Yes it’s fine to have this warning.
We use a 64M staging buffer pool to reduce the allocation overhead of pinned memory, which is used in buffer uploading/downloading. If the concurrent data transfer between the CPU and GPU exceeds this 64M pool size, we then have to allocate non-pooled ad-hoc memory, hence the performance warning.
In LuisaRender, this might occur when uploading large meshes to, or downloading large frame buffers from the GPU, but both do not happen frequently. So it should be safe just to ignore this warning.
