What do you need to know about GPU shark?
GPU Shark offers a global view of all your graphics cards in a single window. GPU Shark can display for every GPU the clock speeds (GPU core, memory and shader processors), performance states (or PStates), GPU fan speed, and GPU/memory/MCU usage. GPU-Shark gives an overview of all your GPUs and has two viewing modes: simplified and detailled.
Which is the highest state of a GPU?
The GPU performance state APIs are used to get and set various performance levels on a per-GPU basis. P-States are GPU active/executing performance capability and power consumption states. P-States range from P0 to P15, with P0 being the highest performance/power state, and P15 being the lowest performance/power state.
Is there a free tool for GPU monitoring?
GPU Shark is a simple, lightweight (few hundred of KB) and free GPU monitoring tool, based on ZoomGPU, for NVIDIA GeForce and AMD/ATI Radeon graphics cards. GPU Shark is available for Microsoft Windows only (XP, Vista and Seven). GPU Shark offers a global view of all your graphics cards in a single window.
Which is the NVAPI interface for GPU performance?
Instead, use NvAPI_GPU_GetPstates20.”) NVAPI_INTERFACE NvAPI_GPU_GetPstatesInfoEx (NvPhysicalGpuHandle hPhysicalGpu The GPU performance state APIs are used to get and set various performance levels on a per-GPU basis. P-States are GPU active/executing performance capability and power consumption states.
Why is my GPU running out of video memory?
There are a lot of possible root causes for stuttering; one of the most common is video-memory overcommitment which happens when an application is using more video memory than is physically available on the GPU.
Why are there gaps in the GPU graphics queue?
Note that you can have large gaps in the GPU Graphics queue and not have stuttering, if the gaps are always consistent. The reason these gaps are causing stuttering is because they are of variable length. Let’s zoom in to the first frame from Figure 2 — after the first Present packet and up to the next Present packet.
How to tell if an application is running out of video memory?
To determine whether a Windows application is running out of video memory or not, the first thing I do is capture a GPUView trace (see Appendix) from a run where stuttering is happening consistently. I then open up the trace in GPUView and:
