Hello @masterzone3d, we're using one issue report per unofficially supported game title, so I've gone ahead and transferred this issue report to https://github.com/ValveSoftware/Proton/issues/8694#issuecomment-4280777418.
Hello @masterzone3d, we're using one issue report per unofficially supported game title, so I've gone ahead and transferred this issue report to [#8694 (comment)](https://github.com/ValveSoftware/Proton/issues/8694#issuecomment-4280777418).
I understand the merge, but I would like to highlight that this is a specific graphical regression introduced with the latest game update (aimed at fixing AMD crashes).
Issue: Dynamic tree shadows suffer from an extremely aggressive clipping distance on Steam Deck. They disappear just a few meters away from the camera.
Technical Findings:
Comparison: This issue does not occur on PC using the same "Low" settings. It seems to be a Steam Deck-specific profile change or a side effect of the recent stability fix for AMD GPUs.
Workaround: Increasing the "Details" parameter to "High" fixes the shadow draw distance, but this was not necessary before the patch and impacts performance on handheld.
Hypothesis: The fix for AMD stability likely introduced a hard-coded shadow culling limit specifically for the Deck's hardware profile or when running under Proton, which is now tied incorrectly to the "Low" detail preset.
I hope this helps the team investigate if the shadow distance parameters were unintentionally throttled for Steam Deck users in the latest build."
System Information
I confirm:
Symptoms:
Based on latest official game update, now the dynamic shadows are rendered very closed to the camera instead of a standard game draw distance with "low settings". Previously shadows were rendered very far from the camera.
On Windows PC dynamic shadows are pretty good with same settings.
