Dimraeth system requirements
The Steam page asks for Windows 10, a 4th-gen Core i3, 4 GB of RAM and a GTX 750 at minimum, and a GTX 1050 Ti with 8 GB of RAM recommended. In practice you need a graphics card with 4 GB of VRAM, and the co-op host needs about 4 to 5 GB.

Minimum and recommended specs
Only Windows is listed. For other systems, see Dimraeth platforms.
The graphics card is the real floor
A laptop that meets the store minimum can still run at about 30fps in town, lower elsewhere, with choppy sound on the lowest settings. The developer’s answer:
“I may need to raise that minimum as I think the GPU referenced usually has 2GB of VRAM but you really need 4GB of VRAM as development has continued.”
“For scaling in the future we do not believe any more resources will be required, but with all the stuff added the minimum has creeped up.”
Do not expect the minimum to come down much with optimisation. Check your card against this:
The Steam Deck holds 60fps, so the bar is not high in absolute terms; see Dimraeth on Steam Deck.
Hosting co-op needs more than joining
A player who joins only renders what is on their own screen. The host also runs the monsters, quests, events and farming timers, and some of that work sits on the main thread, so an old CPU slows the whole session. The host also needs about 4 to 5 GB of VRAM.
Let the player with the newest CPU and the most VRAM host. Task Manager can show most cores idle while the main-thread core is maxed out. Who hosts, and what carries over between worlds, is on Dimraeth co-op and multiplayer.
Stutter while walking around
There are two kinds of stutter. Work out which one you have before changing settings.
- Stutter at a bridge or zone edge
The open world has no loading screens, so areas load and unload as you move. Crossings like the Earlwood bridge to the farmlands hitch on lower-spec hardware. This is expected, and enemies and quests are kept away from those spots.
- Stutter every few seconds, everywhere
Your player.log file may be filling with errors and overloading disk writes.
- Send the player.log to a developer
Join the Discord and share your player.log so a developer can look at it. The invite link is on the Dimraeth community page, and the player.log folder is on Dimraeth stutter and lag fixes.
Crashes to the title screen and failed saves are a different problem, traced to security software blocking save writes. The fix is on Dimraeth bugs and fixes.
