r.VT.MaxUploadsPerFrame.Streaming

If positive, max number of page uploads per frame in game for streaming VT. Negative means no limit. If zero, SVTs won't be budgeted separately. They will be limited by r.VT.MaxUploadsPerFrame along with other types of VTs. This is the old behavior. This limit should be high if streaming pages is slow so that I/O requests are not throttled which can cause long delays to acquire page data.
