[Linux/Nvidia ]Much lower FPS in Vulkan than in OpenGL #76

Open rcano opened 8 years ago

rcano commented 8 years ago

Vulkan yields about 60-70% of what OpenGL yields, but it seems to be maxing GPU usage at 99%, also using more VRAM but less PCIe bandwidth, sitting at 7% while opengl sits at 11%. The video card is an Nvidia Quadro K2100M.
