If Undertale runs slowly on your PC, first identify whether the problem happens in the game itself or only while streaming it remotely. The official Undertale FAQ documents a slowdown fix in version 1.08 for some Windows 10 PCs, but that does not establish a universal fix for every current performance issue. If you are asking about multiplayer, Steam lists Undertale as single-player; remote streaming is not native online co-op.
Why is Undertale lagging on PC?
“Lag” can describe different problems: the game may run slowly or stutter locally, fail during startup, or feel delayed only when streamed over a network. Where and when it happens helps determine which steps are relevant.
- Slowdown or choppiness while playing locally: check the game’s requirements and whether other applications are using system resources.
- A graphics initialization or D3D surfaces error: use the official FAQ’s launch troubleshooting steps below.
- Delay only during Remote Play or another streaming session: investigate the streaming connection and settings, not just the game installation.
Fix a graphics initialization or D3D surfaces error
For this specific launch error, the official Undertale Windows FAQ recommends closing other programs, reducing the game’s resolution, and making sure video-card drivers and DirectX are up to date. These are the FAQ’s steps for the graphics initialization problem, not guaranteed fixes for every kind of slowdown or stutter.
Check local slowdown and stuttering
Steam lists these Windows requirements for Undertale. They are the store listing’s requirements, not a guarantee of a particular frame rate.

Steam’s general performance guidance notes that meeting minimum requirements alone does not guarantee high FPS. Close unnecessary background applications and compare your PC with the listed requirements before assuming a hardware upgrade is needed. Steam separately states that its client supports Windows 10 and later as of January 1, 2024; that client-support statement is distinct from the game’s listed operating-system requirements.
The official FAQ’s version 1.08 patch notes say: “Fixed an issue where the game would slow down on some Windows 10 PCs.” That is evidence of a fix for an issue affecting some systems at that time—not proof that every present-day slowdown has the same cause.

When the delay happens only during Remote Play
A streamed session adds network and video/input transport between the host PC and the player’s device. Steam’s general performance guidance treats online lag as high network latency and recommends checking latency, region, background applications, and router conditions. Those checks apply when an online or streaming layer is involved; they do not diagnose a local Undertale frame-rate problem.
For Remote Play, Steam’s streaming guidance suggests using a wired network, lowering resolution, disabling vertical sync in the game settings, and adjusting Remote Play quality or bandwidth settings. These are platform-level suggestions, not Undertale-specific test results. Host performance, the client device’s ability to decode video, connection quality, and image-quality settings can all affect how a streamed session feels.

Can you play Undertale multiplayer on PC?
Steam lists Undertale as single-player; its listing does not identify native online co-op. Remote Play or other streaming features can let someone view or interact with a streamed session, but they do not change the game’s single-player classification. Fan-made modifications or third-party input-sharing approaches are unofficial and are not native multiplayer modes supported by the store listing.
Try a joypad for different controls
The official FAQ says a joypad can be used as an alternative to keyboard controls. A controller may suit your preferred way to play, but the FAQ does not describe one as a performance fix.
