This does seem to be the case, if I enable uts/dfs in UMS (with
BusTypePCIE) I run out of CPU while playing a youtube vid.
One possibly interesting thing I found is that disabling dfs when using
KMS has no effect - but Option "EXANoUploadToScreen" cures the problem.
It still eats more CPU than UMS - but then so does xv and x11.
