Wacom tablet usage in 2012 R2 RDS
Setting up a RDS server on 2012 R2 for a medical client.
Everything is going swimmingly except for the doctor who likes to use a wacom graphics tablet.
He uses it for writing script orders, signing labs, etc.
In any case, it is a vital part of his work, and he needs to use it.
when he uses it in his RDS session, it sometimes misses when he picks the stylus up from the tablet, and so he will have a solid line from the bottom of on letter to the top of the next - as an example. When he writes at a normal pace, it gets bad enough that it is difficult to read - he prints, so even though he is a doctor, his normal handwriting is legible.
The closer to his normal speed he gets, the less of the words and letters are actually picked up.
It is a small practice, so I really don't want to buy citrix or another pricey RDS enhancer... is there a tweak that can be done to Server 2012 R2 that will speed up his stylus?
The RDS host is Server 2012 R2, the client is Win 7 Pro Sp1, both fully patched. The network connection is a 1Gbps synchronous WAN link at a COLO for the server, and a 100/10 broadband link at the practice.

I've done lots of work in this (see my previous posts through the years). Even went as far as using VDI and remote FX. Nothing really works. Only Citrix makes it work. There's a reason it's so expensive, they are making things work in a remote environment that Microsoft has refused to do for a decade. I tried every registry and driver tweak I could find.

How about just making the mouse cursor glide smoothly in RDP?
I've tried the min send interval setting at 1, and it helps, but is not as good as it could be.
Any other ideas?

We set the absolute minimum by both registry and on the thin client software we were using (Wyse ThinOS 8.0.1 for server 2012 R2) and while it got close it was never smooth. Citrix made it butter smooth.

Can you draw completely smooth lines with it? When we messed with Windows ink we didn't get much better, but that is feeding the tablet through a Wyse thin client with the USB device registering directly onto the server, not the pen acting as a mouse in a client OS passing directly to a RDP session.

Almost.
If you zoom in, you will see that there are some angles, but for our purposes, it is more than sufficient.
Please note, that I am using an older bamboo tablet that I have zero experience with, and it looks that shaky/bad on my pc, not just in RDP, mainly because I have trouble writing while looking at the monitor.

I found the only solution that worked.
The only tweak I can find that may improve things is to add DWORD "Min Send Interval" (no quotes) at
HKCU\Software\Microsoft\Te
with a value of 1. That should decrease the amount of time between "Mouse" input changes that get sent to the server's session. But like I said, there isn't yet any real support for pen/digitizers in Remote Desktop right now.
