That nasty security hole that Intel is dealing with right now is coming into effect on the gaming side of things, in Epic Games' smash hit Fortnite.
Epic has said that Fortnite servers are heavily reliant on cloud services, with the latest CPU patches to affected Intel CPUs (here's a list) are causing all sorts of issues. Epic writes: "We wanted to provide a bit more context for the most recent login issues and service instability. All of our cloud services are affected by updates required to mitigate the Meltdown vulnerability. We heavily rely on cloud services to run our back-end and we may experience further service issues due to ongoing updates".
The developer also added: "Unexpected issues may occur with our services over the next week as the cloud services we use are updated. We are working with our cloud service providers to prevent further issues and will do everything we can to mitigate and resolve any issues that arise as quickly as possible. Thank you all for understanding. Follow our Twitter @FortniteGame for any future updates regarding this issue".
