Install the October 16, 2026 update or a later available update and restart the game. Version 26.10.16_57fb763 includes the fix for terrain becoming invisible on some older GPUs, including affected Nvidia GTX-series hardware. The previous -msTessOnce 0 Steam launch option is no longer required for that fix.
The developer states that the correction applies automatically with the update, whether or not you previously used the launch option. Start with the update instead of treating an old workaround as a mandatory setup step for every player.
Apply the shipped fix first
- Exit Over the Hill.
- Allow Steam to download and install the available update.
- Relaunch the game and revisit the place where the terrain was invisible.
- If the problem remains, record your game version and GPU model before trying to describe it as the same fixed issue.
Do not judge the fix from a session that was already open before updating. Restarting makes the test about the installed update rather than the previous running build.
This image shows visible ground in normal gameplay. It is a visual reference for the expected terrain, not a before-and-after test on your particular graphics card.
Understand the old launch-option advice
Before the update, affected players could work around the problem by adding -msTessOnce 0 to Steam launch options. The October 16 announcement says that behavior is now included automatically.
| Situation | Appropriate next step |
|---|---|
| Game has not been updated | Install the update and relaunch |
| You never added the old option | No extra launch option is required for the shipped fix |
| You previously added the old option | The developer says the update applies regardless |
| Terrain is still invisible after updating | Record the hardware, version, symptoms, and Player.log for support |
The old workaround's existence is not evidence that every terrain problem has the same cause. It addressed the specific older-GPU issue named in the announcement. A different rendering fault on another configuration needs its own description.
Keep other visual issues separate
The same update also fixed white particles that could appear along terrain creases. That symptom is different from the ground itself becoming transparent or invisible.
Likewise, poor frame rate, ordinary camera obstruction, and an infinite loading screen should not be merged into a single invisible-terrain diagnosis. Describe what you can see and when it happens. A precise report is more useful than applying every unrelated launch parameter from an old thread.
If the updated game still fails
Collect the GPU model, game version, a screenshot of the affected scene, and Player.log. Include where the problem occurs and whether it happens immediately after loading or only during a particular route. If you had already used the old launch option, mention that as part of the reproduction details.
No universal second fix is confirmed here. Avoid deleting saves, using an unverified configuration edit, or assuming a hardware replacement is necessary merely because the shipped correction did not resolve your case. The useful next step is a reproducible report that distinguishes your remaining issue from the one fixed on October 16.
