If you happen to have an NVIDIA GeForce graphics card and are experiencing crashes in the client while in Fullscreen mode (either during the ALT TAB operation or switching from Fullscreen -> Windowed), this seems to occur when NVIDIA's In-Game Overlay is enabled.
One recommendation would be to disable NVIDIA's In-Game Overlay to see whether this helps.
This can be done by opening "NVIDIA GeForce Experience" and doing the following:
1) Go to Settings (the Gear button)
2) In the General area scroll down until you see the In-Game Overlay option
3) If that option is enabled set it to disabled
Once done check to see whether that has made any difference.
As of 1.10.11 the client now has an option that allows you to toggle VSync (though only effective while uncapped is enabled).
If input lag has been experienced, you "may" want to disable VSync, however that does introduce the potential risk of what has been referenced below.
With VSync disabled there is a potential risk of screen tearing occurring if you happen to use Fullscreen mode, in which case the only options available for that circumstance are:
1) Switch to Windowed mode
2) Re-enable VSync
3) Both (1) and (2)
4) Disable Uncapped
It has been a couple of years since the last release, however a new version of the ZSMulti is available:
Although this is a major release the vast majority of the changes are internal:
* Improved Stability
* Maximum number of possible instances has been increased to 100
* The ZServ instance definitions and process-related information are now stored in separate files.
*** WARNING: Before upgrading, be sure to backup the following items:
**** The zsmulti.exe is to be placed into the same directory as the ZSWizard executable.
If there are any problems, send a "detailed" message to me indica...
I've had the rather dubious pleasure of receiving reports regarding spoof websites that redirect elsewhere.
To be quite blunt, you have to be pretty bloody stupid to do something so blatantly underhanded.
Or it's just to ferment further headaches.
Quite simple in this case: Don't do it.
