I moved the app to the latest D3D12 version we have and it actually revealed a problem with D3D12 and multiple 3D lights. On D3D9: <img width="1103" height="728" alt="image" src="https://github.com/user-attachments/assets/2c8270d7-5376-494f-b249-717ac7ae997a"; /> On D3D12: <img width="1103" height="728" alt="image" src="https://github.com/user-attachments/assets/fb4fe2ff-9597-4de3-9be4-d62c22ca6b95"; /> We tested multiple lights on D3D12 at an earlier point, so I suspect something broke in recent changes. Regardless, the problem seems visual so I would assume the framerate is indeed higher - avg 212FPS on D3D vs avg 244FPS on D3D12 (both cases have 10000 meshes and all three point lights enabled with range 100). I'll do more testing on D3D12 with this when we merge the update to the repo =) ------------- PR Comment: https://git.openjdk.org/jfx/pull/1387#issuecomment-5951866323
