3. Tick Development Build
4. Tick Autoconnect Profiler
5. Build And Run on an Android device
6. Observe the Profiler
Expected result: InstantiateDeformationSystem and SkinningDeformationSystem do not spike CPU Usage
Actual result: InstantiateDeformationSystem and SkinningDeformationSystem spikes CPU Usage by about 0.06 KB in every frame
Reproducible with: 1.0.0-pre.44 (2022.2.9f1)
Could not test with: 1.0.0-exp.8 (2022.2.9f1), 1.0.0-pre.15 (2022.2.9f1) “com.unity.ext.nunit@1.0.6/net40/unity-custom/nunit.framework.dll' could not be found”

Resolution Note:
The deformation system in Entities Graphics is still experimental.
The GC allocation comes from retrieving the GraphicsBuffers from the mesh. This is a request to either have a non gc allocating graphics buffer or a caching mechanism in Entities graphics. The latter will only reduce the problem but not take it away.
