Hello there @DannyManPc!
Checking around the community, while there are no direct switches to simply toggle these features, there are a few commands we can test to adjust their behaviours, and work accordingly to your objective. Let’s cover them one by one:
-
First, we can force VSM to use the cache more often:
- r.Shadow.Virtual.Cache 1 (this one should reduce updates when anything moves due wind effects)
- r.Shadow.Virtual.MaxPhysicalPages 4096 (will prevent the cache from being cleared so often)
-
Next, for WPO, you can disable the feature per mesh instance in Details, but it won’t be as effective with foliage and WP (check this related thread for further details)
-
However, you can achieve a similar effect with the following:
- r.MaterialQualityLevel 0 (this will force the materials to remain at a low value)
- r.RayTracing.Geometry.StaticMeshes.WPO 0 (should disable WPO for ray tracing and shadows)
Test your scene with these commands implemented, and check for perfomance changes. You can further evaluate impact using the features from Insights.
