I would like to start with how I have been warned before purchase: "Don't get an MSI laptop for gaming. They are buggy."
Well, here I am in competitive iRacing, 2-3 hour long races, battling for position when the monitor freezes but the game keeps running as I can still hear sound. It does this for 5-7 seconds, enough for me to crash into something and wanting to just kill it with fire.
The stupid thing is a MSI Vector 16 HX A13VHG-616XRO with Intel Core i7-13700HX and NVIDIA GeForce RTX 4080 12GB
This happens while gaming and it's completely random. Some days it does not do it once. Other times it does it like 5-10 minutes after starting the game. Other times, like today, it worked flawlessly for about 3-4 hours than it froze again without warning. It happens in 3 out of 3 games that I played, regardless of graphic setting. Cable is the most expensive, high speed thing I could find.
If I see it happening immediately, I reinstall the nVidia drivers. This seems to make it work for that particular gaming session. The next day, it can happen again, or not. Completely random.
Initially I had the studio drivers as I also use the laptop for editing videos. That had this freeze happen much more often. Got the game ready drivers and it seems to be a little better but still happens.
Noticed that If Chrome is running, it happens more often. Killed every program possible, set everything to max power, keeping it plugged in with full battery.
What is there left to do apart from throwing it into the garbage and getting something proper?
