What Does “Guaranteed CPU” Mean?

TL;DR:

Your Foundry VTT world deserves to run smoothly — even on busy Friday nights. With Guaranteed CPU, your server always has its own share of computing power reserved, so your games stay playable no matter how crowded our servers get.

Why We Introduced Guaranteed CPU

When you’re hosting a Foundry VTT game, there’s nothing worse than lag, long module load times, or a map taking ages to render right when combat starts. We’ve been there ourselves — and we know that smooth performance can make or break your session.

That’s why we introduced Guaranteed CPU. It ensures that every server we host always gets a minimum amount of CPU power that it never has to share. Even if everyone’s online during peak hours, your game world will keep running smoothly.

How It Works Behind the Scenes

In plain terms, every Foundry VTT server has a guaranteed share of CPU power reserved just for it. That means your session will always remain playable — even when hundreds of other DMs are running games at the same time.

But here’s the best part: during quieter times, your server often gets access to much more processing power. So when you’re preparing your next session, installing modules, or testing new maps on a Tuesday afternoon, things move much faster.

It’s kind of like driving on a high-tech highway — during rush hour, we lower the speed limit so everyone can keep moving, but during off-peak hours, we open all lanes so you can enjoy the open road.

Smarter Resource Use = Better Value

Before introducing this system, we reserved a fixed amount of CPU for every single server. That kept performance consistent, but it also meant that half of our server resources sat unused during quiet hours.

So we asked ourselves: why not share that extra power with the people who are actually playing?

The result is a setup that’s both smart and fair:

• You’re always guaranteed a stable amount of CPU power.
• You get extra performance during off-peak hours.
• And because we use our resources efficiently, we can keep prices low.

Works Hand-in-Hand with Idle Shutdown

This feature pairs perfectly with our Idle Shutdown system. Together, they make sure every bit of server power goes where it’s actually needed.

By shutting down idle servers and redistributing resources intelligently, we can keep Foundry hosting affordable without sacrificing performance when it matters most.

Real Results for Real Game Masters

Many GMs have already noticed the difference. Those who prep their sessions during off-hours can now install modules faster and set up complex scenes in record time. And come game night? Everything just works.

In short: Guaranteed CPU means your world stays responsive, reliable, and ready for adventure — no matter when you play.
