seem necessary, so just say ‘no’ to close it)
- Press alt+enter again to switch from windowed back to fullscreen
Now the reason this workaround fix works is because it tricks the anti cheat to terminate the process. Numerous PC gamers have reported lower CPU usage and higher framerates after using this fix. Therefore, we suggest using it if you are currently experiencing any performance issues.
Capcom has stated that it’s currently investigating these PC performance issues. As such, it will be interesting to see whether the Japanese company will “optimize” its anti-cheat solution via a new title update.
Stay tuned for more!

Thanks, Capcom! /s
Crapcom being Crapcom and people still throw money at them. Smh…
I agree
It’s almost as if minor annoyances don’t outweigh hundreds of hours of fun gameplay…
Cheat anti cheat software! Genous!
The irony.
HAhahaha
Why is this article referring to anti-cheat as DRM?
These two are NOT the same things.
isn’t anylonger, if it was
Imagine how “secure” their DRM is that it can get tricked by such a childish method which got discovered fast and made public instantly.
And there are people who get paid to make this.
They are Japanese it’s expected. What do you expect from a Japanase company?
Clearly expecting a minimal level of competence is a mistake.
can you give me the full picture of ur profile pic? @adnanvoktur:disqus look very nice https://media0.giphy.com/media/iJa6kOfJ3qN7a/giphy.gif
Childish?? I still cant forget how one my friend beat windows 2000 password protection screen… With Alt+f4!
You could get admin access to Windows XP home by just logging in in safemode.
Honestly, why inst Steams VAC good enough? It works and bans are permanent. Shouldn’t need anything else beyond VAC.
Sloppy work by Capcom.
It’s one of these “workarounds” who work their best if you are imagining improvements really, really hard.
Conversely, it doesn’t do absolutely sh*t for me.
Not that I was having particular problems to begin with, but still: absolutely NO difference in performances whatsoever.
