@peanar3d: Stop the Stutter: Make Blender’s Viewport Fly 1. Vulkan backend (4.5 LTS): Edit → Preferences → System → Display Graphics → Backend: Vulkan. Requires restart; optional; Cycles doesn’t use it. If it’s worse on your rig, revert. 2. Alt+D: Linked duplicates = less VRAM; go Single User only when you truly need unique data. Saves memory instantly 3. Render Properties → Performance → Viewport Pixel Size: Set 2x/4x for a lighter viewport, especially on high-DPI displays. This scales the viewport resolution, not your final render. 4. For heavy assets: Object Properties → Viewport Display → Display As: Bounding Box. Instant navigation relief; switch back when you need to edit details. 5. Render Properties → Simplify → cap Max Subdivision, reduce Child Particles, and apply a Texture Limit while working. Remember to restore settings for finals. #blender #3dmodeling #tips #fyp
