Title: Aimtrak and Steamlink - Shaky cursor?
Post by: dammit57 on December 11, 2019, 06:11:57 pm

First off, hello everyone, great forum you have here. I've been reading allot of posts here recently and getting lots of great info, thanks. I've just joined up with the hope that maybe someone could offer some advice..

I've recently been getting an emulation setup together where I use a Valve Steamlink plugged into my large loungeroom television, on which I stream games and emulators across wired Ethernet from my PC which is in another room of the house. (It's an older 2010 machine, running Windows 7 64bit, though all the games seem to run fine).

I've been trying to get my Aimtrak Lightgun to work with the Steamlink, but am having no luck unfortunately. Whenever I plug the sensor bar and gun into the USB ports on the Steamlink, the mouse cursor starts jumping all around the screen. It seems to have some relation to the position I'm holding the gun, like some of the positional information is getting through, though it's as if the pointer has had it's sensitivity turned way up and there's extreme shake on the cursor.
Plugged straight into my PC (No Streamlink) the Aimtrak works great and I'm able to load games through Steam (As is required by the Steamlink) and play them fine. It's just when plugged into the Steamlink, and streaming to my television I have the issue.

On the Steamlink i've turned the mouse sensitivity all the way down and it hasn't helped.

I've tried a standard wireless USB mouse on the Steamlink and the cursor movement is fine.

I've also tried plugging the Aimtrak and Sensor bar into a powered USB hub, then into the Steamlink, but the cursor still shakes erratically.

I just wanted to ask if anyone here has experimented with a similar setup, or experienced a similar shaky cursor with their Aimtrak + Steamlink?
I've heard mention of a USB streaming App for the Steamlink called "Virtualhere", which enables various USB controllers, but I'm not sure if this would help with the Aimtrak.

Any help or advice would be appreciated. Thanks for your time :)

Have you tried opening the aim trak utility and seeing what its doing in the diagnostics?

Sorry I dont have any specific advice having never done this myself.

But my 2 initial guesses would be 1) Extreme lag caused by the streaming box (possibly a driver issue??) or 2) when this happens on a normal setup its normally caused by interference or heavy light/reflections.
I.e. playing next to a window or mirror.

Thanks for the reply Titchgamer.

Those are some interesting leads, I'll look into them more and experiment this weekend. 

This setup has got allot of potential as a big-screen lightgun solution, if I have any luck or come across a fix I'll be sure to post it here.
