It was also poorly documented, but it seemed that I had what I needed - this question on StackOverflow also gave me hope that it was doable. However, I did note on this MSDN Forums post that 'RelativeMouseMode is not supported in RDP RDSH/RDVH scenarios and should not be used', but I figured to heck with it, it's not a real production environment, and I was fine using a feature that is not supported. Thanks to answer, and in particular the post he linked to, I was able to follow the lead, and eventually discovered that amongst the many interfaces implemented by the Remote Desktop Client ActiveX, one of them supports a RelativeMouseMode property! That sounds like exactly what I need, it will force the RDP to support relative mouse movements! Well, mostly solved it - it is functional, but not without drawbacks. Wow, after a ton of research and failed attempts, I actually solved this! I am hoping to find ANY kind of solution to this. it seems it is still reporting it's location 'left of center' instead of 'moving to the right'). the mouse is still to the left of center, but moving to the right) it continues to jump left. if I move the mouse a bunch to the left, the view jumps crazily to the left if I then move it a bit to the right, but still not all the way back to center (i.e. location-based mouse and not motion-based), and also with the in-game behavior - e.g. move it out the window on the left, back in on the right - and it behaves perfectly, i.e. This 'theory' correlates well with some explanations of how the mouse pointer jumps in and out of the RDP window (e.g. in the game menus the mouse is just fine).Ĭlosest I could tell, from both experimentation and much searching online (many other people had the same problem, but no solution found) - it seems the mouse driver transmits its relative location, instead of movement. The problem is that the mouse reacts quite crazily when in game - but completely normal outside of the 3D environment. It definitely allows games to be very playable over RDP (if it weren't for the mouse).
