as for me autocad 2014 crash with fatal error if precision X 16 is running. No problem with older version.

Where can i download a version just before 5.2.0?

same trouble here i need to find an older version some how

Found a fix for this I believe.  With EVGA Precision running look in the bottom right corner next to the clock for the icon for the EVGA PrecisionX 16 Server v5.2.0. Double click it to open it. Small window opens with a scroll list of .exe programs. Hit the Add button then look for whatever program you are trying to use and add the .exe for that program to the list. If the program has multiple .exe for it then add both/all of them. Was having the issue with Diablo 3 mainly and tried just adding the diablo3.exe and it worked. No more crashing. Don't know if it will work for the other programs but I don't see why it wouldn't. Now for Diablo 3 there are multiple .exe but you may not need to add them all as i didn't need to but I have been adding the battle.net.exe to the list as well as the launcher.exe variant just to be on the safe side. Sad to say the list doesn't seem to save and I have yet to find a way to save the list. Have tried redoing the profile under the precisionX program after adding them hoping that would than save the list but no such luck so far. So make sure you re-add the .exe files to that server list if you reboot your computer as it loses it between reboots and shut downs.
 
Hope it helps, will be posting this in the Diablo forums as well.

yes this trick work well with autocad 2014. Strange that in my case diablo 3 work well with precision x16 without need to add it in precision x16 server... only autocad 2014 (autocad 2012 work well)

Here is the Windows Live Mail problem with Precision X 16.

add windows live mail to the precision x16 server

can also confirm it messing up hearthstone and league of legends. When i have Precision X 16 up and running league will have graphical issues where the screen freezes in the client. When i play hearthstone it will crash the game with no error report a few steps into the game or when im messing around with my cards in my collection. If I exit out of Precision X 16 everything runs just fine.

New version still causing the issue. Can't change resolution or alt+tab. Does it with Counter-Strike Global Offensive as well. Once I uninstall Precision X the issue no longer happens.

I also just tried the newer version and it still causes hearthstone and league of legends to have graphical issues. These games only start working AFTER I un-install precision-x. However, the older version of precision x that was linked there "precision x15" is working perfectly and my games arent crashing......I dont like this "server" thing though.

The solution is to add in C:\Program Files (x86)\EVGA\PrecisionX 16\PrecisionXServer.exe the program x86 which crash and in PrecisionXServer_x64.exe the program x64 (like autocad) which crash.

you must to add hearthstone.exe in precisionXserver.exe to solve your crash problem.
with autocad the problem is a little bit complicate because acad.exe autodelete in precisionXserver_x64.exe
