I started playing first person shooters again last year. Player Unknown's Battleground. It takes a beast of a PC to play.

Other players I play with online are always talking about upgrades and saving up for a complete new system with all the latest hardware.

So I think fortnite and PUBG have definitely driven some growth in Gaming PC sales/hardware sales. Also the popularity of youtubers and streamers are driving kids and teens to ask for gaming PCs too.

Now that PUBG is on Xbox there is a new influx of players who started playing it on console but wanted to move over to the PC version.

Shooters on PC are much better than playing on a console, plus you usually get the features, updates and new maps first. But the feel of playing with a mouse and keyboard is way better on PC. Console ones are fun but I much prefer playing on a PC.

PUBG does require very high specs, but afaik fortnite has much lower requirements (owing to a competent development team, fewer polygons, and smaller textures) and will run on any potato. Haven't actually played either, but that's the impression I've gotten; I don't think people are rushing out to buy pcs for fortnite.
