New vulkan renderer not fully utilising intel arc gpus

Only getting 30-45 fps on intel arc b580, while the game is only using 15% of my gpu. Render distance 12, anisotropic filtering on, otherwise default settings.

Environment

OS: Kubuntu 25.10, modified with kisak mesa PPA to get latest arc drivers

Accidentally submitted without finishing typing, here is the rest of my info: GPU: Intel Arc B580, CPU: AMD Ryzen 5 3400G, 32GB DDR4 Ram. Screenshot:

Can also confirm that this happens with AMD GPUs as well. Vulkan uses considerably less power than OpenGL, but also renders less frames as a result.

CPU: AMD Ryzen 7 9800X3D w/ 32GB DDR5-6000 RAM

GPU: AMD Radeon RX 9070 XT
