R_ShadowJittering - This setting controls the way the edges of shadows 'jitter' in the game, effectively blurring and covering up jagged shadow edges. If you want even better shadow quality, you can set higher values such as 2048 or 4096, but this will bring about a major drop in performance. The lower the setting, the less objects will cast shadows, which can improve performance at the cost of realism.Į_shadows_max_texture_size - This setting allows you to set the resolution for the shadow maps in the game, with resolution values such as 256, 512, 1024 progressively providing sharper and more detailed shadows at the cost of a drop in FPS.
