Low and Medium were costing too much at 4K because of the upscaled UI layer, so it's off there now. Muzzle flashes, tracers and missile smoke (1998 had none), scorch, craters and wreck smoke that fade after six minutes, and rebuilt menu art. Then 38 review questions answered in one go: a lighter host-station shadow, more glow at higher levels, towers that are still too clean and flat, and modern rebuilt icons in place of the AI-upscaled ones.
