GPU General Counter

• VertexOccupancy：Measures how many vertex shader simdgroups are concurrently running in the GPU relative to the GPU’s maximum number of concurrently running simdgroups.

• FragmentOccupancy：Measures how many fragment shader simdgroups are concurrently running in the GPU relative to the GPU’s maximum number of concurrently running simdgroups.

• ComputeOccupancy：Measures how many compute shader simdgroups are concurrently running in the GPU relative to the GPU’s maximum number of concurrently running simdgroups.

GPU Memory Counter

• BufferReadLimiter：Measures the time during which buffer loads are attempted to execute as a percentage of peak buffer load performance.

• TextureSampleLimiter：Measures the time during which texture samples are attempted to execute as a percentage of peak texture sample performance.

• GpuReadBandwidth：Measures how much memory, in gigabytes per second, are read by the GPU from a memory external to the GPU (potentially main memory).

• GpuWriteBandwidth：Measures how much memory, in gigabytes per second, are written by the GPU to a memory external to the GPU (potentially main memory).

GPU Shader Counter

• Alulimiter：Measures the time during which ALU work is attempted to execute as a percentage of peak ALU performance.
