Unigine Superposition -What Is DXGI.DLL Error?

Halo.When using Unigine Superposition 1.0v. Sometimes i get app error Superposition.exe dxgi.dll error in event viewer.
Its sometimes when i exit to desktop from GAME MODE or benchmark mode. Or when i alt tab to desktop and back again to test, it crash too with that error log in event viewer. But exiting is normal ,just that log same. No driver crash,by the way.
During test all is fine, i have scores. Stress test mode passing fine too.

Desktop 1440P res. Benchmark/game mode / 1080p

Testing Unigine Superposition 1.1v no error. If i can ask. What is dxgi.dll error? And why it was appeared on 1.0 version. During quitting benchmark or alt tabbing back to test. One time it crashed with this when i alt tab out froM GAME MODE to desktop.

I have here 1.0 it no problem no error! Maybe because this 1.1 is for VR mode!

Yeah so why i have error only on 1.0v? desktop is on 1440P test is on 1080p

It hard to understand why cause crash on 1.0 which I never had any error on my lol!!
Have you try reinstall again? When you have uninstalled so use CCleaner and delete superposition folder then reboot so try again install!

It just showing error in event log after quitting benchmark or alt tabbing to test. Only in event log.

What is the Event ID number?

its app crash. Faulty module: dxgi.dll. Code exception: 0xc500000

Look like you have two version 1.0 and 1.1 in same folder maybe that may cause crash so have you try clean install again Superposition?
