I have just installed ZS1 but am getting terrible screen flickering. It starts flickering immediately with the loading screen and never stops. The flickering slows down when an explosion happens, but speeds back up when the explosion clears.

I have tried compatibility mode, messing with the few settings in the config file, and changing settings in the ATI Control Panel. No change in behavior.


Win10 Pro x64, 4GB, ATI Radeon HD6450, 1440x900, driver 15.20.1062.1004

I get the same thing...my screen flickers while the game is going...what gives?

Alien Shooter is doing the same for me in Windows 10. Sadly, neither game is yet marked Windows 10 compatible by GoG.
R9 290 for me. Anyone else having better luck? Do NVidea cards work?

Yes, that works! Thank you!
