RDC vs. TightVNC vs. RealVNC

Any thoughts on which is best, provides the best performance/feel?  I've tried the two VNCs, but only have XP Home (came w/ computer), want to know how good RDC is before shelling out more coin.

My guess would be RDC, since it Citrix engineered this thing right from the start to let users run GUI applications from a remote host. Incidently, I'm waiting for a customer to install an XP or Win2003 Server, so that he can test running our app from a remote location through the Net. Can't wait to see how it performs compared to UltraVNC.

RDC is better, but works well only against XP or WIN2K3 (or Citrix ..); It also transports sound. Also, on XPs that do support it, it disables the local user.

UltraVNC is very good, and works on just about any Windows version.

RDp / RDC / TS wins, every time.

I agree.  It's not really a contest either -  RDP solutions win by a mile.

Is it true that RDP actually offloads the drawing to the local PC and sends only "drawing instructions" over the wire, so for instance if you have a program installed locally and access that same program on the remote computer it will run faster than somebody running it from the same host but without it installed locally?

I just read this somewhere ages ago, and it seems to be true because if you access a XP machine with themes turned on from a Windows 2000 machine it seems slower than accessing via Windows XP machine.

(Of course this would be in contrast to VNC solutions that send BMPs of the screen over the wire)

Please tell me if I am being completely stupid for even believing this, because the increased speed could of course just be a placebo effect after reading about it.

Of course custom BMPs still are slow to render, but menus and messageboxes and OS icons seem to render almost instantly if you are using the same OS as the remote computer.
