I just took over a team that was using Git, and yes, I know it's everyones favourite VCS but for Games it's just about the worst thing available. I could measure art reviews with git in hours, now with perforce its seconds. I wish I was joking.

All the interesting tools that UE5 uses (Horde/UBA for a clean example) will require perforce.

but, Perforce hasn't done anything with its industry position. It's expensive as hell and they don't have operational costs related to hosting (you have to host it yourself, and honestly, for performance reasons you really want to- despite it being a real pain to maintain passed first install). There's some echoes of stuff they try but they have absolutely no solid direction and nearly everything they've been doing cuts against common sense or their userbase, while their core product keeps getting renamed but no actual improvements.

It's a lesson in how proprietary software is really a prison.

I wish I could use a better code review tool than Swarm.

I wish I could integrate SSO without weird LUA hooks which cause segfaults on my machine (enough of them causing a perforce deadlock).

and I wish I could run a distributed storage backend instead of relying on a big fat SSD and journalled backups that can't be restored because licenses are tied to the IP address of the main server.

It's forgotten technology, and the company that operates it is a zombie.
